Mountain top Kitegen could tap winds 24 times stronger than conventional

The kitegen system could radically improve the situation a promising outlook for wind power. Winds are stronger and steadier at 800meter and up. Building on mountains and hills would provide access to even stronger and steadier winds. Winds that are up to 24 times stronger than current winds at 80 meter altitudes. The Kitegen system would have to be adapted to pull energy from gale force winds on mountains. I believe that the Kitegen system is suitable for using many kites to pull a large ring shaped turbine.

Wind speeds on average in the Himalayas are 75mph (33m/s) and can reach more than 100mph (45 m/s). The windiest place in the world is Mount Washington (1,918m) in New Hampshire, USA. On 12th April 1934 a surface wind speed of 231mph was recorded.

Mountains cover 54% of Asia, 36% of North America, 25% of Europe, 22% of South America, 17% of Australia, and 3% of Africa. As a whole, 24% of the Earth's land mass is mountainous. The Himalayas average 5 km above sea level, while the Andes average 4 km. Most other mountain ranges average 2 – 2.5 km.

Kitegen has wind data showing that at 5600 meters of altitude there are many locations with 15-20 m/s wind and at 10500 meters there is 35-45m/s wind Accessing those winds with kitegen systems on mountains would increase wind power by 3 to 6 times over the four times improvement that 800 meter winds have over 80 meter winds. So 10,500 meter winds are 24 times stronger than 80 meter winds.

Conventional New Wind Energy Forecast
I believe that Nuclear power can be scaled up faster than wind. However, wind power is doing quite well and it is and will be significant.

73,904 MW total installations as of 2006, expect 90,000 MW by the end of this year (2007). This 2007 total is equal to about 30GW of nuclear installation because of operating load. Germany has over 18,000 turbines with avg size of a little over 1MW. the latest installations are 5MW and 6MW units. By 2010, the World Wind Energy Association expects 160GW of capacity to be installed worldwide.

The 28GW build rate at the end of 2010 carrying forward would add 280GW from 2011-2020. After 2010 the size of new wind turbines will be 7.5-10MW and probably still getting bigger.
