DIY Wind Turbine for $32

8/28/26:

Your automobile's 12 volt charging system will put out a surprising (at least to me) amount of power. At idle, my van uses about 3/5ths of a gallon per hour.

It wouldn't be cheap nor efficient, but why buy anything? Keep the energy requirments low, and just hook up your 12 volt system in your car to your off-grid battery, and let the car's alternator charge her up.

I've already tried it out on the ranch, so it works. But of course it does, otherwise, how could you drive your car?

It may be a bit better to upgrade the voltage to 24 volts. I've tried that too in my experiments. There's a 24 volt inverter just collecting dust.

That reminds me, I haven't worked on my solar power trailer for awhile. Something wrong with the wiring. Always is. Anyway, you don't have to complicate things too much to have a workable scenario. Remember the KISS method--Keep it Simple, Stupid.



4/3/19: The original post follows below:





Retired at 40


He says that it works, but offered no proof.  It may have a weakness that even I can see.  Nevertheless, I am putting it up because it might actually be worth an attempt.  Someday, maybe.






A test of an actual out - of - the - box system rated at 400 W, but actually it got only about half that, he says.





Why bother with this???  Maybe for the exercise???

It generates about 10 amps according to his test.  A couple of solar panels will do that much, and would cost less.

Wind could be used if you want something of a backup in cloudy weather, which also has wind.

Also wind is 24/7, while the sun is only half a day.

Here's another dude, John Daniel, who has a video showing his set up.  He is enthusiastic about his stuff, so maybe this would be worth another look some fine day.









Here's an older video below, which is probably the same turbine a year later above ^^^^^^

Update:

Installation of the wind turbine:

Shows how to do some welding.  Interesting.
