The mess of electrical cables that recharge our laptops, mobile phones
and PDAs could soon disappear altogether -- at least according to a team
of US physicists, who have shown how power can be transmitted without
wires using special "resonant" antennas. The researchers used the system
to power a 60-W light bulb placed two metres from a wireless
transmitter, and say that it could be scaled down for use in portable
devices without a loss of efficiency (Science Express doi:
10.1126/science.1143254).
Gosh, just 120 years after Tesla (who holds the patents) MIT
physicists discover magnetic induction and the tuned tank circuit.
Guess that's what keeps that place number one!
The next thing they need to discover is the FCC regs on intentional
radiators.
