SSPS for Hydrogen Economy

Hi, Thor!

I should have know to ask you that question! Thanks for the answer.
Precipitations out of a batholith... Hmmmm, would that make for radioactive
tourmaline? That mineral seems to have just about every other element in it
- why not a little U. However, I would still like to get an idea on how much
energy is practically available for nuke plants - how much of civilization's
energy needs could be met before depletion?
