Intel Claims an Advance In Wireless Power
Many readers are sending in coverage of a demo at Intel's developer forum of a wirelessly powered 60-watt bulb. The NYTimes gives background on Intel's improvement to the 'wireless resonant energy link' technology pioneered at MIT, where researchers achieved 50% efficiency of power transmitted several meters via magnetic fields. Intel reached 75% efficiency. Now they just have to make those coils a lot smaller.
how about all manufacturors agree on a single plug for their power supplies. Then the companies who make power sockets for offices can make one built into a wall socket. Put that into every meeting room. Suddenly you just need a 1 meter long, very thin cable instead of a lugging a whole kilo of copper around....

Tesla wanted to do this on a large scale over a hundred years ago, and was prevented by the laws of physics.
Linemen also spend more time in the sun, are more likely to be exposed to PCB residues from transformers, and are exposed to chemicals like arsenic and creosote used as preservatives in wooden poles.
