This entire wide-area wireless power idea occasionally keeps rearing its ugly head. It doesn't seem to matter that the physics says that it won't work or that no one has ever made it work in 120 years. And yet it keeps coming back like the birds returning in spring.
It's not unique to Tesla - Beaming power from space seems to have resurgence every 15-20 years. I think it's when the engineers who figured out it wasn't really practical have moved on to other jobs, and a new crop proposes it, gets funded to study it (this time we've got new technology X), and then someone explains how expensive it is to put things in space. 

There's no getting around the inverse square law.

The physics involved here, at least according to Nikola Tesla, are
different from the physics of radio transmission. I'm not defending world
wide power transmission with Greg's design, but I am defending Tesla's
understanding by saying that electric field transmission involves
longitudinal radiation in the electric field, as opposed to transverse
radiation in the electromagnetic field. The inverse square law does not
apply when resonance develops mainly in the electric field. This was a key
concept that Tesla designed his wireless transmission coils around, and
Tesla went to great lengths to make this concept clear.

True longitudinal waves would require an insulated transmitter with just
one pole, impossible to build. With the structure of a Tesla coil the
electric field soon bends to the ground, resulting in the usual
transverse waves. And in both cases there is decay of power as the
distance increases because the power is the same but the area is larger
with more distance. Simple geometry.

Keep in mind that Tesla was physically transmitting power wirelessly at
Colorado Springs to the distance of miles, and not just tens of feet. But
that is not what this experiment is about.


There is no documentation of anything transmitted at more than a few
meters, originally or in attempted reproductions over more than a century.
