New Compact Turbine Could Triple Wind Power Output

Normally wind turbines lose up to 39.7 percent of potential energy because wind not only flows through the blades, but is also directed away from the turbine. The new FloDesign Wind Turbine takes cues from jet engine designs in order to minimize this wasted energy.[social_buttons]

The company has enshrouded the moving blades with a set of stationary blades that propel the wind towards the rotor. The idea is not new, but previous designs have needed to constantly be aligned with the direction of the wind. The FloDesign turbine can automatically align to the wind direction and has been tested to be effective from up to 20 degrees away.

Conventional turbine design requires gigantic, slow-moving blades in order to compensate for the energy lost as the wind is directed around the device. FloDesign claims their new turbine can generate as much energy as a typical turbine twice its size.

Using these smaller turbines, wind farms could double or triple their efficiency simply by adding more turbines. The new technology could also finally silence critics of wind farms who say they are a cosmetic blight on landscapes and ocean views.

Check out this video FloDesign has produced to explain the technology in detail, complete with hip soundtrack.

    I am an Aerospace guy with over 2 year experience in engine design. I really doubt this technology or even seems fraud to me.

    Energy is extracted from momentum change in air. Now one can put a diffuser which is more or less like a frustum with the propeller at the end with smaller radium of the frustum so that it catches larger area and which gains velocity as area reduces (tricky).

    Here you don’t have anything in front of the propeller and they have put cowl after the fan…hell why are they worried of wind after the fan…u r not extracting any energy out of it anyways…thats stupid

    Stator is something that help align the flow over rotor so that you have smooth flow, when u have multistaged turbines. why does any1 to spend any1 on stator.

    Sounds too good to be true. Flow – Design please build one, operate it, measure wind speeds with a three-cup anemometer, and measure the output power. Publish the results in a peer reviewed Journal for all to see.

    Spain was able to recieve 43% of their electrical needs from the power of wind. MIT study says wind could power the whole US.

    Doesn’t ANYONE research these wild claims? The upper limit of power available from wind is known: 59 percent.

    “Normally wind turbines lose up to 39.7 percent of potential energy because wind not only flows through the blades, but is also directed away from the turbine.” That is how turbines extract power: the change of momentum from the change in direction. This is basic physics, people. These people are scam artists looking to extract your money more efficiently. You might as well invest in deposed African dictators.

    What a load of cods! Wind power will never be enough to signifigantly meet any realistic energy demands now or in the future. The energy density is just not high enough. Oh sure you can run a few lightbulbs but what about machine tools? Wind power is crap! The only realistic energy technology in nuclear. That is it. Nothing else will do it!!
