Wireless Power ~ Key Transmission Innovations...

"The Japan Aerospace Exploration Agency (JAXA) has in fact already been developing one possible solution: space solar power (SSP) -- beaming energy to Earth from a satellite in orbit. With its Space Solar Power Systems project, JAXA researchers “have started preparation for the world’s first demonstration of 1kW-class wireless power transmission technology, and are aiming for practical use in the 2030s."

The article goes on to cite prior art, including 1975 NASA JPL Goldstone Demo of Wireless Power Transmission... Also very interesting are shorter-range MIT spinoff efforts at WiTricity... Even simple wireless power transfer via inductive pad is interesting.
