[cma-l] Mains power where there ain't any!

[Glyn Roylance]

Certainly - Orange have a wind/solar radio site in the Elan Valley in Wales,
and another one with fuel cells in Scotland, and many hundreds of solar ones
in Africa!  A combination of alternative power sources is to be recommended
(not often much wind when its sunny and vice versa).

Mobile phone sites are really inefficient and need loads of power, so in
contrast powering a small FM transmitter should definitely be in the
do-abale category.  If power-down overnight was acceptable it would make it
even easier.

Probably not cheap though - then again neither are new power supplies to
remote locations.
