Re: [energyresources] Re: Revolutionary Thorium Reactor

Alan,
   I have dug and dug on the net on this. Everyone knows
it should work and has known since 1953. But getting
that theory into commerical application has obviously
run into major problems that aren't being discussed, daunting
problems at that.
....Speaking of application...The drilling off the Brazilian coast
for the speculated 30B B oil deposit is encountering
problems also. While the first two test drills found indications
of oil in the salt dome, the third, at a cost of 125 million
came up dry.  There is guessing now that the oil may be
scattered in thin layers rather than pooled into one reservior
which would make extraction more difficult and expensive
than expected to date.

Good reply, thanks.

You write: "All will require long cycles of development
and testing before they can be certified and licensed
for production."

Why is this? Is it necessarily so? I presume you are
talking about government channels and hoops -- the
certifications and licenses. Are those channels and
hoops truly necessary? (If they are, fine; I'm just
asking.)

Also, why do you say that long cycles of development
will be required? Again, I'm not saying you're wrong;
just wondering what the basis is for the statement.
Are the "long cycles" secondary to bureaucratic
crap that could (at least theoretically) be quickly
cleared away? Or are there substantive engineering
issues that really will, inevitably, take a long time to
work out?

Alan

PS: I loved your last paragraph. Yes, "how we're going
to save the planet if depletion of fossil fuels isn't
going to do if for us." And I suppose next thing
you're going to expect us to start THINKING.
Damn! Slave-driver! ;-)
