Observable universe output |
Goal: 10kw/person, 10 billion people (100TW), 1 million years
Coal/gas/oil? No way.
Terrestrial Solar: US sized area, efficient planetary power grid, terawatt-scale storage. Maybe.
Terrestrial Nuclear: 1 billion year supply, lowers background radiation, but incompatible with sensationalistic journalism. Maybe.
Space Solar: Vastly more energy available, no competition with biosphere, leads to vast expansion of biosphere. Maybe.
