Although it's still in the research phase, Saul Griffith's company Makani Power is developing a way to generate electricity from kites. While we are all familiar with wind power generated from giant turbines, Griffith says, in his TED talk
, that there is much more potential for energy production using free-flying wings, such as kites, than turbines because free-flying wings can sweep through more sky and generate more power than a turbine in a unit of time. Additionally, free-flying wings have the potential to go higher than turbines, thus reaching areas which have more wind, and thus more energy-generating potential. The kites are variable in size, with something the size of a paper plane generating enough to power a cell phone and larger versions generating enough to power houses or even entire communities.
Off grid, scalable, with enormous potential.
