Here at EcoRenovator, we definitely think that DIY is where it’s at. So it goes without saying that we jumped when we say this very cool DIY vertical axis wind power generator by Faroun. The total cost of the project is between $125 and $375, depending on what generator you use, with the more expensive WindBlue Alternator starting at around $250 itself. The issue with cheaper alternators is that it takes higher RPMs to get up to the desired voltage, which means your generator will be cheaper, but will also produce less power.
As you can see in the picture, this verticle axis turbine is very compact. Unlike many traditional wind power set ups, it doesn’t need to be unreasonably high or occupy a large footprint. However, it does need to be windy enough to actually spin the thing!
This turbine is made by cutting apart PVC pipes so that the halves are mounted onto 12″ bicycle wheels from old kids’ bikes.
Then the whole thing is mounted in a box and propped up somewhere where it won’t fly around, hooked to the alternator, and let go. The designer wanted to get 100 watts out of the setup, but has since realized that it will only spin at up to 550 rpm so the current, cheap alternator is not going to work out. Definitely a good reason not to skimp out on certain parts.
Nonetheless, a very interesting and innovative idea. I hope he can get a new alternator so we can see how much power it really puts out.
