New Airfoil-Based Wind Turbine

This is a preview of our new turbine. This turbine is still under development but is performing very well in initial tests.

This turbine is much lighter and faster than previous turbines I've built. For one, it is a lift based turbine utilizing symmetrical airfoils rather than a drag based turbine such as the Savonius. This has both advantages and disadvantages. This turbine really goes, but the Savonius starts up easier in super light winds.

I would like to thank the following companies who produced custom products or provided services which were integrated into this turbine prototype.

Liberty Machine and Tool -


FC Sails -

Thermal Foams, Inc. = -

Here is a YouTube video of this prototype turbine.

Hello you have email??
i want to purchase some of the blue drum wind units..How much would you charge to make 3 to 5 of them ..

please contact me at

jeff i own land on a remote island (middle caicos in the turks and caicos) islands and would like to talk to you about maybe coming down for some fun and sun and some work helping us with power ==== this winter ----- when it's cold there ---- anyway if you'd like to connect -

Hi Jeff,

Thank you for sharing your wind turbine projects. I've attempted one using a couple of bicycle wheels joined with a three-foot axle and airfoil-shaped vanes which looks somewhat like your Gyro Mill (not as elegant, though). I've connected it to an alternator with a bicyle chain, and it turns pretty well in a stiff breeze. No voltage, though, when I hook the alternator up to a battery--I'm told the alternator requires a high RPM to generate electricity, but judging from the geared generator design you built, you were able to get 13 - 14 volts without super high RPM. Any thoughts would be appreciated.

Best regards,

Bob (

dear mister Berezin .
can you help me to find a system capable to take all the mesures from my vawt test turbine at a PC
the mesure that I need is 1° the volt
2° the ampere
3° the watt
4° the wind velocity
5° the rpm from vawt,149.html.
here you can see my test turbine
my mai adresse
my dream is find a system capable to take all the mesures from the test turbine at a PC.
it can make my work more easy ,now I take all the test with a camera and than I see slowly and put the mesures at a paper ,it's very long.
excuse my english he is limited
thank you
