Finally you can rest your green conscience by building your own wind powered generator. This DIY wind turbine   is easy to build especially since the authors show you how with step-by-step instructions. The wind turbine is unsophisticated in design but efficient as it produces about 84 Watts with 30mph winds. It won’t eliminate your entire electricity bill, but it’ll help you start your journey into the alternative energy movement.  Check out our   DIY Free Energy tutorials and more details below. Most of the parts needed to assemble the make-at-home wind turbine can be salvaged making the total build pretty cheap. The author’s website at  Velacreations.com  guides you through the nitty-gritty of putting the contraption together.  So go ahead, give this windmill a whirl. Reduce your electric bill and your carbon footprint in one go. Parts font size       Print   Email Tagged under   energy ...

updated 22-02-10 This was a very successful project, I used an off the shelf  3 bladed propeller, beautifully balanced and extremely strong, made from glass filled nylon, they are designed as 'pusher' props and can spin at up to an amazing 13 000 rpm when driven by a radio control plane engine. I suspect just 2000 rpm will be my max as a wind generator. I am using this propeller mounted backwards, so the flat side is facing forwards and the true aerofoil is on the back. Having the blades pre made allowed me to focus my attention on matching the alternator to the blades characteristics, having seen Ed Lenz's work over on  Windstuff now  using radial air core alternators, I decided to work along similar lines. The benefit being, no iron in the design therefore no  cogging   effect that would kill a tiny wind turbine (mechanical resistance making it barely start up). I sourced a very powerful N42 Neodymium cylinder magnet  here  that differs...
