| Space Solar: Vastly more energy available, no competition with biosphere, leads to vast expansion of biosphere.

Goal: 10kw/person, 10 billion people (100TW), 1 million years
Stretch goal: fill solar system, galaxy, and universe with life
Coal/gas/oil? No way.
Biomass: Polluting, destroys unseen material cycles, consumes all of nature. Worse than fossil fuels.
Terrestrial Solar: displaces nature, requires US sized area, efficient planetary power grid, terawatt-scale storage. Maybe.
Terrestrial Nuclear: 1 billion year supply, no competition with biosphere, but incompatible with sensationalistic journalism. Maybe.
Space Solar: Vastly more energy available, no competition with biosphere, leads to vast expansion of biosphere. YES!
