Japan Plans $21B Space Power Plant

Mike writes "Japan has announced plans to send a $21 billion solar power generator into space that will be capable of producing one gigawatt of energy, or enough to power 294,000 homes. The project recently received support from Mitsubishi Electric Corp. and IHI Corp, who are now teaming up in the race to develop new technology within four years that can beam electricity back to Earth without the use of cables. Japan hopes to test a small solar satellite decked out with solar panels by the year 2015."

Since human bodies are mostly water, you're not going to absorb very much of the stuff, and what stuff you do absorb will be no different from being on the beach on a sunny day.

      If the military wants to weaponize the basic technology, they're going to have to design with it specifically in mind (even if it's possible to use microwaves for this purpose, which it probably isn't). They won't get a useful weapon using the civilian power system. The civilian system might help increase launch capacity and thus make the weapon system cheaper to build, but again, that's no different from any other space activity of this magnitude.
