[ RadSafe ] Absurd? Oh, the irony!

[Muckerheide, James]

Lithium blanket?  breeds tritium; working fluid carries away heat to generate
electricity.

Does inertial confinement work differently?

The problem as I see it with fusion is that all the execss energy is 
given to neutrons.  In order to convert this essentially thermal energy 
of the neutrons into usable thermal energy we have to use uranium as a 
blanket to convert the energy into fission energy using the vastly 
greater energy of the fission products to convert to heat.  Lots of it.  
With that process we are back to all the problems we have today of 
radioactive waste.  The fusion process is pie in the sky until we talk 
about the real problem of converting the fusion energy into heat and 
then into electricity.

controlled nuclear fusion to squeezing Jello). And I would like an
explanation of how controlled fusion leads to nuclear proliferation.
