High Altitude Wind Energy

Came across this interesting TED video on high-altitude wind energy. Its amazing that we are just scraping the surface of alternate energy. We are just getting started with wind power as an energy source and currently less than 1.5% of world's energy comes from wind. This is one of the most rapidly growing alternate energy source. Along with solar, wind represents the only renewable source of energy that is substantially larger than the world's current energy needs(72TW capacity vs 15TW global consumption today).Most of the wind energy we are harnessing today is in the lower atmosphere (ground level) where the efficiency is low. This video talks about harnessing wind power at higher altitudes. This is a green field technology with high potential.

High-altitude wind energy has the largest energy per square foot of all of the renewable energy technologies (wind, solar, tidal, hydroelectric, biomass, geothermal) and a very low cost. Capturing a small fraction of the global high-altitude wind energy flux could be sufficient to supply the current energy needs of the globe. This is achieved through the use of high altitude kites & Air-borne wind turbines. Technologies exist today to harvest this in a large scale and this has potential to change the energy landscape.

About this talk

In this brief talk, Saul Griffith unveils the invention his new company Makani Power has been working on: giant kite turbines that create surprising amounts of clean, renewable energy.
