[LINK] 'Wire-free' electricity juices mobile devices

[Peter L. Higgs]

I suspect this is similar technology to that which cordless 
toothbrushes have used for years.. Basically contactless induction 
loops in the base and holder.  Having taken a few apart it is pretty 
simple.. Dont know how it scale up to 1.3 amps which is what some 
portable require for recharging.

What happens if you put you amex card on the base.. or your metal 
wrist watch???
