Stratosolar
Stratosolar
is a startup corporation created to develop buoyant stratospheric platforms for collecting solar energy.
The current concept, "StratoSolar PV" envisions photovoltaic cells lifted above the clouds by means of lighter-than-air gas bags,
with up to 3.5X more power produced than ground-based solar arrays due to better exposure and also lower operating temperature.
The original concept was to concentrate and direct light concentrated by a buoyant cassegrain reflector telescope structure down a buoyant reflective pipe to the ground for use in conventional steam turbine power generation
