Build Your Own Homemade Wind Generator Using Wind Energy To Create Free Electricity.
Homemade Wind Generator — RD Copeland @ motherearthnews.com
Building your own home wind generator is simple, if you are equipped with good plans and knowing what you need to act upon. If you’re around a reasonable amount of wind, pay out a little cash and one or two weekends and see what you can get out of it.
To completely understand the idea of the wind generator, you must understand how electricity works. Try this DIY project and you will considerably reduce your utility bills, and protect the environment. Many thanks to author ‘RD Copeland’.
Homemade Wind Generator. It’s all about energy, from renewable sources to energy-efficient usage.
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…
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.
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. Bracket Assembly for Mounting Alternator/Fan
If you have a welder, making a bracket is simple. I used 1″ square tubing for all the bracket pieces and a 2-feet long piece of 1″ pipe for the Rotating Stem that fits inside the pole. If you don’t have a welder, fear not. The Bracket Assembly can be fitted up with 1/2″ galvanized pipe and fittings.
Here’s a list of the pipe fittings you’ll need:
1/2″ Tee (5X)
1/2″ Elbow (2X)
1/2″ X 12″ Nipple (2X)
1/2″ X 6″ Nipple (2X)
1/2″ X 1-1/2″ Nipple (2X)
1/2″ X 2″ Nipple (2X)
1/2″ X Close (2X)
A tail fan to spin the generator around lining it up with the wind’s direction must be attached to the 12″ nipple at the back of the bracket. Cut a fan out of old tin siding or roofing with tin snips or a cutting torch. A right angle triangle shape works best.

I see this posted often and it’s bogus! The power output will barely power a few low wattage lights. The blades are not made for producing torque and an alternator would be my last choice of gererator. You can make one that works good using a step motor from a washing machine and cutting the wing shaped blades from 6″ PVC pipe.
Hi, do you have specific instructions for your design?
I was about to post the same thing….this guy is a back woods hick that refuses to stay in his trailer.
Except in very high winds how could this possibly generate any power?
Billy William Osborn
I think I’ll make this
It would ttake at least 4 hp to make it work , I call this crap
Nice
Danny Lopz Pablo Moreno Gerardo Puente Jr. Ricardo Castro gotta try this
dont work, what excites the alternator? it can be done, but its not gonna make decent 110 power. i agree with howard daye
It doesn’t have to make 110 it only needs to make 12V to charge a battery
Great redneck, yard art. Back in the 50s my Dad charged car batteries using a car generator attached to an electric motor. Important safety tip: Do so in a well ventilated area and keep your fingers away from the fan belt.
This is and has been proven to be a waist of time. You want to make a wind charger, get an old tread-mill someone has thrown out and use the (approx) 90vdc permanent magnet motor. You need to study up on wind charger circuits etc…
That is what I was going to bring up also Howard. It would take at least 4′ to 6′ blades and a stiff breeze.
Wouldn’t work, it would have to spin at about 2000 rpm to generate anything.
You’re kidding, right? Even more useless with that clutch fan.
Oh wait, can’t do that. Heat from the alternator turning creates heat and will add to Global Warming. lol
I tried to build a battery charger with a altinator and a 2.5 HP gas motor, under load it would stall. no way wind would drive this.
It generates ‘wind’, with an alternator?
And maybe power your yard light.. What excites the generator?
What do u use as a slip ring

Great idea,it works got 12v and 110,gotta have insight it will work.
