Was this written on April 1st? You need a transmitter and a receiver to
replace a few feet of copper wire? And two coils of copper tubing two feet
in diameter? There would have to be significant power from the transmitter
to make it work - the lamp would require at least 20 watts at the
receiving end if a fluoro, more for incandescent.Transmitter 50%
efficiency at best, losses over the path even though short.They are
kidding!
They certainly could not use 10 mHz it would have to be in the gHz region
because of antenna size.
Many of u7s as amateurs have used a fluoro tube to show we were on air in
the bad old AM days and used a pea lamp on a loop to resonate our
multiplier circuits on VHF and UHF, but light a room with it? There are
cheaper ways of doing it even with modern technology.
Who are they kidding? Hoax? Can't trust the internet, too many jokers
around.
