Wind driven apparatus for power generation

Wind driven apparatus for the production of power at a ground location comprising

• vehicle means responsive to the motion of surrounding air for generating lift and maintaining a stable airborne orientation, said orientation comprising periodic oscillations through the air;
• means carried by said vehicle and responsive to the relative motion between the air and said oscillating vehicle means for extracting mechanical power therefrom;
• means carried by said vehicle for converting said extracted power to reciprocating motion;
• and
• tether means linking said vehicle means to a ground location and defining the maximum radius of said oscillations, said tether means including for both bearing the entire tensile stress imparted by said vehicle means on said tether means and for transmitting said reciprocating motion along said tether means to said ground location said means for bearing said tensile stress and for transmitting said reciprocating motion comprising a plurality of members connected between said vehicle means and said ground location and mounted for reciprocation along said tether means, each said reciprocating member having a phase relation with respect to said reciprocating motion which is different from that of any other said reciprocating member.
