VERTICAL AXIS WIND TURBINE WINDMILL ALTERNATIVE GREEN POWER

Excellent. The video mentioned that the “squirrel cage” was turning
at no-load. Of course, there is a hefty load when producing electricity.
This means that the turbine would have to be much larger in diameter.
No doubt even large size units can be produced at a much lower cost
than the standard bladed horizontal shaft units we often think of on
Vertical shaft turbines of various sizes could be mounted on roofs, in parks, on hilltops or even on floating platforms out at sea.
While we’re thinking about out at sea, how about putting some of them
under water to take advantage of waves, tides and currents.
Actually, how about doing something like this in some of our major
rivers? They could be placed so they wouldn’t silt up or cause problems
with navigation.
