Kite Gen Research 3 megawatt prototype of a wind-kite operates at an altitude of 10,000 meters. Nine Kitegen generators would produce 27 megawatts of peak power.
High altitude wind is much more powerful and constant when compared to that at earth level, which is intense in very few places, and at full speed for only about 1,700-1,800 hours per year, which limits the annual production of energy.
The wind which is planned to be used is around 800 meters height with average speeds of 7 m/s and specific power of 200 W/m2. For example, a section of wind width of 1,000 meters at an altitude between 600 and 1,000 meters has a power equal to 400*1000*200 = 80 MW.
The prototype in the
The Kitegen can generate about 6000 hours / year.
