What would happen if an organization put something into LEO in the ionosphere and keep it in geosynchronous orbit with a receiver to beam a laser to the location for wireless power transmission? Could an optical tether be built between the two that would allow for high-efficiency energy transfer?
The energy it would be capable of producing would rely on its surface area relative to its tangential velocity. Cost would be whatever unit of cabling versus budget of making it micrometeor resistant.
