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. The airfoils were designed using open source design software and fabricated with composite materials for light weight. This wind turbine also uses sealed bearings and requires no oiling or regular maintenance.

Hi, I am trying a version without the circles now. I wanted to get the wings out further to see if the leverage increased the speed. I should have it done in a week or so.
nice work. i’ve …
nice work. i’ve made a few turbines like this, and in my experience, the circles you have at the top and bottom were tremendous leeches of power and rpm. have you tried building this design without some of that excess material? i would make 3 arms that are only as wide as necessary. just a thought. happy tinkering!

It has magnets on the bottom and a stationary coil beneath the magnets. I need to raise the coil now because it is too far away from the magnets and then hopefully we will get some juice from this. In less than a week I hope to post another video showing the electrical generation for this vawt.

whew…check out the rotation on that.. im impressed… one question…when you put a alternator attachment to it, doesnt it need to be geared??? maybe i missed something
