Actually, he was measuring amps. When you measure amps with a fluke meter like that, you must have a load or you will have a short circuit, so there had to be a load. It is reasonable for a turbine of that size to produce 500 watts in 20mph wind.

Make your own alternator. There are instructions all over the Internets.

Hi,
I’m building my own wind turbine and need to know more about what type of alternator to use. Baring in mind that I’m a student and poor, so if possible could you recommend a cheap alternator.
Would a solenoid work to generate a voltage?
Thanks for any tips!

Any chance you can tell me what you used to build it? Me and my mates are going to build one for a school project and we’de like to have a list of materials. £35 looks really cheap

Chances are he is measuring open circuit voltage which means there is no load and essentially no power output. That/s why it is spinning so fast. There is no load. A turbine this size can only produce a few hundred watts in a strong wind.

I would like to see the amps as well. If he is spinning a fixed magnet alternator it’s likely putting out 8 to 10 amps at 500 RPM. The right alternator will put out 5 amps at only 250 RPM. That thing looks like it was doing a 1000 RPM. So not bad.

Looks like the meter is set to DC volts. 21.5 was the highest. It would be interesting to see this experiment duplicated measuring amps. Then we would have a watt calculation, which is the important part. If this rig is producing 21.5volts at only 1amp that wouldn’t even power a light bulb.

are those amps?
January 17th, 2009 at 12:17 pm
alot of power you can save with this amazing thing, hook it up to a inverter and if it has amps, lol, see what happens.

That looks pretty cool! If you’re trying to get an idea of it’s output, maybe you could mount it in the back of a small truck or something on a calm day. You would then know what output was for a given wind speed. Good job!

whoa ****! Don’t let go LOL.

Did he take off?…

good job my freind good job

wHAT GENERATOR IS USED, PS GOOD JOB

kk, sorry i thought it was another joke-vid. i will read more about this stuff because i’m very interested. and sorry my bad english. thank you and have a nice day from CH

The windmill design isn’t optimal. Lay the generator on it’s back, put up some sails and spin it like a roulette wheel. You never have to worry about it facing into the wind because it always is. (When there’s wind).

Hi megavotze, I think you can clearly see that its only a permanent magnet generator with pvc pipes attached to it and when it spins it produces dc current to then charge a battery, may i take this opportunity to invite you to read on the net about home made wind turbines, before you call people idiots, lack of knowledge and research is what makes you make these comments.
Hope this clarifyes it for you then again maybe not.
cheerio

fake – this “thing” must have batteries inside you idiots
February 1st, 2009 at 10:03 pm
your open circuit voltage was 20+ volts max, but what about the short circuit current. As you might know, your max power is the product of the two!!!!!!!

your right my friend but now they have domestic wind turbines that are ring fed into the house maines which require no batteries.
February 6th, 2009 at 10:18 pm
How did you make the alternator? or did you just buy it?
February 8th, 2009 at 5:49 pm
Personally I believe our greatest obstacle is harnessing the energy. As you have shown, it takes a little effort, a bit of knowledge, and even less money to produce quite a bit of energy, but the batteries we use to store it are, among other things, very toxic, inefficient, and bulky. I believe that this is the biggest hurdle before turning wind power into affordable, efficient, eco-friendly transportation, not to mention the biggest thing holding us back from giving big oil the big finger.
