I doubt it, when you consider manufacturing processes (they have to be built, and they don't last forever), heat balance (the right place to put a solar array is in the desert, where most sunlight is normally radiated back out into space), storage systems (since the sun doesn't shine 24 hours a day every day), and the truly immense areas needed to produce large amounts of power. Actually, solar power satellites solve most of these problems; they might compete with nuclear for minimum impact. > We are not really looking only for the least impact, > but also one that is below a level that we can consider as unacceptable. > Like I said before, No way may be totally feasable.

The only feasible ways to reduce the population of Earth in any sort of hurry are a major nuclear war or a Third-World famine so drastic that it would probably result in a major war. We are stuck with the problem for the moment. And the only really effective way to halt population growth is to industrialize the Third World, so that the resulting economic changes will slow their growth the same way it slowed ours. So our near- term power needs will grow, not shrink. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
