1. A windmill kite for converting the kinetic energy of high altitude winds into useful work or other forms of energy, the windmill kite comprising:

  • at least three substantially axially co-directed, spaced apart mill rotors mounted into an assembly or unit;

    a platform frame conformed for supporting said mill rotors being tiltable upwards a predetermined angle with reference to a substantially horizontal plane;

    at least one tether line maintaining a substantially fixed geographical location of said platform;

    at least one winch at ground level enabling the kite to be reeled in or let out in order to adjust its altitude as needed at least one dynamo mounted to said platform and connected to an output of said mill rotors;

    a conductor connecting said at least one dynamo to an electrical supply at ground level;

    an electrical system controller to allow electrical energy produced by said dynamo to be distributed into an electrical system; and

    a platform positioner mounted to said platform and configured to control the pitch angle on blades of said mill rotors to maintain the attitude of said platform relative to a fixed set of orthogonal axes.
