would let him transmit power to any point on Earth
if he could make Earth’s potential resonate.
Early attempts to invent radio transmission
caused confusion between electromagnetic induction (which
is used today only between nearby wire coils) and
electromagnetic radiation (which can travel long distances).
I wrack my brain for other forms of energy
that we could harvest with rectennas.
I’m wondering, “Virtual particles?”
So many are whirring about from quark to quark!
William C. Brown’s design for a rectenna featured diode bridges
producing a continuous pulsed direct current.
The difficulty in producing optical rectennas is that even the fastest diodes today
cannot handle the high frequencies of light waves.
