Is this a new windmill concept ? i just drew it up

Your design looks remarkably like a Russian wind turbine design
I saw at the International Inventors Exhibition in Geneva the other month.

There was this Russian inventor, don't recall his name right now,
who presented his (patented!) wind turbine design there.

I believe I included a scan of his info brochure in one of the zipfiles
about the Geneva convention which I uploaded a few weeks ago
(see this thread: http://www.overunity.com/index.php?topic=4430.msg88250#msg88250).

An efficient wind-trap idea.
(for those familiar with Dune )

yes it does have the same concept.  The only thing that was not the same was the open venturi effect on the returning side.  i sent a concept picture to a turbine company in canada,  maybe they will include it in a next design

@ Haliburton.

Hmmm... Very similar concept to those spinning air vents that are sometimes found on top of work vans. Judging by how fast those air vents spin, I think that your concept has good potential.

Only one way to find out... Build it  .
