Not to sounds grouchy...
but it seems like every VAWT page I see (especially for those machines which are under development) starts out with a long list of all the "advantages" of that particular machine. At least this page doesnt list all the drawbacks (noise, reliability issues, killing birds etc etc... ) associated with proven workable designs.
But this machine is talking 1KW @ 400 rpm. To actually get 1KW from such a machine, I think it would have to be HUGE (I could be wrong..) - and at that size, I'm very doubtful it would spin anywhere near the 400 rpm that the AWP 3.6 needs to see.
It's neat looking, and interesting though... I think at some point after seeing so many "under development" VAWT wind turbine pages out there - most of them completely unrealistic... I have become skeptical.
Interesting page though and thankyou for pointing it out!
