Otherpower.com’s large homebrew wind turbine on a breezy day
year with just the wind turbine and often times it's more power than we can use). The system charges a 48V battery bank which we feed an inverter with. The inverter converts the 48VDC from the batteries into 120VAC to run our shop and home.

This turbine is the real thing, and has NOTHING to do with GreenEnergyToday or Earth4Energy.
Earth4Energy is a scam! For 50 bucks they tell you to buy a little surplus tape drive motor, stick an 8 foot diameter PVC pipe rotor on it, and have a dangerous machine that will blow into tiny pieces during the first high winds. It doesn’t even furl to protect itself, like this one does.
Shame on you GreenEnergyToday — you are a scammer. Learn how to build a real wind turbine instead,
GreenEnergyToday: We did not follow your advice. Our design is our own, and very much inspired by Hugh Piggott. I see you promote earth4energy, which is not in any way similar to what we do here. In my opinion, earth4energy is a scam, misleading, lacking necessary information, telling folks what they want to hear and not reality. Its an expensive ebook with very little content! What we do here actually works ~ it’s not however easy, or cheap.
I’m impressed and i’m glad that you followed my advice. Anyone who’s interested in building a wind turbine can contact me for help.
I might not be able to answer you straight away since i’m busy. But anyone who asks will get an answer.
The machine has been up/running now for about 2 and a half years.
Nice work. Not many can home built them to last, or I should say, many have built them that did not last. How long has it been running for you now?
have you ever tried to use a centrifical clutch on any of your designs? to change gear ratio during high wind or would that cause too much drag?
Good stuff.
Chances are it would be cheaper to buy a car inverter.
it allows the tail to stay with the wind, while the thrust against the alternator, once it overcomes teh weight of the tail, pushes the alternator sideways, reducing the blades exposure to the wind. It is a sort of very simple, automatic ‘furling’ system so that the wind turbine can reach full output at about 25 mph but not have to suffer through the extremes of higher winds. Power in the wind is related to the cube of wind speed, any sane wind turbine design needs some system to save itself.
No. Mine is an older Trace SW4048. I think one would be hard pressed to build their own inverter for anywhere near the cost of a new one. New inverters these days (even my older one) are quite powerful, good wave form and very clever about managing the whole power system.
what is the purpose of the rotating tail of the wind turbine? I’m not sure i understand why it is there.
did you make your own inverter?
That is Dan B’s wind turbine. Those folks in know how to get their own free electric energy.
Check out their site.. lots of information.
Cheers!
…Baby steps… but at least it’s a start.
Our system runs at 48V. The machine is setup to furl at about 3KW (60 amps or so) although I do sometimes see peaks of twice that. I could do things to get more impressive performance in high winds but there’s little point in a battery charging system – if its windy, I have more power than I can use. I’m more concerned with good efficiency in low to average winds. (most of my energy is from 10ish mph winds). There is a page about the project at: otherpower(dot)com/20page1.html
How much current are you getting and volts? Thanks for any replay.
AWESOME, WE WANT ONE! TIME IS COMIN
Nice Job.

Awesome!
