SSP – cheap clean energy from orbit

Wouldn’t it be great if we had access to a cheap and clean source of energy that did no damage to the planet and provided no reasons for wars? It sure would – and Al Globus has an article over at that suggests a solution that will be more than familiar to the veteran science fiction reader: solar satellite power. Unusually for space advocacy, he’s using sound economic and sociological arguments – perhaps if enough of us start suggesting this sort of thing, it’ll actually happen some day.
