How is the electricity initially generated? Does it come from “Nowhere?”
Will there be happy idiots working for free at the power plant where it’s generated?
There’s no such thing as a “Free Lunch.” There’s a cost somewhere down the pipe.
If the transfer was by radiation, then the second coil would be an antenna and the power loss would be much greater.How do you make that deduction?
One of the most efficient 'decoupling' mechanisms used to send 900 MHz energy up a 'live' AM tower makes use of two parabolic dishes several feet away from each other point at each other ...
A certain Slovenian would be proud.
I mmake that deduction because the device in the story is intended to be omnidirectional.
UNPLUGGED. Alternating current fed into a wire loop (blue) generates a field that induces currents in the coil (red, at left), creating a magnetic field that reaches a second coil (red) several meters away (at right), creating a local field that induces a current in the second loop (blue), lighting a bulb. -- Science
