If researchers at MIT have it their way we may, some day soon, be free of the wires that tie our electronic devices to their power supplies. Imagine your cellphone charging on it's own without being required to 'plug in', or your laptop working without a battery or an AC adapter. Scientists have known for centuries of several methods of moving energy around without wires, but these methods are either inefficient or potentially dangerous to human life. The MIT researchers have been able to exploit the fact that two resonant objects of the same resonant frequency tend to exchange energy efficiently (the link above has a great explanation). Apparently the science is based on well-known laws of physics and could have been explored long ago had there been a demand for such requirements. While I am in awe of the thought of such developments, I think I'd like this to stay in the lab until we find out that it is really safe to be walking around in. Maybe these guys can get back together for a picture in a couple of years time...
