Gives details of power transmission without wires. This story first seems to
have broken in November last year, but they have moved up from charging
mobile phones to lighting a 60 watt light bulb.

Apparently the system works with efficiencies of up to 40%. Wow! The power
companies must be getting desperate, with low wattage lighting and LCD
displays using so much less power than before. Makes me wonder what the
other 60% is going to be cooking, me or the ozone layer.

Looks like an opportunity for some enterprising entrepreneur types to invent
a more efficient transmission and receiving system - I suggest straightening
out the wire coils and connecting the light bulb directly. That should
improve power transfer efficiency to over 95%.

the 60 percent rest is burning water

Mike,
I think that has some sort of connection to a Poyntings vector where
the vector
does not escape to the outside area but is consumed by an energy sink
that is part
of the field within the enclosing loop that is in equilibrium. It is
difficult
to see how they managed to get the laptop resonant such that its
energy sink capacity
balanced with the internal electromagnetic field but they did say
there was some EMI
Those guys at MIT are really clever people. Next project is to get
water to ignite
and simulate what that guy in Florida is pursueing.

Very droll.

Space shuttle launch on NASA TV was good though. Now that IS what I call
rocket science.

Most likely the front end of your reciever if this idiotic idea ever
gets implemented.

Most of the charger thingies I have around the house are in the 2-5 W
range.

2 W at 40% means they have to radiate 5 W.

Perhaps a grazzing antenna would improve the efficency.
