A Van de Graaff generator operates by transferring electric charge from a moving belt to a terminal, usually, a hollow metal ball. It is an electrostatic generator, similar in principle to what happens when you rub your feet against a carpet and touch your cat!
There are a few websites that can show you how to build eco power generator like: loveforlife.com.au/.../10/.../free-eco-power-free-eco-power-generator... or www.teslahojomotor.com/free-of-charge-eco-power-electric-generat.
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
Most sold in the U.S. are made at Honda's Swepsonville, North Carolina, Power Equipment Plant. As Honda builds small engines all over the world you will have to look at the data plate to see exactly where it is made. Even though Honda does build engines in China don't be fooled by a Chinese clone made in China. It will not say Honda on it but it will look exactly like a real Honda engine.
AA batteries i would say ;)
The build up of a charge on an object can be referred to as a static build up charge.
You should honestly be able to build a wind powered generator in any town because its the one type of generator that causes the least environmental damages. You can ask for a permit from your city hall.
A hydroelectric generator does not require much maintenance. If you build it right or if you purchase a decent generator, you should not have much problems.
Yes
not without a permit
List the factors that affect the voltage building in D.C generator.
The presence of moisture in the air increases the conductivity of the air. This can create a path for the electric charge to escape the van de Graaff generator before it can build up, making it less effective in wet weather.
