bit of p

Some one on this list (Monte?) brought this up (Tesla's version) a
while ago, and it was pointed out that it has always worked, but that
efficiency drops quickly as distance from the power source increases
(the article cites 40% efficiency, but doesn't mention distance).  Not
a very useful breakthrough at that efficiency.

The team from MIT is not the first group to suggest wireless energy transfer.

Nineteenth-century physicist and engineer Nikola Tesla experimented
with long-range wireless energy transfer, but his most ambitious
attempt - the 29m high aerial known as Wardenclyffe Tower, in New York
- failed when he ran out of money.

"This was a rudimentary system that proves energy transfer is
possible. You wouldn't use it to power your laptop. The goal now is to
shrink the size of these things, go over larger distances and improve
the efficiencies," said Professor Soljacic.
