Homemade Wind Generator

 DIY Wind Generator

Are you headed for the beach or going camping in the mountains? Maybe you live on a boat, visit a remote cabin or you're living off-grid. Electricity is yours for the taking as long as the wind is blowing... And you can get it on the CHEAP with an easy homemade wind generator. Light up that storeroom, barn or use the generator to keep all your vehicle batteries charged too.

My off-grid cabin's electricity comes from solar and wind power, stored in 6-Volt golf cart batteries. A charge controller and battery minder keeps my system from under-and over charging. The whole shebang cost me less than $1000 and I have lights, fans, TV and stereo, refrigeration, and a disco ball that goes up for special occasions.

If you can turn a wrench and operate an electric drill, you can build this simple generator in two days: one day of chasing down parts and one day assembling the components. The FOUR basic components include a GM pickup truck alternator ($40 new), a GM fan-clutch assembly ($35 used), the bracket for mounting the generator on a tower or pole ($25 galvanized pipe and fittings version), and a tower or pole ($20 for 15 feet of 2" tubing, used). If you're a Ford guy or a MOPAR gal that's fine, just make sure the alternator has a built-in voltage regulator. You'll also need some electric cable or wires to hook it up to your storage battery. I used 8 gauge, three-strand copper wire pilfered from the oil patch. (And they said the transition from fossil fuels to renewables would take years. Pfft!)

My Wind Generator Parts List

Car/Truck Alternator - GM 1988, 350 motor, alternator with built-in regulator (used in illustration). Almost any alternator with a regulator will work but use a new one. It should have a warranty.

OK, This system could work....if you had 50 MPH winds... An alternator,(automotive), requires a minimum of 700 rpm to activate the field coil for electrical production, Running the blade directly off of the shaft is extremely unlikely to achieve this speed under less than hurricane conditions. This problem can be overcome by inserting permanent magnets in the spaces left open on the armature. Doing this will allow the alternator to produce electricity without having to activate the coils.

What is so incredible about it? in the first place the fan is wrong way around, there are no wires connected to it, it look like a redneck rig that did not work so they gave up. It can work with some modifications and some electronic circuitry to cut the field current when there is no wind, or the rotor have to be fitted with permanent magnets in the place of the rotor coil. Some more improvements will be to change the stater coils from star to delta.
