If you want to be green, just grow some vegies in your garden and then spend the money you save on planting trees or buying CO2 offsets.

in this case you should get some of your community to help building turbines, so people know what it is all about, may be they'll say yes afterwards... i live in switzerland, means i could just build some of those, put em up and whait for people to come look at it and ask questions about it

Sealed and lithium-greased bearings are more efficient. Excellent idea using those drums.

Research at Sandia Laboratories suggests an overlap of 10 to 15% of the bucket diameter, not 50%. I suspect you're loosing a fair amount of power.
You ought to hookup a simple home-made salt-water dummy load and check the power. Piece of cake.

The problem with doing that is that it would have to require a huge tail to align it with the wind. If you're going with such a system you might as well construct a hawt instead of vawt as you get more power out of a hawt.

Interesting take. Personally, I think it is awesome, but even if I did get it built and implemented (without my wifes approval) my community platt would probably say NO because it is very non standard. In Oklahoma (where the wind comes sweeping down the plains) it would be a great place to have a couple of these bad boys. In fact I would be worried that they would get worn or broken from over use.

lol, the big NO is one more resason to do so:-) if possible in the frontyard so that everyone asks: "dood, whats this gonna be??"

greasing the bearings or spraying wd/40 will help lower the resistance. the weight of the barrels probly help keep it spinning aswell. great vid!!

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!

I love the low cost concept and I am very impressed. At the same time the smurf blue would get a big NO from my wife (hehehe). I'm glad that you posted this video, it lets me see the possibilities of engineering with limited parts, materials, and capital. Great job. |
