Italian company based in Milan holds a patent that describes the
TWIND technology based on the use of a couple of captive balloons at an altitude of 800 metres, on a rotating platform able to follow the direction of the wind and through cables working also as motion transmission element. A balloon opens the sail connected to it, and while this balloon is kept away by the force of high altitude winds pushing on the surface of the sail, the other balloon, at close sail, is taken on the vertical of the platform, drawn by the same cable connected to the first balloon. At the end of cable unwinding, once it is at run end, an automatic mechanism operates the closing of sail wings of the first balloon and it operates the opening of sail wings of the second; in this way the functions of the two balloons reverse, repeating the same dynamic.

Californian company based in San Diego holds patent that describes the
WINDPOWER project aimed at the use of the motors on the model of the helicopters that running the blades by the wind , rise to high altitude and simultaneously generate electricity in proportion to be transmitted to the ground through the Anchor cables they are connected.

Canadian company based in Ottawa holds a patent that describes the
MAGENN AIR ROTOR SYSTEM (M.A.R.S.) project aimed at the exploitation of the Magnus effect on a aerostatic balloon able to rotate on its axis and generate so power through a couple of alternators connected to the ends of such balloon.

Italian company based in Milan holds a patent that describes the
KIT GEN project aimed at use the Wing profiles that semi vaulting at high altitude as a carousel of kits to keep in altitude anchored to a big horizontal windmill whose anchoring ground cables both control the wings movements through computer and take energy by the movement of such cables.

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.
