Abstract
An energy collection system uses one or more airborne energy collection vehicles having a lighter-than-air balloon structure. The balloon structure has an outer gas envelope formed of a substantially inelastic material and an inner gas envelope at least partially separate from the outer gas envelope, contained within the outer gas envelope and separated from the outer gas envelope by a flexible diaphragm. The space between the outer and inner gas envelopes is filled with air. An air chamber pressurization mechanism maintains the outer gas envelope gas pressure at a target value. An energy storage facility receives energy from a photovoltaic collector array and converts the received energy to stored energy. Storage of the received energy can be accomplished by conversion of a precursor to a high energy fuel as the stored energy, by use of storage batteries or by storage in an inertial mass.
