3 Motivation & GoalsIncreased access to electricity, water, power in developing nations must be provided in a sustainable way using renewable energy sources, such as wind powerDevelop a new renewable energy technology: Wind Power from KitesBuild prototype capable of generating ~1KWSlide Notes:1 KW enough to power most modern appliances (average US home uses 1.5 KW)Cost: 1 KW wind turbine generator costs about $10,000 to build. Also very complex as opposed to relatively simple design of kite power conversion mechanismEfficiency: Wind turbines only useful in Class 3 wind zones (avg. wind speed > 14mph), only ~10% of developing world. Kites can be efficient in Class 2 wind zones since they can go higher than turbines where wind speeds are greater. This allows much more of the world to benefit.Environmental Issues: Visual – turbines are big and dumb looking, kites are small and unnoticeable. Sound – turbines are loud (~ dB for small turbines), kites are quiet and mechanism is close to ground so sound doesn’t travel as far. Birds – 33,000 birds killed by turbines every year in US, kites haven’t killed any birds that we know of.
4 Wind Power from Kites Prototype Converts up-and-down motion of kiteinto electricity that is stored in batteries

6 Advantages of Kite Power for Developing Nations Potentially cheaper than a wind turbineMore economical in low wind speed regionsHigher wind speeds at higher altitudesKites can fly “faster than the wind” – apparent velocity effectMore aesthetically pleasing &environmentally friendly than wind turbines
