Other than the fact that even deserts face night, there _is_ one reason why
getting solar power from space is preferable.

The rectenna farms can be placed fairly close to where the power is used.

In the case of a solar power farm in, say, the Sahara, one is talking about *very
long wires*. There's a problem with people stealing copper, although I suppose
you could use aluminum instead. Salt water is pretty conductive, and there's lots
of that handy in the Mediterranean - also, *iron* is cheap, although it's not as
conductive as other metals, couldn't that be fixed by using thicker wires (and
HVDC instead of AC)?
