ABSTRACT:
A device which lifts itself into the air and either itself carries a windmill for the extractions of power from the wind, or traverses a oscillatory path back and forth across the wind such that the action of the tethering lines for the device can be used to generate useful power such as electricity is disclosed. A series of airborne structures, an autogyro-helicopter, the paramill, and a sail plane are all disclosed as the self-erecting structures. Power is extracted either within the airborne structure, preferably by electric generators, or from the tethering lines through the use of certrifugal or other pumps, or electric generators. Stability and control of the self-erecting structure is accomplished via the use of servomotors or control lines directed from the energy extracting site through the tether to the erectable member.
