While I was doing some research about wind turbines, I came across this really interesting - but unrealistic - idea about floating wind turbines...a great source of renewable energy that could be moved. And more importantly, they can climb to relatively high altitudes where wind-currents are slightly more intense, so more energy can be created. Would people have a problem seeing these things floating around in a wilderness environment e.g. places in Alaska?  Check it out: http://inhabitat.com/altaeros-energies-floating-wind-turbines-tap-into-strong-high-altitude-winds/
