    A Guinness powered windbelt?

    Triboelectric nanogenerator harvests wind energy.

    Actually the above could be quite an important advance in wind energy, maybe kites into the jetstream?

    Wind power cost competitive with natural gas, study finds.

    Still the same old wind turbines why don't they try something like Sheerwind?

    Unusual design claims 600% more production in low winds.

    Wow, couple that with some advanced photovoltaics and you'll have thousands of percent efficiency. You could put the PVs on the edge of the turbine things and they would be even more efficient, meeting the photons at speed instead of just sitting on a roof soaking up the rays.

    Reminds me of when I asked on the old Steorn forum for opinions as to what would happen if two magnets of the same polarity approached each other at the speed of light.....

    Yeah... there will be just as many PVs receding as there are advancing, so there isn't any benefit to be had from violating special relativity with your photovoltaic-wind turbine.

    Well, I assume you were writing tongue in cheek in full knowledge of the fact that photons wizz past you in any and all directions always at precisely the same speed, irrespective of your speed wrt the source of the photons

    Ah...but what about their masses? The ones arriving from in front are Doppler shifted upward in frequency so they are more energetic and therefore have more mass. No?
  5.  
    Oops, yeah. Energy is frame-dependent, even for photons. That's why, as an interstellar vehicle approaches c, it sees increasing numbers of x-rays and gamma rays. E = p c, but p depends on frequency, which in turn depends on relativistic Doppler.

    Cthulhu-power. The Slimy Green Energy Committee in Dunwich is looking into it. Not advised for others.

    Engineers study the benefits of adding a second, smaller rotor to wind turbines.

    This Strange Stockholm Wind Farm Generates Power Through Writhing Tentacles.

    I like it, a tourist attraction that also generates power.
