When you know how to build a generator, you will be able to supply yourself with some free electricity. You can build a small, experimental generator and, when successful, you can move on to making bigger generators, which will be able to provide more electricity and power more devices.
Different kinds of generators use various sources of energy such as solar, wind, magnet, and others. Basically, one form of energy is harnessed and converted to another form of energy which is electricity. You will need some items, which you can get from a hardware store.
Just keep in the mind that the bigger the wire length, the more electricity will be produced. A powerful magnet will produce more electricity than a low powered magnet. In this kind of generator, mechanical energy is converted to electricity.
Assemble all the items together before starting, so you can finish the work at one go.
When you want to build a bigger generator, you have to use the same principle. But you have to use a stand and a shaft to move either the copper reel or the magnet to generate electricity. You can build a shaft which can be hand cranked (like an old-fashioned sewing machine) to make a hand-cranked generator.
By using two reels instead of one, parallel to each other and mounting them, you will be able to generate more power. Remember that this generates AC power, which can power very few devices as many gadgets work on DC current.
Larger and commercially used generators use a motor, which is usually fuelled by diesel or gasoline. These are not environmentally friendly as they emit noxious fumes and pollute the atmosphere. Other generators may work on electricity or even steam. All generators use magnets, copper wire, and movement to generate electricity.
Sometimes a simple generator can use a stationary cycle’s pedal power to work. You have to be careful that no wires come in the way of the movement. The generator connects to the wheels’ axles and the movement helps to generate electricity. Once again, this has limitations, as you won’t produce a great deal of electricity by this method. How to build a generator can be an easy home project.
