Electricity is flow of electrons (Negative Charge) from one body to another. In order to understand this is some detail, it is important to understand thestructure of an atom. An atom consists of three elements –electrons, protons and neutrons. Electrons are negatively charged (–) particles,...
1: Wind Power to Electricity You might have seen giant wind turbines spinning on hilltops. Well, with this experiment, you can make your own model turbine to try generating electricity from wind. Start with a 1.5 volt direct current motor. These battery-powered motors are available from hobb...
In Michael Faraday's generator, coils of copper wire rotating between the poles of a magnet produce a steady current of electricity. One way to rotate the disk is to crank it by hand, but this isn't a practical way to make electricity. Another option is to attach the shaft of the gene...
make sure that the lights and the electric fans are turned off when there is no one in the room. Set the room temperature at above 26℃. Remember to turn off the computer when you are not using it. Secondly, try to form the habit of turning off the tap after it is used. Use...
So, electricity needs a conductor in order to move. There also has to be something to make the electricity flow from one point to another through the conductor. One way to get electricity flowing is to use a generator. Holy Electricity In the late 19th century, electricity truly had a nobl...

(tires,transmissions, et cetera), we'll ignore that part of the car and compare efficiencies up to the point where mechanical power is generated. Let's start with the fuel cell car. (All of these efficiencies are approximations, but they should be close enough to make a rough comparison....
