Don't forget an ancient experimenter that wanted to transmit energy:
considerable amounts, by wireless!!! He wasn't stupid and was deadly
serious about this quest. Read his history!
His name was Nikola Tesla who spent untold amounts of money trying to do
just this! He wasn't successful except over very short distances and the
efficiency wasn't good.
So don't get your hopes up.
Tesla revolutionized the AC electric generation and transmission system
with Westinghouse bankrolling him and made the polyphase AC system the
cornerstone for all the systems on the "grid" today except for the small
amount solar and wind power contribute at this time. There really isn't a
technology that will outdo steam turbine power generation except perhaps for
nuclear plants which can become runaway hazards as demonstrated by 6 Mile
Island and Chernobyl Russia meltdowns plus the tsunami upset nuclear plants
in Japan! Engineers and ecologists still haven't found a way to safely
store spent nuclear fuel rods without them having the possibility of
becoming toxic and extremely dangerous in the future.
Transmitting megawatts of power versus just a few watts wirelessly are
horses of two completely different colors in spite of what the "dreamers"
say.

I can't post on the site but I'd like to ask about the EMC conformance of
such a device, another PLT saga coming up.

Chargers for small electronic devices that use low frequency induction at
close range are common and harmless.
But how about a device that is said to use many transmitters to focus
energy
at a rate of 1 Watt onto a device that is 30 ft away?
Harmless??
