89 Year Old Man Develops Bladeless Bird-Friendly Wind Turbine

The Catching Wind Power (CWP) Compressed Air Enclosed Wind Turbine:

“Traditional three blade turbines knock the birds out of the sky
because the birds can not see the massive, spinning, blades that turn
between 80mph and 190mph, therefore hitting them and knocking them to
the ground, killing them. Our design does not have any external moving
parts to hit the birds. Our unit is easy to see so the birds can avoid
it, and all moving parts are internal. The blades are mounted behind the
windsock and inner compression cone, therefore making them
nonaccessible to birds. Also, our turbines make virtually no noise.”
