Electricity-over-RF has arguably been one of the favorite pipe-dream wireless technologies of 2007. There was a lot of fuss over the summer about an MIT team that managed to power a lightbulb using RF power.

Radio frequency power is at a very early stage; the technology is the kind of thing we'll probably be able to take seriously in five to 10 years' time. Still, the opportunity to cut the last cable is understandably fascinating for people.
