This is an idea that occured to me about 2 decades ago & seems to be
making even more sense now in the wireless internet generation.
We already send radio analog waves through the air.. and we also send digital waves through
the air such that your laptop computer receives it's own internet connectivity using an IP address/MAC address specifically assigned to it.
Why not crank-up the amps on the amount of power being sent but have it pulsed or packeted so
that it's enough for a 110V supply for a remote appliance & doesn't fry people along the way?
All the remote appliance would need is a small recheargable battery to start it's receiver.
Once it picks up the "power wave" assigned for it's IP/MAC, then the power wave would take
over and run the appliance while the battery charges.
I heard from the net that there are some small groups of people working on this concept.
I'm guessing in about 30 years, this will be a reality.

Tesla was doing it back in the early 1900's, running electricity through breakers without a direct link to them, i.e. through the air. He wanted to supply the world with this wireless energy for free. The powers that be thought differently about the idea.
Look up Wardencliff and Scalar Energy, if I'm not mistaken I think the technology eventually became HARRP, the scalar weapon array in Alaska used to control weather.
