solar furnace in space = unlimited clean energy?????

Welcome to able2know odinpop: A very large solar furnace orbiting 200+ miles (about 12,000 miles might be best) above Earth's surface would produce a powerful beam of sunlight, but most of the Energy would scattered before it reached Earth's surface.
Carried by a balloon, twenty miles above Earth's surface, a solar furnace might be able to deliver more than 10% of the energy to a large solar site on the surface.
Alternately the powerful beam could boil water to make high pressure, high temperature steam to drive a steam turbine to turn a generator to make electricity that could beamed by microwaves to rectennas on Earth's surface. A $25 million study in the 1980s was not very encouraging, probably because each energy conversion envolves some losses, and the system in space would require contineous maintenance by humans, and some people would be unwilling to accept the possible minor health hazard of the powerful microwave beam, or laser beam which is another way to get the energy from space to the customers on Earth's surface.
