The Pentagon is toying with the idea of space based solar arrays accoring to MSNBC. The arrays would allow the military to power their equipment in remote locations, as well as provide power at all times of the day. The whole project goes under the 'maybe' category at the moment with Michael Hornitschek, part of the Air Force staff at the Pentagon, seeking funding from The National Security Space Office (NSSO).

The project sounds similar to an idea from the L5 society in the 70's. Although the L5 idea was to build large human colonies that would beam energy back to earth.
