Plan for Progress  

A windmill is a device utilized to change wind power to useful energy through the employing of a rotational movement and adjustable vanes or sails. Windmills were initially utilized for grinding grain however, as persons have become more interested with preserving the environs and discovering reservoirs of environmentally friendly power, windmills have been enhanced in fame.

You probably think assembling a windmill of your own is too expensive but you have nothing to worry about since you can build a windmill yourself for about $200 and the long term savings a windmill will give you will be well worth it. So if you are interested in building a windmill of your own here are a few tips for building a windmill approximately 5 feet tall.

Instructions

As with a great deal of other things you can purchase windmill guides or kits to reduce your work. The blueprints will give you detailed procedures for constructing a windmill and will also have a exhaustive menu of essential items to build a windmill. A windmill kit will consist of plans as well as all the materials you require to build the windmill so you will need nothing but a couple tools. If however, you choose to make a windmill with no additional aid then here is what you have to do.

Let’s begin with the generator; some persons opt to make their own generator however, an easier option is to purchase a permanent magnet DC motor. You need a motor which will turn out good current at a low rpm level; a 30 volt motor rated at 325 rpm should turn out about 12 volts therefore a motor such as this would be ideal.

For sails/blades you can buy pre-made blades or make blades out of wood, aluminum or PVC pipe. To see just how you need to cut the PVC pipes visit one of the websites on the internet like yourgreendream.com which will provide you precise guidelines 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 need a hub to bolt the blades to and to secure the motor to, just about any flat disk about 5 inches in diameter will do. Drill 2 holes, one below the other into the blades and drill matching holes into the hub, then use the nuts and bolts to fasten the sails to the hub.

The windmill piece is now done however, you need a mount to attach it to. Strap the motor to one end of the piece of 2×4 board and use a piece of PVC pipe to shield the motor so it is shielded from rain. Lastly fix the heavy sheet aluminum to the opposite end of the 2×4 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 position, use sandbags to additionally fix 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 join 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 try out your windmill.

Tip

Bear in mind that the taller a windmill is the more wind it will catch. So you want your windmill to be higher than any potential obstacle.
