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.
