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 guess you can’t save a comment written before registering. Thanks for telling me …NOT!

    I have always found it funny that we worry about wind farms hurting birds( which they don\\\’t) But we have no concern for birds sitting on high voltage lines that produce enough electromagnetic energy that we won\\\’t live near them.

    Using the \\\”89 year old…\\\” lead to this story is drawing attention to the fact of his age, before his idea. This is contributing to the idea that older people don\\\’t/can\\\’t contribute or be a part of the world in general. Mentioning his age ,as an aside, later in the story, and not as a lead/hype/sound bite, would just be an interesting side note…and much better reporting. I\\\’m just saying

    This is an old wind concentrating idea that never worked. Pressure buildup behind the cone diverts too much incoming air around the cone instead of through.

    I agree it’s for the birds.

    The design has more to recommend it than saving birds and bats.

    It is far less obtrusive to the skyline which is urban friendly.

    Being quieter, it can be located closer to where people live.

    And I’m thinking it would be easier and less costly to install and maintain. No big transport trucks, flying cranes needed.

    The cones are modular and could be replaced more quickly and economically when they fail.

    The modularity also means they can be installed in large or small arrays as needed.

    @ Bob Mallen. It depends. If the species of birds killed are not threatened then your argument has merit. If, on the other hand, threatened species are killed, then something needs to be done about the design. There is some concern that windmills are killing whooping cranes. See:

    If this is about saving the lives of birds does this guy own 1 outdoor cat? Outdoor domestic cats are responsible for over 90% of bird deaths annually, wind turbines kill something like 1% of annual bird deaths. If this technology is more efficient than conventional wind turbines then I am behind it, but it appears to be fixing 1% of a problem, and that is fairly insignificant.

  9. davidray313 September 9, 2014 at 12:11 pm

    This innovation should be applauded. Reducing individual bird mortality is not insignificant.

    Only concern: that we forget to address the primary threat to bird survival: habitat fragmentation that effects entire populations. Often lost in the public discourse, but this is more significant in the long term than individual bird mortality from turbine blades. If we construct wind towers of any design in places that require us to fragment our best core habitat areas or breeding areas (this applies to forests, grasslands, and other habitats), bird conservation will not be accomplished.

    So, bring on the innovations; renewable energy is another necessary component of bird population survival. But couple it with strategies like the one that The Nature Conservancy calls “Development by Design”–putting them in the right places. Siting wind towers will always be tricky–some object to what they perceive as marred visuals, or to the mortality of individual animals. I would posit that preserving the ability of animal POPULATIONS to survive by preserving their habitat is a conservation value that virtually everyone can support.

    It appears a bird can fly into the cone and could then be mashed up like a blender. How will birds avoid the cones? How will it keep from turning to fast since it can’t fural it’s tail away from the wind at higher speeds or change the blade angles in other wind turbines?

    Let us know how the testing goes.

    Patented compression cone. It’s just a cone fer cryin’ out loud! Good application though…

  12. Audrey Fletcher April 6, 2013 at 5:54 am

    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.

  14. alternativejp September 2, 2012 at 5:04 am

    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

  15. bthinker September 1, 2012 at 12:46 am

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