OOPS 14<br />

To appreciate <strong>the</strong> full glory <strong>of</strong> Edison’s go<strong>of</strong>, it helps to understand<br />

<strong>the</strong> times and <strong>the</strong> extraordinary stakes for which <strong>the</strong> nation’s most prolifi c<br />

inventor was gambling. In <strong>the</strong> late 1880s, <strong>the</strong> world was at a crossroads.<br />

Electricity had been discovered and harnessed, and clearly had <strong>the</strong> potential<br />

to change <strong>the</strong> world, but <strong>the</strong> era’s leading technologists hadn’t yet fi gured<br />

out <strong>the</strong> best way to generate and distribute it on a large scale.<br />

It also helps to understand <strong>the</strong> two different types <strong>of</strong> electricity.<br />

Any electrical device requires <strong>the</strong> movement—a “current”—<strong>of</strong> electrons<br />

for power. At <strong>the</strong> time Edison created <strong>the</strong> first commercially practical incandescent<br />

lightbulb in 1879, all <strong>of</strong> <strong>the</strong> electricity used in <strong>the</strong> United States<br />

was direct current, or DC. With direct current, electrons fl ow constantly<br />

along a wire like water through a hose, with users siphoning <strong>of</strong>f power<br />

along <strong>the</strong> way. That type <strong>of</strong> low-voltage electricity is reliable and safe, but<br />

not very efficient because it requires a generating station every half mile<br />

or so to refill <strong>the</strong> “hose.” Edison, holder <strong>of</strong> a record 1,093 U.S. patents,<br />

was a DC man because he had invested heavily to develop systems and<br />

equipment that relied on direct current, and he intended to make a lot <strong>of</strong><br />

money electrifying <strong>the</strong> world with his DC-powered inventions.<br />

There was just one problem: Edison was wrong. An eccentric Eastern<br />

European immigrant named Nikola Tesla, along with visionary Pittsburgh<br />

industrialist George Westing house and o<strong>the</strong>rs, was pursuing a<br />

different course, developing motors and related systems that ran on alternating<br />

current. AC electricity keeps electrons moving (and producing<br />

power) by quickly cycling <strong>the</strong>m back and forth along a wire between positive<br />

and negative charges. It can be distributed at much higher voltages,<br />

making it more powerful and efficient than direct current, and it’s far<br />

easier to deliver across large geographic areas. Also, if properly handled,<br />

AC electricity is perfectly safe. Although <strong>the</strong> Edison Electric Light Company’s<br />

1887 annual report dismissed rival AC as “having no merit [and]<br />

notoriously destructive <strong>of</strong> life and property,” it didn’t take long for most<br />

reasonable people, including some <strong>of</strong> Edison’s own engineers, to realize<br />

that <strong>the</strong> future belonged to AC.
