> Or if one really cares about the loss, use direct current

I thought direct current had higher transmission losses vs AC

AC has higher losses over a transmission wire because of the changing magnetic field that it induces which creates losses.

There's a cool effect where if you hold a fluorescent tube under a high voltage power line, capacitive coupling from the varying electric field causes it to light up. Some energy is continually leaking out via this route, the tube just reveals it. (Magnetic induction too)
