We can yap about technology but it's all out of our hands. Nuclear fission has 
taken permanent hit because of its cost$. It's not safety that halted uranium, 
but money. In a darwinian fashion, natural gas has superseded  uranium, from a 
cost-price ratio. Could fission or solar re-take the hill top any time soon? 
Will fusion ever be there? Don't know, and since I have no power to influence, 
don't care.

Mitch, in case you didn’t notice the US tight oil and gas sector is in a tail 
spin, reeling from the current wild price swing for oil & gas. This will swing 
the other way eventually and oil will rise above $100/barrel, but for now it is 
wreaking havoc on upstream projects. In the oil and gas sector there are very 
long upstream time lines and large capital outlays that depend on future prices 
being predictably above some predicted floor. Capital is fleeing this sector 
right now; as are the jobs. It will be interesting to see how it plays out over 
the next few years.

I know that.

Slowing the neutrons is also called cooling them.

And so is Helium and liquid sodium.
