By the way... I know this is madly off topic, but why on earth has some budding entrepreneur not created a small solar powered server yet? It would just need a battery to keep it going through the night. Wouldn't that be nice? No wires.. no hassle, no going down when there is a power cut or current surge.
And of course it would nicely complement the solar powered Mifi router that is hanging on the lamp post outside where the HSDPA coverage is best!
Actually... I think the second idea is even better! I'm sure someone has thought about that by now!
