Paraterraforming vs. terraforming the Moon and Mars

geothermal is still cheaper and more accessible and even greener and by far higher in yield. I will design your solar sat tho if thats the next thing up, but , no, i don't agree. space solar is exorbitantly expensive and silly when compared to geothermal. Its useful to beam power to places out in space tho...not back to earth.

"or valuable materials mined from asteroids and returned to earth? Then the question is which path are we better suited technologically to pursue. I suspect, it is solar power."

uhhhmmm....errrr...

Uhm...

you know the real best use for such solar is to beam it out into the outer solar system or to smaller vehicles in route.

The whole solar thing is a total sideshow as far as i am concerned but
i will still draw solar sats if thats what you are ready to work on.
