Gallery: 89-Year-Old Man Develops Bladeless Bird-Friendly Wind Turbine!


Wind turbines transform moving air currents into clean energy; there isn’t much to hate about that, especially when compared to the toxic emissions and high cost of fossil fuels. But wildlife conservation organizations have often expressed concerns that wind farms pose a threat to flying species bird and bat species. Eighty-nine-year-old military veteran Raymond Green decided that there’s no reason why clean energy and birds can’t coexist, so he designed the Catching Wind Power device, a bladeless wind turbine that promises to harness wind energy without harming our feathered friends.

Green’s CWP Compressed Air Enclosed Wind Turbine completely eliminates the three massive blades seen on most wind turbines. Rather than waiting for the wind to turn a blade, Green’s device features a patented Inner Compression Cone Technology, which he claims will squeeze and compress the incoming air in order to create more power at the turbine.

“Our design does not have any external moving parts to hit the birds,” writes Green on his website. “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.”

According to Green, his design can be scaled up for commercial power production, or down for residential use. The CWP will soon be tested, improved upon, and manufactured by Sigma Design, so final judgement will have to be reserved for the birds themselves.

    I like this idea, I like that it could be made for home use!! Now what if the cone is made of flexible solar panel? best of both worlds???
    I have been thinking about the fake trees that are set up for cell phone tower for a while now… What about the teen that developed the tree like solar panels rather than the big flat ones. he based it on Tree and plants are the best solar panel designed by nature. why can’t the fake trees have these kind of leaves to take in power too.

    this is a genius product. low frequency noise coming from the wind turbines seems to a real problem. killing birds is never good. This product fixes everything. I hope to see them everywhere soon… I’m mean it, really soon.

    Have you thought of ading refection stationary blades in the mouth of the cone that will cause a vortex to the wind that enters the cone, Had this cone idée for years but never got around to build one

    I’d like to see more on the patented compression cone. Sounds like an interesting design. Good find.
