Really? Published much about it?

Let's have a little think, shall we? The earth's magnetic flux density
has a maximum of around 0.07 mT. The linear velocity of the earth at
the equator is 40,000km / 24 hrs = 462 m/s. The absolute best you can
therefore hope to achieve with a homopolar generator is 462 m/s * 0.07
mT = 0.03 V/m.

A 20m mast will therefore give you a whopping 0.6V (maximum) to play
with.
