The current concept, "StratoSolar PV" envisions photovoltaic cells lifted above the clouds by means of lighter-than-air gas bags,[2] with up to 3.5X more power produced (per unit area) than ground-based solar arrays due to better exposure and also lower operating temperature.[3]

The original concept was to concentrate and direct light concentrated by a buoyant cassegrain reflector telescope structure down a buoyant reflective pipe [4] to the ground for use in conventional steam turbine power generation.

In both cases, minimal land use compared to earth-based photovoltaics is a stated benefit.
