Exploring high-altitude balloons, atmospheric electricity, airborne wind, regenerative descent and atmospheric water as components of reusable energy cycles.
The project separates the source of energy from the mechanism used to transport, convert or store it.
Elevated collectors exploit atmospheric potential differences. Very high voltage is possible, but available fair-weather current is the central limitation.
Reusable balloons move payloads vertically with helium or hydrogen buoyancy, creating a platform for experiments across the troposphere and stratosphere.
A heavy descending vehicle can convert gravitational potential into electricity through rotors, generators or a ground-based tether system.
A vehicle that acquires water aloft and returns heavier can recover part of the gravitational potential already possessed by that atmospheric water.
Kites or tethered aircraft extract energy from stronger high-altitude winds and transmit mechanical power to a generator at the surface.
Instead of transmitting power continuously, batteries or other storage media can physically return captured energy to the ground.
One proposed cycle combines buoyancy with acquisition of mass at altitude and regenerative descent.
The energy balance must include the origin of the lifted or collected mass. Moving a mass upward and recovering it downward is energy storage, not net generation. A viable cycle requires an external energy source such as wind, solar radiation, atmospheric water already at altitude, or another environmental gradient.
Indicative engineering ranges rather than performance guarantees. Experimental concepts require prototype measurements before a meaningful levelized cost can be assigned.
