I'm sure this idea has been mentioned but has anyone any comments ?

That 'windlens' seems to be a lot of material – I wonder at the cost factor. Also, it is nice to see production raised more than twice for a turbine with less than a metre long blades, but how does the increased energy production scale?

Re: People and Klatsch (none / 0)

Sure, you have to wonder about the mechanical practicality of a large scale version and I look forward to seeing that scaled up version tested.

"Fibonacci Tower" (none / 0)

I wonder what the efficiency results would be (ignoring cost), if fixed position smaller windlenses were installed on a tower. I recall about a month ago that a 13 year old demonstrated greater PV efficiency with this concept.

Shrouded turbines of all manner have been studied for decades. They don't scale well, nor do they reproduce lab efficiencies in the field. Yawing a shroud is tough. And the low pressure vortices drift all over the place.

Nice catch Migs, had totally forgotten.
