The height growth of the traditional structures that include the aeolian generators is due to three facts:a) The speed of the wind grows with the height;
b) The hours of wind increase with the height;
c) The energy that can be produced by the wind increases according to the hours of wind and with its speed square.
In the aeolian generators, the speed of the winds and their last in time represent two factors of energetic output; anyway the planning of wind generators at horizontal rotation axis gives important limits of structural nature both in the diameter of the blades and in the height of the towers.
So a new frontier in the exploitation of the wind power was opens. It aims at the high altitude winds with technical solutions that are still in research.
The interest in it grows also because of the high altitude winds blow 7/10 days against the 3/10 days of the traditional wind generators.
