I can't help but wonder if the new spiral shaped wind turbines recently
brought to our attention like the ones RC Macaulay showed us at:

I wouldn't know . . . but from what I have seen many serious accidents are
caused by towers collapsing and by electric fires. Both would happen with
the spiral turbines. I suppose the only common accident that would not
occur would be falling turbine blades.
The design looks like a turbine called the Darhelius. I'm sure that
the machine is more stable, but as I understand it, the design is not
particularly efficient as an energy collecting source. The amount of
area presented to the wind is rather small, compared with a standard
prop design.
