A windmill is a device used to convert wind power to workable power through the use of a rotational motion and adjustable vanes or sails. Windmills were initially used for crushing grain but as persons have altered to being more involved with conserving the environment and discovering reservoirs of natural energy, windmills have increased in popularity.

Instructions
As with many other things you can purchase windmill plans or kits to lessen your work. The plans will give you detailed procedures for assembling a windmill and will also have a comprehensive menu of essential materials to assemble a windmill. A windmill kit will consist of plans as well as all the materials you need to construct the windmill so you will require nothing but a few tools. If however, you opt to build a windmill with no added assistance then here is what you have to do.
Let's begin with the generator; some people choose to make their own generator however, an easier alternative is to buy a permanent magnet DC motor. You want a motor that will produce good current at a low rpm level; a 30 volt motor rated at 325 rpm ought to create around 12 volts thus a motor such as this would be ideal.
For sails/blades you may purchase pre-made blades or make blades out of wood, aluminum or PVC pipe. To see exactly how you need to cut the PVC pipes visit one of the websites online like yourgreendream.com which will give you detailed instructions on what to do. Once you have cut out your blades using a saw, use the sander to smooth the edges of the blades to make them even more efficient.
You will require a hub to bolt the blades to and to secure the motor to, basically any flat disk about 5 inches in diameter will do. Drill 2 holes, one below the other into the blades and drill matching holes through the hub, next use the nuts and bolts to secure the sails to the hub.
The windmill section is now complete however, you need a mount to fix it to. Strap the motor to one end of the piece of 2x4 board and use a piece of PVC pipe to shelter the motor so it is protected from rain. Lastly secure the heavy sheet aluminum to the opposite end of the 2x4 board to act as a tail for the windmill.
For a tower use a PVC or aluminum pipe; bury it in the ground and concrete it into place, use sandbags to furthermore secure the tower in place and then mount the windmill on the tower.
Purchase a wind power control system for transferring energy from the windmill to the batteries, from any Alternative Energy store. You need electrical cables to connect the windmill to the power control; run the cables from the windmill down through the tower and join it to the power controller. Now it's time to test out your windmill.
Tip
Remember that the taller a windmill is the more wind it will reach. Therefore you want your windmill to be higher than any potential hindrance.
