The alternator requires two rotors to be built. The first step is to build a wooden mold. Each rotor will be made from 12" diameter steel disks each with 12 magnets on it. Once we've built the rotors we'll cast polyester resin around them to keep the magnets in place and prevent corrosion. In order to make a neat casting we need to build a mold out of plywood. Like many other things in these plans, there are alternative ways of doing things. Here we'll detail exactly what we've done. Some of the pictures show two molds in use, but you only need one. See the picture above for dimensions of all the parts

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
