Why space colonization never happened as envisioned

optimisticly, most fossil fuel reserves will be gone in 30-50
years, and there is a real chance of the production peaking in not more than
10.

No, there's lots of coal out there, and using it will still be cheaper than
SPS, tho all the natureworshippers will need to be told to sit down and shut
up.

I agree though, SPS R&D needs to be done *now* so we will have it when we do in
fact need it.

You're forgetting nuclear as well. There's enough uranium to last at last
150 years if not more. Beyond that, fusion will most likely be a reality.

Actually, there's 6000 ppb of thorium in the Earth's crust and
1800 ppb of uranium, totalling very roughly 10^30 joules to play with.
If you assume a civilization that consumes one hundred times more energy
than we do now, that's enough for over thirty million years and by the end
of that period we should be no more than thirty years away from commercial
fusion.

I've been noodling around with ideas for deep crustal mining,
too. There's an entire subterranian ecology down there that has not been
made human oriented yet, although the paltry amount of energy it has to
use limits what one can do with it.

per unit time! per unit time!

You can burn all the coal you want. Just make sure you don't create
CO2 and ruin my ski holidays (and much more besides).

I agree though, SPS R&D needs to be done *now* so we will have it when we do in
fact need it.

We could certainly start with some useful research instead of all the
stuff their currently not doing on ISS.

If your ski holidays are weighed against the power needs of the masses, you may
have to spend some winters at home. Or travel farther to find the snow.

If in fact ISS can even provide such research. My guess is it will require an
entirely new station. But yes, we need to start, and about ten years ago.
