Practical Guige to Free Energy Devices

These metres show more than 100-watts being generated. However, production cost is always a major
factor in these things, especially since the people who need them most are the people with least money.
Perhaps a version which is driven by an existing bicycle might ease the situation – that method is already
used for some exercise equipment. Another factor which might be missed by designers is the fact that the
people needing this equipment are labourers and will be tired after a long, physical working day. Of course,
the pedalling would be less effort for them due to their much higher muscle strength. The addition of two
small motors like Chas Campbell does, would probably make the design self-powered and do away with
most of the construction – pedals, belts, seat, etc.
In August 2016, Manoj found that his plans for shipping completed bicycles into India from his newly-built
factory in Singapore, was effectively blocked off by import restrictions. So, He is building a factory in India
and he expects production there to be implemented in 2017. He also found that a number of changes
needed to be made because it is primarily women who are free to do the pedalling. The changes include a
reduction in size to allow for smaller people, a chain guard to protect long clothing, a battery ,low-voltage
setting of 11.5 volts, a reduced gearing to allow easier pedalling, and finally, a detachable battery so that the
power can be mobile. The main application is lighting, although I suspect that the lighting efficiency is not as
high as the 1000-lux for just 1.5 watts of the LED designs shown in the previous section of this chapter.
Low-cost Cooling Systems
When most people think of air-conditioning systems they think of large pieces of equipment which are
expensive to buy and expensive to run and which are mounted in one fixed location. While those systems
are certainly effective (although, often noisy in operation), there are other ways of improving living, travelling
and working conditions. Ways which are not very expensive to buy and which are not expensive to run.
Many people have made effective air coolers and shared their designs using web videos, and I should like to
thank them for showing what they have achieved.
Simple cooling systems can use two different methods of operation. One method is to use ice which has
been produced using an ordinary refrigerator or freezer (those being very common in places where aircooling
would be considered an asset). Another method uses the well-known principle that when water
evaporates, it draws heat from its surroundings as part of the process.
The general idea is to cool some air and then use a fan to blow that cooler air to where it is most effective for
the user. Typically, cooling is most needed inside buildings and inside vehicles. Inside buildings, mains
electricity is often available. Inside vehicles, twelve-volt or similar levels of DC power are generally available.
In both locations, a solar panel (possibly aided by a car battery for night time operation) can operate a useful
system.
What we are talking about here, is a small system which will not be as effective as a large commercial unit,
but yet is something which can make a great improvement in a small area. Something which does not seem
to occur to many people is that you can have more than one of these units operating in a room or vehicle.
While I am delighted that people have shared their simple designs on the web, they usually assume that the
components which they have used are available to everybody, and that is very much not the case as the
items which are readily available locally vary enormously at different places around the world. For that
reason, I should like to discuss the basic principles used so that when any chosen design uses something
which is just not available locally, you can choose a suitable alternative which is readily available locally at
low cost.
Let us start with indoor cooling. The unwanted heating comes mainly from the sun shining in through
windows, and from heat leaking in through the walls because the outside of the walls is being heated by
sunlight falling directly on it or by hot air flowing along the outer surface of the wall. Of these two main
sources of indoor heating, the sun coming through the windows is generally the greater source of heat.
If a room has one or more windows facing the sun and one or more windows which do not face the sun, then
a first step might be to use shiny silver-faced insulation cut to exactly fit the windows through which the sun
shines. Curtains can generally hold the insulation in place on their own, but if that is not convenient, then a
few small pieces of adhesive tape work adequately and can be used again day after day. The outer shiny
layer reflects most of the sunlight back out of the room. The outer surface of the insulation sheet heats up as
not all of the light is reflected, but the insulation layer stops most of that heat actually entering the room,
resulting in a major improvement in the room temperature, although the light level is reduced considerably as
