Future Closer: Space Solar Power

Solar Power generated from orbital satelites and then beamed down to earth is one of the 2 great future energy sources (the other being fusion) – and the most likely.

It is one step closer:

A former NASA scientist has used radio waves to transmit solar power a distance of 92 miles (148 km) between two Hawaiian islands, an achievement that he says proves the technology exists to beam solar power from satellites back to Earth. [Link]

The test was a proof-of-concept, but all great things have to start somewhere.
