I think we're all suspicious of fission, but if we can develop a
practical fusion reactor, we'll have clean power from hydrogen
fuel and with helium exhaust. Plenty of hydrogen out there between
the stars, they say.
I'm not convinced by that. A lot of the problem with nuclear is upfront
build cost. There is little reason to believe fusion reactors would be
cheap to build.
It seems more probable that we could develop cheap fast fission
reactors, which are both relatively safe and produce much less waste.
Not that the current level of waste is technically a problem, apart from
in some peoples minds.
The big problem at the moment seems to be political will. Politicians
can say we are moving toward zero carbon by building windmills and the
electorate buy it. It doesn't matter that it seems unlikely that
windmills will be able to provide enough power or reliable power.
At the very least politicians should be actively investing in fast
fission reactor R&D.
Plenty here on earth too, nicely stored on the oceans for us. So
it would do for earhtly use as well.
Plenty of uranium and thorium too.
