Wireless power a reality (Jun 7)
http://physicsweb.org/article/news/11/6/5
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).
my toothbrush already does this.
MIT is about 90 years too late.
