You can go even further Rafal. You could run the system for a while
on a negative energy balance. Its not like we are short on supplies
of plutonium or other hot radioactive wastes that could be used to
melt the granite, freeing the hydrogen. You could kill two birds
with one stone -- get a clean fuel and sequester nuclear weapons
materials and nuclear waste at the same time... :-)
Ohhhh, Spike, how much granite could we melt (or make moderately soft)
with 100 tons of plutonium?
I didn't read the article -- I'd tend to think you would find
more hydrogen in sedementary rocks rather than igneous rocks.
Thoughts?
Robert
