In Brief<br />

Southern Indiana City Plans Solar Farm<br />

to Power Sewage Plant<br />

BOONVILLE, Ind. (AP) — A southern Indiana city is<br />

aiming to hold down future increases in sewer bills by<br />

building a 4-acre solar farm.<br />

Boonville officials are moving ahead with an estimated<br />

$1.7 million project for the field of nearly 2,000 solar<br />

panels to power its new sewage treatment plant.<br />

The city expects to sell excess electricity that’s generated<br />

to the utility company Vectren. Projections are that<br />

the city will save about $17,000 a month or $6 million<br />

over the next 30 years.<br />

Mayor Charles Wyatt says he’s glad the city about 15<br />

miles northeast of Evansville can use green energy to<br />

reduce expenses for the sewage plant.<br />

Fermi Two Nuclear Plant is Back Online<br />

Following Repairs<br />

FRENCHTOWN TOWNSHIP, Mich. (AP) — A nuclear<br />

power plant in southeastern Michigan is back online<br />

after being shut down last month for repairs.<br />

The Monroe News reports DTE Energy’s Fermi 2 plant<br />

in Monroe County was synchronized to the electrical<br />

grid on Jan. 1.<br />

DTE Energy spokesman Stephen Tait says the plant<br />

“was maintained in a safe, stable condition throughout<br />

the outage.” The plant was taken offline Dec. 6 as<br />

operators looked into an electrical issue on the plant’s<br />

main generator, which is on the non-nuclear side of<br />

the plant. The issue was traced to a ground fault.<br />

The Detroit-based utility’s plant is located along Lake<br />

Erie in Frenchtown Township, near Michigan’s border<br />

with Ohio.<br />

Rock Falls Planners Object to Proposed<br />

Community Solar Farm<br />

ROCK FALLS, Ill. (AP) — Planning officials in a northwestern<br />

Illinois community are opposing a proposed<br />

community solar farm just outside its city limits.<br />

Sauk Valley Media reports that the Rock Falls Plan<br />

Commission recommended that the city object to the<br />

project, saying it is incompatible with comprehensive<br />

plans of the city and Whiteside County.<br />

The proposed project site is in an agricultural area. The<br />

city contends the site should continue to be used for<br />

farming until it can be developed for more traditional<br />

commercial purposes.<br />

Minnetonka, Minnesota-based Sunrise Energy Ventures<br />

has applied to the county for a special-use permit for<br />

the project. Rock Falls has a say in the matter because<br />

the site is within a 1.5-mile radius of its borders.<br />

Rock Falls is about 115 miles (185 kilometers) west of<br />

Chicago.<br />

Michigan’s $52M for Lock May Speed<br />

Construction, Save Money<br />

LANSING, Mich. (AP) — Michigan’s commitment of<br />

up to $52 million toward construction of a new Great<br />

Lakes shipping lock could accelerate the project’s completion<br />

by a year and save taxpayers $30 million.<br />

Gov. Rick Snyder and the U.S. Army Corps of Engineers<br />

released the figures Dec. 26 while announcing a memorandum<br />

of agreement.<br />

Michigan’s funds will be used to pay for design work<br />

and a portion of a channel deepening project that will<br />

be an important step toward building a second largesized<br />

lock at Sault Ste. Marie to accommodate freighters<br />

that haul iron ore and other bulk commodities. The<br />

federal government is spending $32 million on the<br />

channel deepening.<br />

Congress has authorized funding for the second large<br />

Soo Lock but must appropriate funds over numerous<br />

years to pay for the $1 billion project.<br />

Cleanup Set for 200,000 Waste Tires<br />

Left at Indiana Business<br />

ANDERSON, Ind. (AP) — State environmental officials<br />

are stepping in to clean up nearly 200,000 shredded<br />

tires left at a former central Indiana recycling business.<br />

The Indiana Department of Environmental Management<br />

estimates cleaning up the Green Tire Reclamation<br />

site in Anderson could cost up to $262,000 and<br />

will take about a year. The (Anderson) Herald-Bulletin<br />

reports the tires have been cut into 2-inch chunks and<br />

stacked in massive piles on the property that appears<br />

abandoned.<br />

The business opened in 2012 with permission to store<br />

5,000 waste tires it would shred for uses such as being<br />

burned in power plants or as construction fill. But business<br />

owner Dan McKenzie said in 2014 he hadn’t been<br />

able to find buyers for the shredded tires. McKenzie<br />

didn’t return phone calls to comment on the cleanup.<br />

3 Firms Eye Building Wind Energy Turbines<br />

off New Jersey<br />

ATLANTIC CITY, N.J. (AP) — At least three firms are interested<br />

in building offshore wind energy projects off<br />

the coast of New Jersey.<br />

The state Board of Public Utilities says it received three<br />

bids Friday, Dec. 28, from firms interested in building<br />

wind projects, but it wouldn’t identify any of them.<br />

A Danish wind company, Orsted, said it had submitted<br />

one of them.<br />

The state is seeking companies to build projects that<br />

would generate at least 1,100 megawatts of electricity.<br />

Orsted estimates that amount could power more than<br />

a half-million homes.<br />

Another company, Atlantic Shores Offshore Wind, says<br />

it’s interested in developing a project that could provide<br />

up to 2,500 megawatts.<br />

It was not immediately known whether that firm,<br />

which is a joint venture between Shell and EDF Renewables<br />

North America, has formally applied.<br />

DTE Energy Agrees to $840,000 Fine in<br />

Shut-Off Snafu<br />

DETROIT (AP) — A mess over billings and improper<br />

shutoffs has led to an $840,000 fine for DTE Energy.<br />

State regulators approved the settlement early last<br />

month. Sally Talberg of the Michigan Public Service<br />

Commission says the commission has “great concern<br />

when utilities violated consumer protection rules.”<br />

The investigation began a year ago, months after DTE<br />

began using a new billing system. The commission<br />

received complaints that power was being improperly<br />

shut off. More than 4,000 customers did not receive a<br />

proper shut-off notice for nonpayment.<br />

DTE has agreed to refund all deposits and reconnection<br />

fees. The utility also will be audited over its shutoff<br />

procedures until 2<strong>02</strong>0.<br />

A group known as the Residential Customer Group<br />

watched the case and objected to the settlement. Michelle<br />

Rison says the fine isn’t high enough, especially<br />

when some shut-offs occurred during cold weather.<br />

Illinois EPA Offers Grants for Wastewater<br />

Efficiency<br />

SPRINGFIELD, Ill. (AP) — The Illinois Environmental Protection<br />

Agency is offering grants to public wastewater<br />

treatment plants to improve energy efficiency.<br />

The agency has announced $3 million in grant funding.<br />

Grants ranging from $5,000 to $1.5 million will<br />

reduce energy consumption at treatment plants.<br />

EPA Director Alec Messina says the department has<br />

worked with 15 Illinois municipalities for no-cost<br />

efficiency assessments. The grant program uses U.S.<br />

Department of Energy funds to upgrade plants where<br />

the most cost savings will be.<br />

Applications for the grant are available online from<br />

the EPA. Applications are due by Feb. 12, <strong>2019</strong>.<br />

The applications will be ranked according to energy<br />

savings per dollar invested, energy rate paid by the<br />

facility and the energy cost to treat one million gallons<br />

of water at the plant.<br />

Renovation to Preserve Courthouse<br />

Once Visited by Lincoln<br />

THEBES, Ill. (AP) — A historic southern Illinois courthouse<br />

once visited by Abraham Lincoln is getting an<br />

$83,000 renovation with help from a private donor.<br />

The Old Thebes Courthouse overlooking the Mississippi<br />

River was built in the 1840s and is listed on the National<br />

Register of Historic Places. Dred Scott, the slave<br />

whose fight for freedom became a landmark Supreme<br />

Court ruling, was held in its jail.<br />

The Southern Illinoisan reports the structure fell into<br />

disrepair after the county seat moved in 1860.<br />

Goins says it “will look like new” when it’s done this<br />

summer.<br />

Texas Training for Wind Power Jobs<br />

Literally Has Ups, Downs<br />

By Andrea Leinfelder | Houston Chronicle<br />

In addition to studying hydraulics, welding and electrical<br />

theories during the seven-month program, MIAT students<br />

must learn to safely climb the roughly 300-foot towers and<br />

to rescue their colleagues should something go wrong.<br />

“That way, when they go out in the field, I’ve personally<br />

verified that they can actively protect themselves at height,”<br />

said David Moriconi, lead wind instructor at MIAT.<br />

So Snoddy attached his harness to a cable in the center of<br />

the ladder. He climbed to the top and transitioned to a platform,<br />

which involved unclipping from the cable at his chest<br />

and then clipping a dual-shock-absorbing lanyard to his back.<br />

He then attached a self-retracting line — a yo-yo-like<br />

contraption that would catch Snoddy should he fall — and<br />

unclipped the shock-absorbing lanyard.<br />

All of that had to be done before setting to work, with hand<br />

signals from below indicating that he needed to lift or lower<br />

a set of tools. And then Snoddy climbed back down the ladder<br />

in an equally safe fashion.<br />

He passed with flying colors.<br />

The test earned students a climb and rescue certification<br />

required by many employers.<br />

Tony Robinette, field operations manager for renewable<br />

energy and construction at the staffing firm System One, emphasized<br />

the importance of this climb test, saying the most<br />

catastrophic injuries often come from climbing.<br />

He also applauded MIAT, saying the students are well prepared<br />

when they graduate. It helps that MIAT has a longer<br />

training period than some other programs.<br />

“They definitely come out and hit the ground running,” he<br />

said.<br />

And to make the training more fun, MIAT held a competition<br />

on the eve of its official climb test. Moriconi clocked how<br />

quickly students could climb the ladder five times. That’s<br />

roughly the height of a single section on a wind turbine tower<br />

— and most towers have four sections.<br />

The fastest time was 1 minute, 30 seconds. The slowest time<br />

was around 4 minutes, 30 seconds.<br />

Snoddy came in second place at 1 minute, 56 seconds. Good,<br />

but not entirely satisfying.<br />

“I’m an ex-athlete,” he said, “so I wish I came in first.”<br />

MIAT College of Technology Wind Turbine Instructor David Moriconi, third from right, gives Anthony Snoddy, second from right, instructions before a<br />

ladder exercise in Houston. MIAT College of Technology has a seven-month wind power technician career training program. (Steve Gonzales/Houston<br />

Chronicle via AP)<br />

HOUSTON (AP) — Anthony Snoddy was first to climb the 18-<br />

foot ladder.<br />

The Houston Chronicle reports as the kid who found the tallest<br />

trees and front-flipped off buildings, Snoddy, 36, wasn’t<br />

worried about the height. He knew it would be part of his<br />

job maintaining and repairing wind turbines.<br />

“Just make sure you do everything correctly,” Snoddy told<br />

himself as he approached the ladder.<br />

In 2018, the MIAT campus in north Houston saw a 60 percent<br />

enrollment increase in its wind power technician program,<br />

which averaged 25 to 30 students. The U.S. Bureau of Labor<br />

Statistics expects that the field will grow to 11,400 wind turbine<br />

technicians in 2<strong>02</strong>6, up from 5,800 in 2016.<br />

Instead, he was focused on the safety clamps and procedures<br />

for climbing the ladder. These weren’t part of his riskier<br />

youthful forays, but they were essential in graduating from<br />

MIAT College of Technology and entering a workforce expected<br />

to grow 96 percent between 2016 and 2<strong>02</strong>6.<br />

Many of MIAT’s graduates could be employed in Texas, a hot<br />

spot for wind power. The state leads the nation in wind power<br />

Electric Garage Heaters for a Warm<br />

Workshop By Jim Herring<br />

Most garages are not connected to central heating, making<br />

them a large cold spot in most home heating systems. When<br />

winter comes, an unheated garage can be a cold and unappealing<br />

place for home maintenance, tinkering and other<br />

hobbies.<br />

One way to keep a garage workspace toasty even in the<br />

harshest winters is choosing a top-notch electric garage heater.<br />

Electric heaters offer several benefits over other heating<br />

systems — they don’t require venting like gas heaters and<br />

can be more cost-effective.<br />

Electric Heater Benefits<br />

One factor to consider when heating a garage is safety. Electric<br />

heaters do not pose the same risks as propane or natural<br />

gas heaters. Along with a car, truck or other gas-powered<br />

vehicles, people also store gas, oil and other flammables in a<br />

garage. Because there are no open flames or exhaust fumes<br />

with electric heaters, they’re safer to use around gas vehicles<br />

and lawn tools.<br />

Electric heaters also offer efficiencies that other heaters do<br />

not. With an electric garage heater, every bit of electricity<br />

used is converted into heat. With propane, on the other<br />

hand, only 80 percent of its fuel is used for heat while the<br />

other 20 percent is lost by-products. That fuel loss translates<br />

into inefficiency and can mean higher costs for homeowners.<br />

Electric garage heaters also provide the flexibility to provide<br />

warmth without taking up floor space or creating a tripping<br />

hazard. They can be mounted on the wall or ceiling, and angled<br />

to push warm air horizontally, vertically or in any other<br />

desired direction. These installation and airflow options are<br />

much harder to achieve with a gas garage heater.<br />

Choosing the Appropriate Heater<br />

Whether using the garage for random hobbies or a regular<br />

hangout, there are several electric heating options to choose<br />

from including radiant electric, portable heaters and fanforced<br />

units:<br />

• Radiant electric heaters are designed to target a specific<br />

area with heat, typically using infrared technology to heat<br />

the objects in the room instead of the air.<br />

• Portable heaters are easy to move around the garage, targeting<br />

heat to the necessary spots where one is working.<br />

• Fan-forced heaters move warm air throughout an entire<br />

garage for balanced, all-over heating.<br />

Consider how the heater will be best used in your garage<br />

before making a selection.<br />

Garage Heater Installation Tips<br />

How best to install an electric heater varies depending on<br />

the type. Some models may need to be wired by an electrician<br />

or trained professional, while others are portable and<br />

can be easily mounted and simply plugged in.<br />

Before hooking anything up, be sure to check the voltage<br />

requirements. With a plug-in 120V electric garage heater,<br />

Electric garage heat offers advantages that gas heated garages don’t —<br />

ventilation isn’t a problem, and costs can be lower than for gas heating<br />

systems.<br />

for example, all that’s needed is an outlet. An electric heater<br />

that runs at a voltage higher than 120, however, will need to<br />

be wired in. This will require some electrical work.<br />

Also, make sure that the model of heater is sized appropriately<br />

for the space. To ensure a heater is generating enough<br />

up their garage space should consider an electric garage<br />

High-Speed Rail From St. Louis to<br />

Chicago Faces More Delays<br />

ST. LOUIS (AP) — Railway commuters traveling between St.<br />

Louis and Chicago have yet to see faster rail journeys, despite<br />

most of the Amtrak corridor’s $1.95 billon upgrade concluding<br />

a year ago.<br />

Delays in installing and testing new GPS-related safety technology<br />

kept Amtrak trains from hitting high speeds of 90<br />

mph during 2018, as the Illinois Department of Transportation<br />

originally projected, the St. Louis Post-Dispatch reported.<br />

Trains are not allowed to travel faster than 79-mph on<br />

the route.<br />

The Illinois agency projects that 90-mph speeds will be in<br />

place for Amtrak by the summer from Alton to south of<br />

Springfield. Most of the remainder of the route is expected<br />

to implement 90-mph speeds by the end of this year.<br />

The top speeds will be used only in the more open expanses<br />

of the route outside the St. Louis and Chicago metropolitan<br />

areas.<br />

Contractors and crews from Union Pacific Railroad work both above and<br />

below the Wood River Creek railroad bridge Tuesday, May 16, 2017, just<br />

east of the Homer Adams Parkway extension railroad bridge in Alton, Ill.<br />

Workers are replacing the old steel bridge’s deck and working in the creek<br />

below. Pre-assembled sections of concrete railroad ties and track are being<br />

pulled into place to run across the bridge when the deck is finished. The<br />

work is for the new high-speed rail line between Chicago and St. Louis<br />

which is scheduled to be in service by this fall. (John Badman/The Telegraph<br />

via AP)<br />

The Illinois Transportation Department had previously said<br />

speeds of 110 mph would be reached by <strong>2019</strong>, but the agency<br />

has stopped offering predictions on when that will happen.<br />

The 110-mph speed would shave about an hour off the<br />

typical 5½-hour Amtrak trip between St. Louis and Chicago.<br />

The project was funded in 2010, largely by federal economic<br />

stimulus dollars allotted under then-President Barack Obama.<br />

Jessie Decker, an Illinois Transportation Department spokeswoman,<br />

said in an email to the St. Louis Dispatch that an<br />

early version of the safety technology, named positive train<br />

control, is in service on most of the 215-mile stretch of the<br />

284-mile corridor owned by Union Pacific.<br />

Decker noted that Amtrak is upgrading software on its trains<br />

to communicate with the positive train control system, which<br />

helps monitor trains’ position and speed. If a train engineer<br />

were to fail to respond to an upcoming signal, the locomotive<br />

would take over control and slow or stop a train to avoid<br />

a crash.<br />

Missourians Want Action Over Too-High<br />

Illinois Levee By Jim Salter<br />

action if the Sny Island Levee District in Illinois fails to reduce<br />

its levee height. FEMA didn’t respond to the alliance but told<br />

The Associated Press it is working to resolve the issue.<br />

Missouri residents have complained for years that the Sny<br />

has been built several feet too high in some spots. The 60-<br />

mile (96.5-kilometer) system is north of St. Louis and protects<br />

roughly 115,000 acres of fertile Illinois farmland.<br />

The upper Mississippi River is lined with levees that protect<br />

towns, businesses and hundreds of thousands of acres of<br />

agricultural land. But in times of flooding, water that would<br />

naturally flow over a flood plain is boxed out and forced<br />

elsewhere. Such redirecting of floodwater is especially<br />

concerning given the increasing volatility of the river, which<br />

has seen damaging flooding far more frequently in recent<br />

decades.<br />

Crews check out the 54 mile long Sny Levee that protects 125,000 acres of<br />

prime farmland as the Mississippi River continues to rise south of Quincy,<br />

Ill. Some Missouri landowners as well as environmentalists are urging the<br />

Federal Emergency Management Agency to take sanctions against the Sny<br />

Island Levee District in Illinois for raising its levee to unauthorized heights.<br />

ST. LOUIS (AP) — Missouri landowners and environmentalists<br />

are urging a federal agency to sanction a levee district on the<br />

Illinois side of the Mississippi River, arguing that the earthen<br />

barrier has been built above its authorized height, worsening<br />

flooding for its neighbors.<br />

Great Rivers Habitat Alliance, a river conservation organization<br />

based in St. Louis, sent a letter to the Federal Emergency<br />

Management Agency in October urging the agency to take<br />

NEWS<br />

“These levees have a maximum height because in some<br />

instances they’re supposed to be topped,” said David Stokes,<br />

executive director of the Great Rivers Habitat Alliance. “You<br />

don’t want to sacrifice a city to keep the farmland dry.”<br />

A study by the Army Corps of Engineers in 2017 found that<br />

40 percent of the 205 miles (330 kilometers) of levees from<br />

central Iowa to St. Louis were built above their authorized<br />

heights. Missouri, Iowa and Illinois all had levees in violation.<br />

The Sny is the longest of those systems and, some Missouri<br />

residents say, the biggest violator. The Corps has said the Sny<br />

is up to 4 feet (1.2 meters) above authorized levels in some<br />

spots.<br />

In January 2016, FEMA’s Mitigation Division asked leaders of<br />

the three Illinois counties responsible for the Sny — Pike, Calhoun<br />

and Adams counties — to show permits proving that<br />

raising the levee was authorized.<br />

Three years later, it remains unclear if any permits were<br />

provided.<br />

Mike Reed, superintendent of the Sny district, said in an<br />

email to The Associated Press that the levee district is working<br />

with FEMA “to clear up questions that may remain as to<br />

the authorized levee elevation.”<br />

FEMA spokeswoman Cassie Ringsdorf said in an email that<br />

the agency “has been working with the state of Illinois and<br />

the U.S. Army Corps of Engineers to determine the best<br />

course of action to address those issues.”<br />

In the Oct. 8 letter to FEMA Mitigation Division Director<br />

Mary Beth Caruso, Stokes urged FEMA to cut off availability<br />

of insurance through the National Flood Insurance Program<br />

to Illinois property owners behind the Sny unless the levee<br />

height is reduced.<br />

“It’s time to crack down,” he said.<br />

Local farmer Nancy Guyton agreed. Guyton and her husband<br />

grow corn and soybeans on 1,500 acres in the flood plain of<br />

Pike County, Missouri, directly across from the Sny. She said<br />

the too-tall Illinois levee means more significant damage to<br />

the family farm as the murky and often-toxic water sticks<br />

around longer during a flood.<br />

“It’s just a real mess and FEMA can do something about it,”<br />

Guyton said. “They’re dragging their heels. They should have<br />

taken care of this matter several years ago.”<br />

Maryland Board Votes Against Natural<br />

Gas Pipeline Project By Brian Witte<br />

ANNAPOLIS, Md. (AP) — A board of<br />

high-ranking Maryland officials on Wednesday,<br />

Jan. 2, rejected a proposed pipeline<br />

across the western part of the state that<br />

would carry natural gas produced in Pennsylvania<br />

to West Virginia.<br />

The Board of Public Works voted 3-0 against<br />

an easement for TransCanada’s pipeline. It<br />

would run under the Potomac River near<br />

Hanover, Md., and extend about 3 miles<br />

(4.83 kilometers) from Columbia Gas’ network<br />

in Pennsylvania to Mountaineer Gas’<br />

distribution system in West Virginia.<br />

Comptroller Peter Franchot, a Democrat, cited<br />

testimony that the pipeline could bring<br />

Maryland environmental problems without<br />

economic benefits. The board also includes<br />

Maryland Gov. Larry Hogan, a Republican,<br />

and Treasurer Nancy Kopp, a Democrat.<br />

Gov. Larry Hogan to reject the project. The bottom line reads: “No Potomac Pipeline.” A board of high-ranking Maryland officials rejected the pipeline<br />

Wednesday, Jan. 2, <strong>2019</strong>, that would carry natural gas produced in Pennsylvania to West Virginia. (AP Photo/Brian Witte, File)<br />

noted that Maryland approved a law, which Hogan signed in<br />

2017, to ban the hydraulic fracturing drilling process known<br />

as fracking in Maryland. The process is used to extract natural<br />

gas. Maryland was the first state where a legislature voted<br />

to bar the practice that actually has natural gas reserves.<br />

“Given that Maryland has banned fracking, it defies our<br />

state’s existing energy policy to bring the same public health<br />

risks to our residents by way of a pipeline,” the letter said.<br />

“Moreover, enabling fossil fuel production runs counter to<br />

our state’s goals of increasing renewable energy production.”<br />

The letter, which was sent the week of the meeting, also noted<br />

that the pipeline would affect at least 10 wetlands and 19<br />

streams, in addition to the Potomac River.<br />

While the board delayed a vote on the easement at its last<br />

meeting, Hogan said the unanimous vote would have happened<br />

without the letter from lawmakers.<br />

“It had nothing to do with any letter from the legislature,”<br />

Hogan said at the Jan. 2 board meeting.<br />

Anne Havemann, an attorney for Chesapeake Climate Action<br />

Network, said she hopes the board’s vote marks an end to<br />

the proposal.<br />

“We’ll see if (the Federal Energy Regulatory Commission)<br />

gets involved or the courts get involved, but for now it’s a<br />

welcome delay and we hope a permanent end to this pipeline,”<br />

Havemann said shortly after the vote.<br />

DODGEVILLE, Wis. (AP) — Residents in a rural Wisconsin<br />

county are split over a Chicago developer’s plan to work<br />

with two Wisconsin utilities to build a solar farm that would<br />

include more than 1 million solar panels.<br />

The Wisconsin State Journal reports that the Badger Hollow<br />

Solar Farm proposed by Invenergy would cover 2,700 acres in<br />

Iowa County and could power more than 70,000 homes. The<br />

project is seeking a permit from the Wisconsin Public Service<br />

Commission.<br />

Ken Wunderlin, a southwest Wisconsin farmer, said he<br />

agreed to have part of the solar farm on his land because<br />

it’s a good financial move. He believes it’s also a chance to<br />

get involved in a more environmentally friendly source of<br />

energy.<br />

“I’m a firm believer in the science on global warming,” he<br />

said. “We need to be taking steps to get away from coalfired<br />

power. This is my small opportunity to be a participant.”<br />

Renewable energy advocates have hailed it as a way for utilities<br />

to produce low-cost, clean energy within the state while<br />

providing some $1.8 million a year in rents for hard-pressed<br />

sharecroppers like Wunderlin.<br />

“We think of it as a complete win for the state of Wisconsin,”<br />

said Michael Vickerman, policy director for Renew<br />

Wisconsin. “We’re talking about renewable generation<br />

completely located within the state of Wisconsin. It is clean.<br />

It is quiet. It yields a great deal of financial benefits to the<br />

landowners and the surrounding communities.”<br />

But not everyone in Iowa County is welcoming the development.<br />

Richard Jinkins, a southwest farmer who lives just east of<br />

Wunderlin’s land on a 400-acre farm, said he’s worried that<br />

the farm will destroy the area’s scenic beauty, take up valuable<br />

farmland and cause the county’s 23,687 population to<br />

drop.<br />

Jinkins, along with two other nearby farmers, are leading the<br />

charge against the project as it goes through the permitting<br />

process with the Wisconsin Public Service Commission.<br />

“In the best case (it’s) going to make a solar panel wasteland<br />

where nobody’s going to live,” said Jinkins, a computer programmer<br />

who also raises cash crops. “It’s not going to be the<br />

Driftless area. It’s going to be the utility district of southwest<br />

Wisconsin.”<br />

North Dakota Bill Seeks to Discourage<br />

Pipeline Tampering<br />

BISMARCK, N.D. (AP) — A North Dakota legislator wants to<br />

increase the legal consequences for people who tamper with<br />

pipelines and any groups that help them, following a 2016<br />

pipeline protest that shut down oil flow for several hours.<br />

Republican Sen. Janne Myrdal of Edinburg is sponsoring the<br />

bill, The Bismarck Tribune reported.<br />

The legislation would more clearly define that it’s illegal to<br />

damage energy facilities and other critical infrastructure,<br />

such as refineries, electrical power generating facilities or<br />

natural gas processing plants.<br />

It also would increase maximum fines from $10,000 to<br />

$100,000 if an organization is found to have conspired with<br />

individuals who tamper with infrastructure.<br />

The bill wouldn’t prevent the “lawful assembly and peaceful<br />

and orderly petition for the redress of grievances.”<br />

“We worked hard on it to make sure that no First Amendment<br />

rights are trampled on whatsoever in this bill,” Myrdal<br />

said.<br />

Myrdal said the bill was inspired by the October 2016 pipeline<br />

protest involving TransCanada’s Keystone Pipeline, when<br />

activists turned an emergency valve and shut down oil flow.<br />

Seattle resident Michael Eric Foster, who served jail time for<br />

turning the pipeline valve during the protest, said a more<br />

stringent law wouldn’t have stopped him.<br />

“What I did, I did to protect my family because everything<br />

else is failing. I owe it to my family tree and yours to do<br />

whatever we can think of to stop destroying this place for<br />

our kids,” Foster said.<br />

Foster said the bill is an attempt to “silence and intimidate<br />

and harass people who are looking out for the public good.”<br />

Masonry Gives Construction Students<br />

Hands-On Training By Andrew Wind | Waterloo-Cedar Falls Courier<br />

WATERLOO, Iowa (AP) — Students in Wayne Lidtke’s sustainable<br />

construction and design class have learned about house<br />

building by doing it.<br />

They’ve framed walls, hung drywall, installed windows and<br />

doors, and done minimal wiring while building small scale<br />

houses at the Waterloo Career Center. The students will be<br />

working on some other skills, like roofing, in the Waterloo<br />

Community Schools’ program before the semester is over, the<br />

Waterloo-Cedar Falls Courier reported.<br />

Though, the nine high schoolers put down their hammers<br />

and picked up trowels. Iowa Masonry Institute members<br />

taught them lessons on mixing mortar and building a number<br />

of structures with cinder block and brick.<br />

Their task was to construct a pier. The column-like structure<br />

can support a beam in a building, an overhang on an entryway<br />

or have a more decorative use at the end of a driveway.<br />

Students shoveled mortar out of wheelbarrows onto plywood<br />

platforms. They scooped up the substance with their<br />

trowels, depositing it on the edges of a pair of cinder blocks<br />

before adding another layer of blocks.<br />

“You put a lot of mortar there so you have a lot of contact,<br />

just so in a couple years it doesn’t fall apart,” said Hunter<br />

Pierce, a West High School senior.<br />

Chris Busch, overseeing the students’ efforts, emphasized the<br />

importance of getting the right amount of mortar between<br />

the blocks.<br />

“That joint is an integral part of the unit,” noted the Marshalltown-based<br />

Bricklayers & Allied Craftworkers union<br />

training director. Ideally, he said, the mortar level will be<br />

about three-eighths of an inch.<br />

Without the right amount, “it’ll start to lose considerable<br />

integrity,” said Busch. “Three-eighths is kind of that sweet<br />

spot.”<br />

Students were building the piers five blocks high. “Then,<br />

they’re going to veneer it with brick,” he explained.<br />

and 80 YEARS<br />






As one of the students got several blocks high, Busch offered<br />

a bit of advice: “You can use your level to check that, check<br />

for level (horizontally) and plumb (vertically)” to ensure<br />

everything is straight and level.<br />

“It’s fun, it’s something to do,” said West High junior Nathan<br />

Elliott, of learning the skill. “Better than sitting in there on a<br />

computer. I like the hands-on stuff.”<br />

Pierce also likes learning this way and said he would consider<br />

working in construction.<br />

Those are the sorts of responses Busch hopes for from his<br />

training sessions at schools.<br />

“This is basically part of our recruitment,” he said. Students<br />

started with basics like learning how to spread mortar, lay<br />

brick and use a level. They also built a low wall earlier.<br />

Busch doesn’t expect everyone in the class to end up as a<br />

bricklayer. But bringing the program into schools is important<br />

to finding the next generation of workers — and the<br />

amount of time they’ve had at the career center only helps.<br />

“This is great having a whole week in here to present masonry<br />

to kids,” he said.<br />

Reinventing Fire Detection in Industrial<br />

Warehouses<br />

The cost of a fire in a warehouse goes far beyond the loss<br />

of the building and goods. The consequential loss caused by<br />

downtime, operation interruption, business reputation and<br />

goodwill can be significant.<br />

Modern goods also tend to have increased flammability, in<br />

addition to the presence of large amounts of packing materials<br />

such as plastics, cardboard, wooden crates and pallets.<br />

There are various possible ignition sources in warehouses including<br />

smoking, lighting, electrical equipment and heaters.<br />

Although sprinklers are typically installed in warehouses, the<br />

lack of an appropriate early warning smoke detection system<br />

can not only compromise the safety of the facility but also<br />

that of adjacent buildings.<br />

Fortunately, protecting life and inventory is much easier for<br />

even the largest warehouses as aspirating smoke detection<br />

(ASD) technology becomes more widely adopted. The process<br />

draws in air samples through durable piping to detectors and<br />

tests it using sophisticated laser-based technology, imaging,<br />

and photodiodes. Far from new, the core technology<br />

has been used for decades in sensitive applications such as<br />

cleanrooms and data centers where early smoke detection is<br />

critical.<br />

ily diluted. This makes detection difficult for conventional<br />

detection technologies where smoke must build up to certain<br />

levels before the alarm sounds. Furthermore, before sprinklers<br />

are triggered, sufficient heat needs to be generated by<br />

the fire — by which time, it is well underway.<br />

Because of these concerns, traditional spot smoke detectors<br />

are usually considered unsuitable for warehouses with high<br />

ceilings. The installation, wiring, testing, and maintenance of<br />

such spot detectors make them inconvenient and costly.<br />

For instance, regularly testing the smoke detectors requires<br />

having an inspector introduce smoke into the devices. This<br />

requires safely lifting the inspector to the level of the detector<br />

on a scissor lift, cherry picker, or other access equipment,<br />

which adds to inspection costs. Maintaining and repairing<br />

the smoke detectors is similarly costly.<br />

Compared to traditional spot smoke detectors and other<br />

technologies, this approach dramatically improves warehouse<br />

facility safety by detecting smoke at the earliest possible<br />

stage via numerous sampling points, while reducing false<br />

alarms and maintenance.<br />

Industrial-Sized Smoke Detection Challenges<br />

Warehouses come in a wide range of sizes and contain a wider<br />

range of goods. Most large warehouses have high ceilings<br />

of over 40 ft. (12 m), with some modern automated high rack<br />

storage facilities having ceiling heights over 130 ft. (40 m).<br />


The situation is even more challenging in facilities that<br />

operate 24/7, where maintenance is only allowed during a<br />

planned maintenance period.<br />

Linear heat cables and flame detectors are sometimes suggested<br />

offered as a solution and might be tempting from a<br />

maintenance point of view. However, their detection point<br />

(i.e. the flaming stage of fire) is too late to be truly considered<br />

as early warning or adequate detection.<br />

Optimizing Warehouse Smoke Detection<br />

The problem is that in these conditions any smoke is heav-<br />

Instead, as an alternative, ASD technology is a more effective,<br />

early detection option that does not require physical<br />

maintenance to access warehouse ceiling areas above high<br />

bay racks.<br />

Because of such flexibility, ASD smoke detection accommodates<br />

irregular ceiling structures. Moreover, the technology<br />

is not affected by forklifts, robotic gantries, and internal<br />

business operations. Finally, it can even provide detection<br />

within storage racks for the fastest possible response to a fire<br />

threat.<br />

As an example, one system, called VESDA-E VEU, by Xtralis,<br />

a global provider of aspirating fire detection equipment,<br />

draws air samples in a continuous process through holes in<br />

long runs of durable industrial pipe mounted along the walls<br />

and ceiling.<br />

While some ASD products use an LED light source and one<br />

or more photo receivers, the VEU utilizes a flair detection<br />

chamber that uses a short wavelength laser, a CMOS imager,<br />

and multiple photodiodes.<br />

Direct imaging of the sampled particles using the CMOS<br />

camera allows data regarding its size, color and shape to be<br />

derived. Additional data from five photodiodes allows measurement<br />

of light scatter in different directions.<br />

With more detailed information to analyze, the unit is able<br />

to differentiate smoke from other factors that could cause<br />

disruptive false alarms. For warehouse environments where<br />

airborne dust particles may also be present, which can be<br />

confused as smoke by some systems, the unit’s dust rejection<br />

and data analytics minimize nuisance alarms by at least 3<br />

times compared to similar technologies.<br />

Compared to even other aspirating technologies, the system<br />

significantly saves on maintenance costs by allowing long<br />

pipe runs up to 1,310 ft. (400 m) and branched pipe networks<br />

up to 2,625 ft. (800 m) to extend detector coverage. This<br />

reduces the number of detectors required to protect a single<br />

fire zone in a warehouse facility.<br />

Unique Warehouse Challenges<br />

Certain types of warehouses in difficult environments may<br />

still require a high level of fire protection, while posing<br />

unique challenges to smoke detection systems.<br />

Freezers & Refrigerated Storage<br />

While most warehouses with freezers or refrigerated storage<br />

have some form of automatic doors or plastic barrier curtains<br />

to limit warm air ingress, it is inevitable that warm air will<br />

enter the room. This often creates condensation within the<br />

room, which causes icing on ceiling-mounted equipment and<br />

structures close to the entry points.<br />

Even though ASD technology is generally accepted as the<br />

best solution for refrigerated storage facilities, there are<br />

some typical problems associated with its application in such<br />

situations.<br />

Over time, ASD sampling points and pipe within the sub-zero<br />

area can become blocked causing air flow issues and inoperative<br />

detection of smoke. In some instances, the only solution<br />

is to remove the iced up section of the ASD pipe network<br />

and fit a new pipe.<br />

To combat this issue, some providers offer a unique sampling<br />

arrangement that is specifically designed for refrigerated<br />

storage facilities.<br />

For example, Xtralis enables ASD air sampling pipe to be<br />

installed, inspected and maintained outside the refrigerated<br />

environment (i.e. within roof space). This makes it less prone<br />

to blockage due to icing, easier to inspect, and provides a<br />

more robust, longer lasting installation.<br />

Dusty Warehouses<br />

Certain warehouses are very dusty or highly contaminated<br />

environments such that the performance, longevity and<br />

maintenance of the detection equipment are a real concern.<br />

For these environments, ASD systems exist that are design to<br />

withstand the harsh environments in industrial applications,<br />

have superior dust filtration and are enclosed in NEMA 4<br />

equivalent enclosures.<br />

The Xtralis’ VESDA VLI system, for example, comes in an<br />

International Protection Marking IP66 enclosure that provides<br />

total protection against the ingress of dust and strong<br />

water jets. The unit also is designed with a patented intelligent<br />

filter that significantly reduces the amount of contaminants<br />

entering the detector. An integral secondary filter and<br />

sub-sampling probe also rejects larger dust particles, which<br />

further safeguards against nuisance alarms and extends<br />

detector life.<br />

Protecting the Warehouse Bottom Line<br />

Some managers of warehouse facilities may be inclined to<br />

use spot smoke detectors or other traditional devices because<br />

of their familiarity with such systems.<br />

However, those who take advantage of the superior capabilities<br />

of ASD systems will protect lives and inventory to a degree<br />

not previously possible in warehouse settings. This level<br />

of protection will also prevent serious supply chain disruption<br />

as well as liability and litigation in worst-case scenarios.<br />

Michigan Roadwork to See Increased<br />

Risks, Costs in Winter By Shawn D. Lewis | The Detroit News<br />

DETROIT (AP) — The pushing of Michigan’s roadwork into<br />

the colder months comes with great costs and risks for two<br />

of the area’s biggest projects.<br />

MacDonald said the cost for heating and enclosing concrete<br />

pavement is approximately 30 to 50 percent of the cost of<br />

the material and labor, “depending on a number of factors.”<br />

Work laying concrete has continued on Interstate 696 in<br />

Macomb County and Interstate 75 in Wayne County despite<br />

temperatures below or at 40 degrees, which, according to<br />

the American Concrete Institute, is the temperature for<br />

which measures to prevent freezing must be addressed.<br />

Costly precautions must be in place, including protecting<br />

fresh concrete from freezing by placing heaters along a<br />

route to ensure the concrete will take.<br />

“Nobody wants to build roads in the winter,” said Kevin<br />

MacDonald, a principal engineer with Minnesota-based Beton<br />

Consulting Engineers.<br />

In other words, he said, for every dollar spent on a road project<br />

conducted in July, it will cost between $1.30 and $1.50 in<br />

the winter.<br />

“Modern highway construction in cold, wet climates requires<br />

highly durable, as well as high-strength concrete,” he told<br />

The Detroit News. “This can be achieved in cold weather, so<br />

long as precautions are taken to ensure that the concrete has<br />

adequate strength.”<br />

But MacDonald noted taxpayers usually are not footing the<br />

bill for the higher costs.<br />

“Typically, these types of costs fall into means and methods<br />

over the contractor,” he said. “As such, the contractor will<br />

bear the cost.”<br />

A Michigan contractor working on one of the major road<br />

projects said his employees are using necessary precautions,<br />

and they are being closely monitored by the Michigan Department<br />

of Transportation to minimize the risk.<br />

News, Robin Buckson, File)<br />

Joe Goodall, vice president of Dan’s Excavating Inc. in Shelby<br />

Township, which is working on the I-75 project, said yes, contractors<br />

are working to prevent the ground from freezing.<br />

Goodall said workers are “covering the concrete when temperatures<br />

look to be dropping below freezing overnight or<br />

throughout the following days. The specifications for cold<br />

weather protection are being met on the project.”<br />

the importance of water treatment?<br />

They also running heaters on the ground to keep it from<br />

freezing, he said.<br />

“We are keeping the concrete within the specifications for<br />

cold weather paving by any means needed,” Goodall said.<br />

NEWS<br />

The construction work is happening later in the season<br />

because the projects were delayed in September when the<br />

Michigan Infrastructure and Transportation Association<br />

instituted a work stoppage after multiple failed attempts to<br />

bargain a new contract with the Operating Engineers Local<br />

324. A prior, five-year deal expired in June.<br />

The construction rift prompted the shutdown or partial halt<br />

of 89 Michigan Department of Transportation projects and<br />

75 local projects.<br />

“We are bound by contract with MDOT to complete the project<br />

in a time frame, with the lockout and inclement weather<br />

after the lockout, we are continuing to complete the project<br />

in a timely manner.”<br />

MDOT spokesman Jeff Cranson said state inspectors perform<br />

quality assurance on all contractor efforts throughout a<br />

project.<br />

“So among other things, the inspectors will ensure the heating<br />

and housing is correct,” he said. “Ultimately, the contractor<br />

is responsible for the work completed, and a job is not<br />

accepted until MDOT engineers are confident in the quality.”<br />

And so far, Operating Engineers 324 spokesman Dan McKernan<br />

said he has not heard any complaints from contractors<br />

about corners being cut to get the jobs done.<br />

“Certainly, there is frustration from the workers for having<br />

to work through the winter when it didn’t have to be<br />

this way,” McKernan said. “But I talked to the agent who<br />

oversees the road workers, and there haven’t been any complaints.<br />

At the end of the day, MDOT oversees everything,<br />

and they are very strict.”<br />

The American Concrete Institute recommends specific measures<br />

in its “Guide to Cold Weather Concreting,” noting that<br />

“the necessary degree of protection increases as the ambient<br />

temperature decreases.”<br />

Cold weather concreting “results in extra costs because of<br />

potentially lower worker productivity and additional needed<br />

products such as insulating blankets, tarping and heaters.”<br />

But it adds that these measures also most likely will allow a<br />

project to stay on schedule.<br />

Detroit averages highs of 36.1 degrees and lows of 24.1<br />

degrees in December, according to date from the National<br />

Weather Service in White Lake Township.<br />

Daniel DeGraaf, executive director of the Michigan Concrete<br />

Association, said placing heaters is a major element of<br />

keeping the ground warm. A hydronic heater is used to heat<br />

frozen ground or concrete surfaces by pumping heated fluid<br />

through closed-circulation tubing and a heat exchanger.<br />

“The ground cannot be frozen when building a road on top<br />

of it,” he said. “It can be very expensive.”<br />

He presented an analogy.<br />

Blower Wheels<br />

V Belts<br />

Controls<br />

And More<br />

But Cranson acknowledged risks when concrete is worked on<br />

in the winter.<br />

He released details that noted: “The top couple inches<br />

(estimated) of the concrete below the exposed surface could<br />

potentially act as a sacrificial layer, protecting the inner concrete<br />

mass from frost-related structural damage. But, if not<br />

protected from the cold weather exposure, this top exposed<br />

surface could undergo irreversible damage as it freezes. Over<br />

time, this damaged concrete surface will erode and scale<br />

away, ultimately resulting in loss of the pavement surface.”<br />

Additionally, the details noted, “Placing concrete pavement<br />

on a frozen base could result in significant loss in structural<br />

support as the base begins to thaw in the spring. As the base<br />

freezes, the moisture within it will expand, thus, causing the<br />

base to heave up (water expands approximately nine percent<br />

in volume as it freezes). When the base thaws, it returns to<br />

its original elevation. This will, in turn, take the pavement<br />

downward with it.”<br />

Cranson summed up the lengths being taken to ensure quality<br />

work on roads during the winter by saying: “Contractors<br />

and the MDOT engineers overseeing their work continue<br />

to work very hard to ensure a commitment to quality while<br />

they also work as quickly as possible to make travel lanes<br />

accessible to the public.<br />

“It is a difficult balancing act in ideal conditions, let alone<br />

in inclement weather. Please keep in mind that the people<br />

fixing and building our roads are our sisters, brothers, friends<br />

and neighbors.”<br />

“Imagine running a furnace with the doors and windows<br />

wide open,” he said. “Not only do they have to heat the<br />

ground, but you can’t go as far with the work as you can on<br />

a fall day because you’re limited by how far the equipment<br />

can stretch.”<br />

Meanwhile, Cranson said state inspectors will hold contractors<br />

accountable for the quality of the concrete.<br />

“All materials must meet specifications,” Cranson said.<br />

“Inspection to ensure specification compliance; and enforcement<br />

based on significant research and testing.”<br />

New Mexico May Reconsider Decision<br />

on More Natural Gas Wells By Morgan Lee<br />

SANTA FE, N.M. (AP) — New Mexico oilfield regulators<br />

announced Friday, Jan. 4, that they may revisit a decision to<br />

ease restrictions on natural gas well locations for a Texas-based<br />

company operating in the northwest corner of the<br />

state.<br />

The announcement came as state oversight of wells shifts<br />

to the Democratic administration of Gov. Michelle Lujan<br />

Grisham.<br />

The state’s Oil Conservation Commission scheduled a public<br />

meeting the following week regarding the approved application<br />

from Hilcorp Energy to increase potential well density in<br />

the San Juan Basin area from four wells to eight per 320-acre<br />

tract, or about half a square mile (1.2 square kilometers).<br />

Environmentalists estimate the density decision could concentrate<br />

patterns of oil well development across hundreds of<br />

square miles (square kilometers) of territory.<br />

In a statement Jan. 4, Hilcorp said it would defend the state’s<br />

ruling last year on well densities and highlighted the related<br />

opportunity for new jobs and investments in an economically<br />

depressed region of the state.<br />

“Hilcorp prevailed in this matter by presenting a scientifically<br />

sound case in accordance with all laws and regulations,” it<br />

said.<br />

Hilcorp has said longstanding density limits have prevented<br />

the company from tapping more of a formation called the<br />

Blanco-Mesaverde gas pool.<br />

The approval of the company’s application to increase well<br />

densities late last year prompted an outcry from conservationists<br />

and a rebuke from the state’s independently elected<br />

land commissioner who left office Dec. 31.<br />

Upon taking office last month, Democratic Land Commissioner<br />

Stephanie Garcia Richard urged the state to take up her<br />

agency’s request for an appeal that was rejected by oilfield<br />

regulators as termed-out Republican Gov. Susana Martinez<br />

left office on Dec. 31.<br />

“It is imperative that we make a decision in the region that<br />

ensures long-term sustainability and production that is fair to<br />

every producer in the state,” Garcia Richard said in a statement<br />

Jan. 4.<br />

The State Land Office oversees 14,000 square miles (36,000<br />

square kilometers) of land and additional underground<br />

resources that are used to help fund schools, universities,<br />

hospitals and other public institutions.<br />

The membership of the Oil Conservation Commission is determined<br />

by the governor, a Cabinet secretary and the state<br />

land commissioner.<br />

New Mexico’s first female state land commissioner, Stephanie Garcia Richard,<br />

speaks after taking the oath of office on Jan. 1, <strong>2019</strong>, at the state Capitol<br />

in Santa Fe, N.M. Women including newly inaugurated Gov. Michelle<br />

Lujan Grisham helped Democrats consolidate control over all statewide<br />

offices and New Mexico’s congressional delegation in November elections.<br />

projects and other development across millions of acres of state trust land.<br />

The San Juan Citizens Alliance, an environmental advocacy<br />

group, also has sought a rehearing of the well-density<br />

decision, arguing that it was unfairly shut out of application<br />

proceedings where it hoped to provide testimony about<br />

public-health and environmental impacts.<br />

Erik Schlenker-Goodrich, an attorney for the Alliance, called<br />

the planned meeting a positive development.<br />

“There’s an opportunity to rebuild the credibility of the Oil<br />

Conservation Commission and to ensure that the public has a<br />

voice in oil and gas regulation,” he said.<br />

cooling<br />

systems<br />

designed to save<br />

both water and energy<br />

at new facility<br />

Behind the scenes of the most cutting-edge genetic science<br />

lies the work and expertise of companies like New England<br />

BioLabs, Inc. based in Ipswich, Mass.<br />

Since the 1970s, New England BioLabs has provided enzymes<br />

for use in molecular biology research and clinical trials, serving<br />

a network of customers internationally.<br />

The enzymes produced at New England BioLabs are used<br />

in applications like cloning, DNA modification and protein<br />

analysis — applications which are highly precise, requiring<br />

Plans are reviewed and Decco riggers<br />

complete cooling tower installations<br />

at New England BioLab’s new facility.<br />

An EVAPCO cooling module is lifted into place.<br />

components that are predictable, repeatable and of the<br />

highest quality.<br />

To better serve the ever evolving needs of their customers,<br />

New England BioLabs (NEB) has recently completed the<br />

construction of a 40,000 square foot cleanroom production<br />

facility in Rowley, Mass.<br />

The Right Construction Team<br />

Pulling it all together was the project management firm,<br />

Columbia Construction Company, a Boston-based company<br />

with over 90 years’ experience in multiple sectors: academic,<br />

life sciences, corporate, healthcare and hospitality.<br />

Neal Swain, project manager, explained, “Columbia was<br />

involved with the construction of NEB’s new facility for the<br />

entire process, from design review to final commissioning.”<br />

Columbia worked with AHA Consulting Engineers, Inc.<br />

(AHA) for building’s engineering infrastructure, including<br />

the plant’s process cooling mechanical system. AHA’s clients<br />

include companies such as Vertex, Takeda, Merck, and NEB<br />

itself, as AHA served as the design engineers for its main<br />

facility.<br />

As is customary in the industry, AHA worked with suppliers<br />

to find the right equipment to meet the NEB’s specific<br />

requirements. Manufacturer’s rep firm, Fluid Equipment<br />

Solutions of New England (FES), provided technical assistance<br />

for the cooling system at this new facility.<br />

Tight Tolerances for Cooling<br />

Accurate and robust temperature control of the equipment<br />

and environment is critical to the success of the tightly-controlled<br />

manufacturing processes.<br />

A key component of the cooling system that meets the<br />

stringent cooling needs at NEB’s facility is its fluid cooler,<br />

a 1.6 million BTU closed circuit cooling tower designed<br />

to provide cooling to process water for a wide variety of<br />

sophisticated plant processes.<br />

“The fluid cooler provides condenser water to one side of<br />

a heat exchanger,” said Thomas Joyner, partner, and AHA<br />

project manager. “The process water on the other side of<br />

the heat exchanger serves several pieces of plant equipment<br />

as well as a process chiller to provide chilled water for<br />

manufacturing.”<br />

For such a large, yet critical piece of the cooling puzzle,<br />

AHA considered several options for the fluid cooler. With<br />

the rising cost of energy and concern about water consumption,<br />

the amount of electricity and water used was<br />

an additional factor in deciding which cooling system to<br />

specify.<br />

Ben McLaughlin, sales engineer at FES said, “We compared<br />

the performance of multiple evaporative fluid coolers in<br />

terms of meeting the required temperature as well as energy<br />

and water use.”<br />

(Continued on page 40)<br />

system.”<br />

This tight control is what gives NEB the level of utility savings<br />

as well as the consistency and predictability needed for their<br />

manufacturing processes.<br />

Eco-friendly Accessories<br />

The other key evaporative cooling system components are<br />

the water treatment, and the quiet fan, also selected by the<br />

design team. Although water treatment is necessary to maintain<br />

evaporative cooled equipment during wet operation,<br />

a substantial benefit to a primarily dry cooler is that scale<br />

cannot form when the unit is operating in dry operation.<br />

To prevent scale buildup or corrosion from deposits when<br />

water is evaporated in the cooler, the water must be treated.<br />

In order to maintain an environmentally friendly manufacturing<br />

facility, a non-chemical treatment system was provided<br />

for this evaporative water.<br />

Expert hands bring together the cooling tower assembly at New England<br />

BioLab’s new facility.<br />

After careful analysis, EVAPCO’s eco ATWB-H series hybrid<br />

fluid cooler was selected. The system is specifically designed<br />

to optimize both the evaporative (latent) and dry (sensible)<br />

modes of cooling simultaneously — combining the advantages<br />

of an evaporative cooler and a dry cooler into one unit.<br />

A Balancing Act<br />

McLaughlin explains, “There were three aspects of the fluid<br />

cooling system that were critical for this application. The first<br />

was the cooling tower’s wet and dry performance.”<br />

The hybrid fluid cooler has both wet and dry operation with<br />

the ability to handle full capacity in “dry mode” up to an<br />

ambient dry bulb temperature of 50oF. This reduces water<br />

consumption for every hour of operation below 50o when<br />

the water is turned off and the fan alone is doing all the<br />

cooling.<br />

“In addition to water savings, the five-horsepower spray<br />

pump is turned off during dry cooling, and that results in<br />

energy savings when compared to the standard fluid cooler<br />

using evaporative cooling only,” said McLaughlin. “So we<br />

have about 60 percent less water used and a 30 percent<br />

reduction in electricity consumption.”<br />

Process water first enters the dry coil which is outside the<br />

evaporative water spray stream. This coil serves to pre-cool<br />

the high-temperature water. The cooled water then enters<br />

the coil, just below the spray stream. Depending on the dry<br />

bulb temperature, the spray pump may be on or off.<br />

A key benefit of the dry coil, piped in series with the wet<br />

coil, is that the evaporation rate off of the wet coil is maximized<br />

because a significant portion of the heat load from<br />

the process has already been rejected by the dry coil before<br />

entering the wet coil. This means that water is always saved,<br />

even when spray pumps are required for full load.<br />

The additional dry coil also allows for reduced water vapor<br />

leaving the cooling tower, which happens because of<br />

efficient transfer of heat from the process water to the moist<br />

air leaving the cooling tower. Increasing the temperature of<br />

the air leaving the tower, without adding moisture, reduces<br />

its relative humidity from a saturated state (at 100 percent),<br />

which greatly reduces the visible plume.<br />

In order to get the most out of this hybrid system, the fan<br />

and spray pump operation are controlled to maximize<br />

savings. The SAGE® control system provided with the cooler<br />

plays a key role in optimizing water and energy savings.<br />

“The controller leverages outdoor or ambient conditions,”<br />

explained McLaughlin. “Specifically, the wet bulb and dry<br />

bulb temperatures are used to best meet load requirements<br />

while reducing water and energy consumption. This sophisticated<br />

operation is handled in stride by the SAGE control<br />

“We included the Pulse-Pure® non-chemical water treatment<br />

system with the fluid cooler,” McLaughlin explained. “This<br />

system uses a high-frequency electromagnetic pulse to take<br />

care of the corrosive or scale-forming solids that would otherwise<br />

concentrate on the cooler’s components when water<br />

evaporates. It also takes care of anything biological that<br />

we’re usually concerned with because it renders microorganisms<br />

incapable of reproduction.”<br />

In addition to reducing chemicals used on site, the unit itself<br />

produces less sound pollution. The super-low sound fan<br />

selected boasts a 9- to 16-decibel reduction in sound when<br />

compared to the standard fluid cooler fan.<br />

“The reduction in sound is concentrated in the low-frequency<br />

octave band, which travel further distances and penetrate<br />

structures,” explained McLaughlin, “so these are the fans<br />

specifically designed for applications that are sound-sensitive<br />

in nature.”<br />

With EVAPCO’s hybrid fluid cooler serving the manufacturing<br />

process, New England BioLabs’ new cleanroom production<br />

facility achieves both high-quality product and lower water<br />

and energy consumption.<br />

“We took the shell of a building and turned it into a 40,000<br />

square foot cleanroom production facility,” said Swain,<br />

“and the process cooling system assures utility savings while<br />

delivering predictable outcomes for NEB’s customers, both<br />

existing and those we expect to serve in the future.”<br />

Connecticut Taps Nuclear Plants to<br />

Generate Clean Energy<br />

HARTFORD, Conn. (AP) — Nuclear power plants in Connecticut<br />

and New Hampshire made the list of electricity producers<br />

selected Dec. 28 to generate the clean energy needed to<br />

help meet Connecticut’s goals for reducing greenhouse gas<br />

emissions.<br />

Department Energy and Environmental Protection Commissioner<br />

Robert Klee and Democratic Gov. Dannel P. Malloy<br />

announced the state also chose bids submitted from nine<br />

solar projects and one offshore wind project. Final regulatory<br />

approval of power contracts, which still need to be negotiated,<br />

are still required.<br />

“The selection of this diverse portfolio of zero-carbon resources<br />

ensures that Connecticut is doing its part to address<br />

climate change,” Klee said. A 2017 state law required DEEP’s<br />

commissioner to solicit proposals for up to 12 million megawatt-hours<br />

of clean energy annually to meet the state’s<br />

renewable energy goals.<br />

Virginia-based Dominion Energy had sought for months<br />

to have its Millstone Nuclear Power Station in Waterford,<br />

Connecticut, included in the clean energy procurement. Dominion<br />

had argued that the plant faced closure due to rising<br />

expenses and competition from natural gas.<br />

“We look forward to executing the contract with Connecticut’s<br />

utilities shortly,” he said.<br />

State regulators recently determined Millstone was at risk of<br />

early retirement, a move that ultimately allowed the plant to<br />

be part of DEEP’s clean energy auction.<br />

DEEP also selected nine solar projects, including three in<br />

Connecticut, four in Maine and two in New Hampshire.<br />

Additionally, DEEP announced plans to expand upon its June<br />

selection of 200 megawatts of energy generated by the Revolution<br />

Wind offshore project being developed by Rhode Island-based<br />

Deepwater Wind. DEEP said the state will procure<br />

an additional 100 megawatts of power from the wind farm,<br />

located in federal waters, about halfway between Montauk,<br />

N.Y., and Martha’s Vineyard, Mass.<br />

“Offshore wind is fast becoming a centerpiece of Connecticut’s<br />

renewable energy future,” said Jeffrey Grybowski, Co-<br />

CEO of Ørsted US Offshore Wind, which acquired Deepwater<br />

Wind in October. “We’re proud that our Revolution Wind<br />

project will now deliver even more clean energy to Connecticut<br />

communities.”<br />

A top Dominion executive said Dec. 28 that the company is<br />

pleased Millstone is part of the portfolio. DEEP selected a 10-<br />

year bid for about 50 percent of the entire nuclear facility’s<br />

output. DEEP also selected a bid from the Seabrook Nuclear<br />

Power Plant in New Hampshire.<br />

“DEEP’s decision is good news for Connecticut’s economy and<br />

the environment,” said Paul Koonce, EVP, president and CEO<br />

of power generation at Dominion Energy. He said Dominion’s<br />

“zero carbon offer brings at least $670 million in net<br />

benefits to Connecticut customer” and “welcome holiday<br />

news” for the power plant’s 1,500 employees.<br />

LOg-IN To<br />


BISMARCK, N.D. (AP) — The developer of the Dakota Access<br />

oil pipeline missed a year-end deadline to plant thousands<br />

of trees along the pipeline corridor in North Dakota, but<br />

the company said it was still complying with a settlement of<br />

allegations it violated state rules during construction.<br />

Texas-based Energy Transfer Partners, which built the $3.8<br />

billion pipeline that’s now moving North Dakota oil to<br />

Illinois, is falling back on a provision of the September 2017<br />

agreement. The provision provides more time should the<br />

company run into problems providing 20,000 trees to county<br />

soil conservation districts along the pipeline’s 359-mile<br />

(578-kilometer) route across North Dakota.<br />

The deal with North Dakota’s Public Service Commission<br />

settled allegations that ETP removed too many trees in some<br />

areas and that it improperly handled a pipeline route change<br />

after discovering Native American artifacts. The artifacts<br />

were not disturbed.<br />

The agreement required the company to replant trees and<br />

shrubs at a higher ratio in the disputed areas, along with an<br />

additional 20,000 trees along the entire route. ETP filed documents<br />

in October detailing efforts by a contractor to plant<br />

141,000 trees and shrubs, but the PSC asked the company<br />

a month later to provide more documentation that it had<br />

complied with all settlement terms.<br />

tricts due to several factors, including equipment and staffing<br />

issues, difficulties finding willing landowners and poor<br />

planting conditions, according to Perennial Environmental<br />

Services, which ETP hired to handle the work.<br />

A soil conservation district in one of the seven counties<br />

refused to participate at all because it didn’t feel any of the<br />

15 tree species identified in the settlement agreement were<br />

suitable for the county.<br />

The agreement allows for the work to continue into <strong>2019</strong> if<br />

there are problems with the tree supply “or other market<br />

conditions.” Soil conservation districts in six counties have<br />

committed to planting about 16,800 more trees in <strong>2019</strong>, for<br />

a total of more than 25,500, according to Perennial Environmental<br />

Services.<br />

PSC officials weren’t available at press time for comment on<br />

whether the state thinks ETP is justified in prolonging the<br />

plantings into the new year.<br />

Under the agreement, ETP also was directed to develop an<br />

industry handbook on properly handling pipeline route adjustments<br />

and to conduct training. In return, the PSC didn’t<br />

require the company to admit wrongdoing and scrapped a<br />

proposed $15,000 penalty. The agency has the power to levy<br />

up to $200,000 in fines.<br />

Auto-renewal of your annual membership is now available<br />

and easily managed from your phone or other device.<br />

What do I need to do?<br />

Company attorney Lawrence Bender recently submitted a<br />

report from contractor KC Harvey Environmental further detailing<br />

the replanting efforts in the disputed areas. He noted<br />

that in some areas where landowners refused trees, the trees<br />

were reallocated to other landowners “who had the space<br />

and desire to accommodate more plantings.”<br />

Bender in December detailed training that he said surpassed<br />

what was required during the Williston Basin Petroleum Conference<br />

in May, the North Dakota Petroleum Council annual<br />

meeting in September and the Colorado Oil and Gas Association<br />

annual meeting in November.<br />

Army Looks for a Few Good Robots,<br />

Sparks Industry Battle By Matt O’Brien<br />

CHELMSFORD, Mass. (AP) — The Army is looking for a few<br />

good robots. Not to fight — not yet, at least — but to help<br />

the men and women who do.<br />

These robots aren’t taking up arms, but the companies making<br />

them have waged a different kind of battle. At stake is a<br />

contract worth almost half a billion dollars for 3,000 backpack-sized<br />

robots that can defuse bombs and scout enemy<br />

positions. Competition for the work has spilled over into<br />

Congress and federal court.<br />

The project and others like it could someday help troops<br />

“look around the corner, over the next hillside and let the<br />

robot be in harm’s way and let the robot get shot,” said Paul<br />

Scharre, a military technology expert at the Center for a New<br />

American Security.<br />

The big fight over small robots opens a window into the<br />

intersection of technology and national defense and shows<br />

how fear that China could surpass the U.S. drives even small<br />

tech startups to play geopolitics to outmaneuver rivals. It also<br />

raises questions about whether defense technology should<br />

be sourced solely to American companies to avoid the risk of<br />

tampering by foreign adversaries.<br />

Regardless of which companies prevail, the competition<br />

foreshadows a future in which robots, which are already familiar<br />

military tools, become even more common. The Army’s<br />

immediate plans alone envision a new fleet of 5,000 ground<br />

robots of varying sizes and levels of autonomy. The Marines,<br />

Navy and Air Force are making similar investments.<br />

“My personal estimate is that robots will play a significant<br />

role in combat inside of a decade or a decade and a half,”<br />

the chief of the Army, Gen. Mark Milley, said in May at a<br />

Senate hearing where he appealed for more money to modernize<br />

the force.<br />

Milley warned that adversaries like China and Russia “are<br />

investing heavily and very quickly” in the use of aerial, sea<br />

and ground robots. And now, he added, “we are doing the<br />

same.”<br />

Such a shift will be a “huge game-changer for combat,” said<br />

Scharre, who credits Milley’s leadership for the push.<br />

The promise of such big Pentagon investments in robotics<br />

has been a boon for U.S. defense contractors and technology<br />

startups. But the situation is murkier for firms with foreign<br />

ties.<br />

Concerns that popular commercial drones made by Chinese<br />

company DJI could be vulnerable to spying led the Army to<br />

ban their use by soldiers in 2017. And in August, the Pentagon<br />

published a report that said China is conducting espionage<br />

to acquire foreign military technologies — sometimes<br />

by using students or researchers as “procurement agents and<br />

intermediaries.” At a December defense expo in Egypt, some<br />

U.S. firms spotted what they viewed as Chinese knock-offs of<br />

their robots.<br />

The China fears came to a head in a bitter competition<br />

between Israeli firm Roboteam and Massachusetts-based Endeavor<br />

Robotics over a series of major contracts to build the<br />

Army’s next generation of ground robots. Those machines<br />

will be designed to be smarter and easier to deploy than the<br />

remote-controlled rovers that have helped troops disable<br />

bombs for more than 15 years.<br />

The biggest contract — worth $429 million — calls for<br />

mass-producing 25-pound robots that are light, easily maneuverable<br />

and can be “carried by infantry for long distances<br />

A Centaur robot rests on a carpeted floor between desks at Endeavor Robotics in Chelmsford, Mass. The Army is looking for a few good robots. These<br />

robots won’t fight — at least, not yet. But they will be designed to help the men and women who do. The companies making them are waging a different<br />

kind of battle. At stake is a contract worth almost half a billion dollars for 3,000 backpack-sized robots that can defuse bombs and scout enemy positions.<br />

without taxing the soldier,” said Bryan McVeigh, project<br />

manager for force projection at the Army’s research and<br />

contracting center in Warren, Michigan.<br />

Other bulkier prototypes are tank-sized unmanned supply<br />

vehicles that have been tested in recent weeks in the rough<br />

and wintry terrain outside Fort Drum, New York.<br />

A third $100 million contract — won by Endeavor in late<br />

2017 — is for a midsized reconnaissance and bomb-disabling<br />

robot nicknamed the Centaur.<br />

The competition escalated into a legal fight when Roboteam<br />

accused Endeavor, a spinoff of iRobot, which makes Roomba<br />

vacuum cleaners, of dooming its prospects for those contracts<br />

by hiring a lobbying firm that spread false information<br />

to politicians about the Israeli firm’s Chinese investors.<br />

A federal judge dismissed Roboteam’s lawsuit in April.<br />

“They alleged that we had somehow defamed them,” said<br />

Endeavor CEO Sean Bielat, a former Marine who twice ran<br />

for Congress as a Republican. “What we had done was taken<br />

publicly available documents and presented them to members<br />

of Congress because we think there’s a reason to be concerned<br />

about Chinese influence on defense technologies.”<br />

The lobbying firm, Boston-based Sachem Strategies, circulated<br />

a memo to members of the House Armed Services Committee.<br />

Taking up Endeavor’s cause was Rep. Seth Moulton, a<br />

Massachusetts Democrat — and, like Bielat, a Marine veteran<br />

— who wrote a letter to a top military official in December<br />

2016 urging the Army to “examine the evidence of Chinese<br />

influence” before awarding the robot contracts.<br />

Six other lawmakers later raised similar concerns.<br />

Roboteam CEO Elad Levy declined to comment on the dispute<br />

but said the firm is still “working very closely with U.S.<br />

forces,” including the Air Force, and other countries. But it’s<br />

no longer in the running for the lucrative Army opportunities.<br />

Endeavor is. Looking something like a miniature forklift<br />

on tank treads, its prototype called the Scorpion has been<br />

zipping around a test track behind an office park in a Boston<br />

suburb.<br />

The only other finalist is just 20 miles away at the former<br />

Massachusetts headquarters of Foster-Miller, now a part of<br />

British defense contractor Qinetiq. The company did not<br />

respond to repeated requests for comment. The contract is<br />

expected to be awarded in early <strong>2019</strong>.<br />

Both Endeavor and Qinetiq have strong track records with<br />

the U.S. military, having supplied it with its earlier generation<br />

of ground robots such as Endeavor’s Packbot and Qinetiq’s<br />

Talon and Dragon Runner.<br />

After hiding the Scorpion behind a shroud at a recent Army<br />

conference, Bielat and engineers at Endeavor showed it for<br />

the first time publicly to The Associated Press in November.<br />

Using a touchscreen controller that taps into the machine’s<br />

multiple cameras, an engineer navigated it through tunnels,<br />

over a playground-like structure and through an icy pool of<br />

water, and used its grabber to pick up objects.<br />

It’s a smaller version of its predecessor, the Packbot, which<br />

was first used by U.S. troops in Afghanistan in 20<strong>02</strong> and later<br />

became one of soldiers’ essential tools for safely disabling<br />

improvised explosives in Iraq. Bielat said the newer Scorpion<br />

and Centaur robots are designed to be easier for the average<br />

soldier to use quickly without advanced technical training.<br />

“Their primary job is to be a rifle squad member,” Bielat said.<br />

“They don’t have time to mess with the robot. They’re going<br />

to demand greater levels of autonomy.”<br />

It will be a while, however, before any of these robots become<br />

fully autonomous. The Defense Department is cautious<br />

about developing battlefield machines that make their own<br />

decisions. That sets the U.S. apart from efforts by China and<br />

Russia to design artificially intelligent warfighting arsenals.<br />

A November report from the Congressional Research Service<br />

said that despite the Pentagon’s “insistence” that a human<br />

must always be in the loop, the military could soon feel compelled<br />

to develop fully autonomous systems if rivals do the<br />

same. Or, as with drones, humans will still pull the trigger,<br />

but a far-away robot will lob the bombs.<br />

Wireless connectivity enables remediation, home inspection, pest control<br />

and other pros to view moisture readings from a mobile device.<br />

The MR55 is a pin meter with a built-in library of 11 material<br />

groups: wood, drywall, concrete, brick, and other building<br />

materials. The user can tune the meter to the most appropriate<br />

test material to improve measurement accuracy. Professionals<br />

can also access a material group reference document<br />

from FLIR.com by using a smartphone device to scan a QR<br />

code on the back of the meter.<br />

Both the MR59 and MR55 were designed for professionals to<br />

improve work efficiency, inspect any location with ease, and<br />

access the most accurate moisture readings possible. Wireless<br />

connectivity in both devices offers a convenient way to<br />

view data from a mobile device with the FLIR Tools® Mobile<br />

App. This is useful when the meter’s display is out of view,<br />

such as when taking measurements on the ceiling or within<br />

a cabinet.<br />

The new moisture meters will be available for purchase in<br />

the United States beginning in mid-September through FLIR<br />

distributors. For more information, visit FLIR.com.<br />

Computer Scientists Study Security<br />

Threats to Smart Homes By Tamara Dietrich<br />

And you’re none the wiser — until you get home and discover<br />

your home’s been hacked. And burgled.<br />

This is just one scenario demonstrating one of many inherent<br />

flaws that computer scientists at the College of William and<br />

Mary discovered in internet-connected smart home devices<br />

during tests they conducted over the summer.<br />

This particular flaw allows hackers to attack a smart home’s<br />

low-security device — a light switch or thermostat, for instance<br />

— and use that access to attack a high-security device<br />

they could not otherwise access.<br />

It’s one example of what’s called lateral privilege escalation,<br />

and experts warn that such smart home hacks are easier than<br />

you might think. They can lead to all kinds of potential mischief,<br />

if not outright harm, from switching off your security<br />

system to cranking up your smart oven until it overheats and<br />

burns the house down.<br />

“The possibilities are limitless,” said Adwait Nadkarni, lead<br />

investigator and assistant professor of computer science.<br />

“There are so many devices in the home that affect your<br />

security, affect the integrity of your home.”<br />

Experts say that in just two years there will be 20 billion<br />

smart home products in use.<br />

William & Mary computer science associate professors Adwait Nadkarni and<br />

Denys Poshyvanyk and their students have identified security vulnerabilities<br />

in smart home devices. Weaknesses in the security of a Web-enabled light<br />

bulb could give hackers access to Web-enabled cameras and security devices,<br />

allowing them to be disabled. (Rob Ostermaier/The Daily Press via AP)<br />

WILLIAMSBURG, Va. (AP) — Say you’re on your laptop at<br />

Starbucks, minding your own business, when an acquaintance<br />

of yours across the room isn’t minding his.<br />

Unbeknownst to you, he’s using the same store Wi-Fi as you<br />

to conduct a virtual invasion of your smart home: accessing<br />

your light switch app and using it to disable your home’s<br />

security camera so real thieves can break in — or walk in, if<br />

he’s disabling the smart lock, too.<br />

“You can imagine the possible combinations of these kinds<br />

of attacks will obviously increase as we’ll have more interconnected<br />

devices,” said associate professor Denys Poshyvanyk.<br />

“At this point, it’s hard for us to imagine what else people<br />

will do.”<br />

Nadkarni and Poshyvanyk co-authored a paper on their work<br />

that they’ll present at the 9th annual ACM Conference on<br />

Data and Application Security and Privacy in Dallas in March.<br />

Student co-authors include Kaushal Kafle and Sunil Manandhar<br />

and post-doctoral fellow Kevin Moran.<br />

In the paper, they lay out the potential misuses of the computer<br />

routines or portions of code that control smart home<br />

products and offer 10 key findings with “serious security<br />

implications.”<br />

“The diversity of these products is staggering,” the paper<br />

states, “ranging from small physical devices with embedded<br />

computers such as smart locks and light bulbs to full-fledged<br />

appliances such as refrigerators and HVAC systems.”<br />

And the risks, it states, can be rather alarming.<br />

“Because many of these products are tied to the user’s security<br />

or privacy (e.g., door locks, cameras), it is important to<br />

understand the attack surface of such devices and platforms<br />

in order build practical defenses without sacrificing utility.”<br />

For their research, Nadkarni and Poshyvanyk focused on<br />

two of the most popular smart home platforms — Google<br />

(Continued on page 56)<br />

54 | Chief Engineer<br />

Volume 84 · Number 2 | 55

Techline<br />

Nest and Philips Hue — that implement home automation<br />

“routines.”<br />

Routines are the interactions between smart home devices<br />

and the apps that control them. They are becoming the heart<br />

of seamless home automation.<br />

According to the paper, there are two broad categories of<br />

routines: one that allows users to “chain together” a variety<br />

of devices using a third-party app interface, and one<br />

that uses a “centralized data store” as a sort of switchboard<br />

where devices and apps can communicate with each other<br />

over the internet.<br />

Both are intended to make smart home automation more<br />

seamless for the user, and both were found to be vulnerable,<br />

giving hackers the ability to attack all the internet-connected<br />

devices in the home.<br />

For the centralized data store platform, for instance, when<br />

you use your mobile app to communicate with a low-security<br />

device — say, a light switch — the device accesses your smart<br />

home using an authorization token.<br />

“Anybody can steal that access token,” Nadkarni said, and<br />

use it to, say, make your smart home think you’re inside and<br />

turn off the security camera.<br />

The scientists insist it’s not that hard.<br />

“You don’t need any specialized education,” said Poshyvanyk.<br />

‘You just need to know how to run certain programs.<br />

Even a high schooler could do that.”<br />

They blame the vulnerabilities on consumer demand and the<br />

headlong rush to meet it.<br />

“Manufacturers race to release these systems without having<br />

a good understanding of how they will be used in the wild,”<br />

Poshyvanyk said.<br />

After the researchers identified the security flaws, they contacted<br />

platform vendors Google and Philips and app developer<br />

and manufacturer TP Link to report what they found.<br />

TP Link fixed the flaw in its latest Kasa Switch light dimmer<br />

app, which prevents the type of theoretical lateral attack<br />

outlined earlier. Philips is expected to roll out a fix to its platform<br />

and Google is working to address vulnerabilities.<br />

But the issue is bigger than one company — it’s the industry<br />

overall that needs to get smarter.<br />

“We’re basically arguing that we need a systemic effort in<br />

terms of properly designing these systems with security in<br />

mind,” Poshyvanyk said.<br />

EVAPCO Water Saver Provides<br />

Pre-treatment for Evaporative Cooling<br />

Equipment<br />

EVAPCO Water Systems has introduced the Water Saver, a<br />

device that substantially reduces water use for evaporative<br />

cooling equipment — whether new, or as a retrofit.<br />

Just recently, an Indiana school with a 1,200-ton HVAC system<br />

reduced water consumption by 1.5 million gallons/year<br />

with the technology.<br />

Water Saver is a capacitive deionization pre-treatment<br />

system to improve the efficiency of heat transfer and water<br />

efficiency for evaporative cooling systems. The capacitive<br />

deionization technology reduces dissolved ion concentrations<br />

to lower makeup water conductivity prior to use in evaporative<br />

cooling systems. Dissolved ions are removed from makeup<br />

water as they are attracted to the charged capacitors.<br />

Water Saver improves water efficiency by increasing operating<br />

cycles of concentration; this reduces blowdown and the<br />

use of treatment chemicals. Water Saver lowers cost of ownership,<br />

provides a 75-90 percent recovery rate, and improves<br />

a facility’s LEED rating. The technology is available in nine<br />

different configurations.<br />

St. Cloud Wastewater Plant Fueled by<br />

Beer, Byproducts By Anna Haecherl | Saint Cloud Times<br />

ST. CLOUD, Minn. (AP) — Whenever you dump something<br />

down the drain, it goes to the city of St. Cloud’s NEW (Nutrients,<br />

Energy and Water) Recovery Facility, where nutrients<br />

are recovered, waste is treated, and clean water is sent back<br />

into the environment.<br />

But large-scale beverage producers — who have high-sugar<br />

waste filled with potential energy — get special treatment<br />

when it comes to the byproducts created at their facilities.<br />

“We can treat it in a different manner that uses a lot less<br />

electricity, and that we can use to make a fuel,” said Pat<br />

Shea, public services director for the city.<br />

Beverage producers have been bringing what Shea calls<br />

high-strength byproducts to the plant for two years, the<br />

Saint Cloud Times reported. For example, Shea said, a beverage<br />

company or brewery will brew a batch of product, and<br />

once it’s done, the company will clean its production lines<br />

and flush everything out to prepare equipment for the next<br />

batch.<br />

That first rinse will still have product in it, Shea said, and<br />

producers can either put it down the drain, or collect it and<br />

bring it to the NEW Recovery Facility.<br />

Shea said the facility has arrangements with Beaver Island<br />

Brewing, Viking Coca-Cola, Cold Spring Brewing and other<br />

local producers.<br />

“Anything we can do to reclaim this product, recover energy<br />

and use it to run the facility, the more efficient we are,” Shea<br />

said.<br />

High-strength byproducts — like expired soda or beer, residue<br />

left over from the brewing process, or a batch of product<br />

that just didn’t turn out right — are put into anaerobic<br />

digesters along with municipal solids from wastewater — like<br />

A large engine runs on biogas at the Wastewater Treatment Facility in St.<br />

Cloud, Minn. Whenever you dump something down the drain, it goes to<br />

the city of St. Cloud’s NEW (Nutrients, Energy and Water) Recovery Facility,<br />

where nutrients are recovered, waste is treated, and clean water is sent<br />

back into the environment. (Dave Schwarz/St. Cloud Times via AP)<br />

human waste, food waste, and solid residue from cleaning<br />

processes — to produce methane gas.<br />

“We take that high-strength waste and we put it into an<br />

anaerobic conditions, meaning without oxygen,” Shea said.<br />

“Then micro organisms that are in those digesters ... will<br />

consume that material for their respiration. It’s a biological<br />

process, and, as they use it for their processes, they create<br />

methane gas.”<br />

The gas is used to power an onsite generator or run boilers<br />

that heat the digesters converting the byproducts into<br />

methane.<br />

It’s a win-win, Shea said. Instead of dumping the waste and<br />

using more energy to have it treated at the plant, the byproducts<br />

are being used to power the NEW Recovery Facility.<br />

At Beaver Island Brewing, co-founder Nick Barth said waste<br />

wasn’t such a big issue when they first started at their downtown<br />

brewery. But when they opened their new facility in<br />

May 2017 near St. Cloud Regional Airport and started brewing<br />

at a scale four or five times greater, the decision to bring<br />

byproducts to the NEW Recovery Facility instead of putting<br />

them down the drain was an easy one.<br />

“That’s cool because we’re making energy for the city,” Barth<br />

said. “But what’s even cooler is that we’re drastically reducing<br />

our carbon footprint.”<br />

Barth said the brewery captures and harvests its yeast slurry<br />

and trub — a sugary substance and hop remnants left over<br />

after the brewing — to bring to the NEW Recovery Facility.<br />

“It almost looks like a cream-of-wheat-meets-gelatin (substance)<br />

if I could describe it as anything,” Barth said of the<br />

yeast slurry. “Now instead of sending things down the drain<br />

and having them have to be processed at the wastewater<br />

treatment facility ... we’re bypassing that entire process and<br />

they’re making energy from it.”<br />

About a year and a half ago, Barth said Beaver Island brewed<br />

a batch of beer that just didn’t come out as expected.<br />

“There wasn’t anything technically wrong with it,” Barth<br />

said, but it just didn’t smell and taste exactly like what he<br />

was looking for.<br />

So instead of dumping it down the drain, Beaver Island loaded<br />

up the beer and brought it to the NEW Recovery Facility.<br />

“Pat probably loves when we have a beer go in the wrong<br />

direction, because it generates a lot of energy for them,”<br />

Barth said with a laugh. “But for us, we want to do it as little<br />

as possible.”<br />

It takes about 5.7 million killowatt-hours to power the NEW<br />

Recover Facility each year, according to Assistant Public<br />

Utilities Director Tracy Hodel. In 2018, the facility produced<br />

roughly 85 percent of its energy demand onsite through<br />

solar and methane conversion.<br />

Hodel said 7 percent of that 85 percent of needed energy<br />

that is produced onsite comes from solar arrays at the<br />

facility. The rest (about 80 percent of the plant’s total energy<br />

demand) comes from the methane produced in the facility’s<br />

anaerobic digesters.<br />

“There’s still some (power) that we’re buying,” Hodel said,<br />

but there are plans to add a second generator and have the<br />

facility running completely on energy produced on site by<br />

the end of 2<strong>02</strong>0.<br />

“With adding an additional generator, we will be able to<br />

produce exactly, if not a little bit more, of our total demand.<br />

We’re looking at adding a second generator... and we’re also<br />

looking at adding more solar arrays onsite,” Hodel said.<br />

The second generator could be installed as early as fall of<br />

<strong>2019</strong>, Hodel said, but the facility expects to have it up and<br />

running by spring of 2<strong>02</strong>0.<br />

Mathematical Probability<br />

Source: engineering-humour.com/engineering-jokes.html<br />

Every Friday afternoon, a mathematician goes down to the<br />

bar, sits in the second-to-last seat, turns to the last seat, which<br />

is empty, and asks a girl who isn’t there if he can buy her a<br />

drink.<br />


The bartender, who is used to weird university types, always<br />

shrugs but keeps quiet. But when Valentine’s Day arrives, and<br />

the mathematician makes a particularly heart-wrenching plea<br />

into empty space, curiosity gets the better of the bartender,<br />

and he says, “I apologize for my stupid questions, but surely<br />

you know there is NEVER a woman sitting in that last stool.<br />

Why do you persist in asking out empty space?”<br />

The mathematician replies, “Well, according to quantum<br />

physics, empty space is never truly empty. Virtual particles<br />

come into existence and vanish all the time. You never know<br />

when the proper wave function will collapse and a girl might<br />

suddenly appear there.”<br />

The bartender raises his eyebrows. “Really? Interesting. But<br />

couldn’t you just ask one of the girls who comes here every<br />

Friday if you could buy HER a drink? Never know — she<br />

might say yes.”<br />
