Unique Savonius wind turbine

tractorgp · May 15, 2015

Been making some progress on the horizontally oriented Savonius wind turbine. Took this short video today with my tower mounted security camera. I'll post more info as the project progresses. The idea is to see how an "augmenter/overspeed" feature will work.

That is a project I will be watching.

Are you going to make your own direct drive pm alternator?

That is my thought and the design allows for it but this is mainly a test of the augmenter/overspeed control ideas. The turbine is in the "drag" category of turbines so not that efficient but the augmenter feature will (I hope) improve the efficiency somewhat - but I won't have any real way of proving that. This is a fun experiment and in terms of wind turbines it will not be that practical compared to alternative designs.

Here is a link to a wayback machine archive of one that was supposed to produce 250 watts. He never produced the kit after his lawyers advised him not to.

This is THE way to harness wind energy. Those propeller toys are junk compared to this. This belongs in the wind turbine thread.

Thanks for the link - will check it out. Don't know why lawyers would advise him not to produce a kit or whatever as the Savonius patents would have run out decades ago.

If you mean the thread started by buickanddeere http://www.tractorbynet.com/forums/rural-living/336165-wind-turbine-just-opened-mail.html I wouldn't take a chance. I'd crucified in a blink

I wasn't brave enough either....

He said his lawyer advised about the potential for excessive voltage production. For that you would need high winds, open circuit voltage, be standing in bare feet, in the rain, in the mud... and touch it with your tongue.
