half wind speed doesnt provide half the power, maybe a small water fall could easyly provide half kilowatt.
Nice project, congrats

hi there guys, oops i did it again and changed the design of the vanes/blades by building V8-4″.
it is at http://www.instructables.com under faroun Vawt v8-4″.

now i think it is time to show the output.

later

This is pretty cool. It would be interesting to see if any kind of airfoil can be made from PVC or a similar material; then a Darrieus design could be made. Savonius rotors are designed to primarily use only drag forces, so they can only spin as fast as the wind is blowing. Darrieus rotors primarily use lift forces, like HAWTs, and can spin much faster than the wind speed. So, yeah, just some food for thought!

He states 100 watts at 35 kilometers per hour. Which is equivalent to 21.75 mph.

So… 50 watts at about 10 mph isn’t too shabby.

I like the idea of people looking into decentralized power. There is a theory I came across in science fiction that attributes the down fall of civilization to centralization. If we all count on one thing, say a power grid, what happens when that one thing goes down? Chaos?

A geared alternator from a junkyard would probably be much more efficient. The use of pvc pipes is interesting, I’d like to experiment with bigger ones.

100 watts at 35km/h (21mph) is not very efficient power production. It is hard to find average wind speeds over 14mph. At 14mph this “100″ watt machine would only produce 34.3 watts. And 14mph is a hard wind site to find at ground level. 5mph winds would result in a mere 1.3 watts of power. This machine would take forever to simply payback the amount of energy it took to build.

but cheers to trying.

This is great, I agree, keep these kinds of articles coming !

Those ametek motors are great for beginners wind projects. (Not that this is a beginner project)

I did a small solar power install, blogged about it in the url when you click my name ..

Thanks Hackaday !

100 watts that’s pretty ambitious is it not?

I’d like to see a vertical wind turbine made from coroplast panels

i agree… any solar or wind power or greenhouse hacks would be welcome. (i’m getting ready to build my first greenhouse, kinda like hacking the weather!)

im glad i get to be the first to comment i love the site.this is pretty cool try and get more post like this thanks for the hard work guys
