Makani Energy Kite - A Google X Project

Alternative energy technologies are a hot topic as of late.  The oil and gas industry has been tanking and there is a growing focus on the impact of fossil fuels on the environment. Then there's the issue of fossil fuels being obtained from pre-historic fossils which are a non-renewable source and depleting at an increasing rate.  The list goes on and on; oil spills, the need for reserves, coal mining, acid rain.  So the million dollar question is, how do you make energy a sustainable, clean resource?  Makani, a Google X project, are investigating the possibility of kites that collect energy through a turbine blade.  As air turns the kites turbine, a generator sends electricity to the grid through a tether.  Check it out  A fan of fossil fuels or not, this is pretty spectacular.
