Claim:
1. A system for storing and releasing energy from a platform in the low stratosphere comprising: a buoyancy component having sufficient buoyancy to retain said platform in said low stratosphere, said platform attached to a first end of a tether, said tether attached to the ground at a second end of said tether, a winch, said winch having a motor and a generator operatively coupled to a tension member, said tension member further coupled to a weight, said winch capable of adjusting a position of said weight with respect to said winch by raising and lowering said weight by said tension member when said system is in said low stratosphere, said winch configured for receiving energy from an external source to power said winch motor and raising said weight, and using said energy to store potential energy resulting from said weight to produce electricity by permitting said weight to fall at a controlled speed to mechanically drive said generator.
