How to build a wind generator
« on: February 18, 2009, 11:14:22 AM »
OK, didn't see much in the area of how to build a wind generator in your garage on the blog so thought I would put out some info I have found.  I will include the video and the source from which he gets his parts.

Those look like standard car alternators on that website.  Can these be used to charge batteries?  It works in my truck, why not in my shed?

Wind turbines are usually (?) used to charge your battery bank.  There isn't usually a steady wind to supply the power to whatever you need it for.  There are some plans floating around that use a standard alternator. 

I've been digging into micro wind power for a while.  There's some good info out there.  Here's a page on building a savonius rotor to power a driveway gate. 

Here's another page on using an alternator to charge batteries.  Not a wind powered page, but still useful information.

Car alternators are a bad idea for a wind turbine.  They don't achieve the a usable voltage until they are at a high RPM.  Your truck motor can spin that thing far faster than the wind ever will.

I'm in the beginning stages of gathering parts to build a wind turbine.  In all my reading I like the ideas at thebackshed.com.  Another really good site is http://www.yourgreendream.com/.  They talk about Fisher & Paykel washing machine motors and they really sound like the ideal wind turbine motors.  As the US doesn't get a lot of these it has been found that similar (if not better) motors can be found on the Whirlpool Cabrio top-load washers and newer LG front-load washers.

I also like the plans I've seen on making a simple set of blades out of 8" sch80 PVC pipe.  Looks simple and while it may not be as efficient as engineer designed, store bought blades, you could afford to build two windmills with these for the price of one set of the perfect blades and be well ahead of the game.
