My question does not in fact make the assumption that energy density is the only factor to transition from one fuel to another. Your response however does...... Answer the question.
I did not say that one energy source in exclusivity. In fact I pointed out the energy sources are used to compliment one another.
I did say that electric cars will never dominate.They will not. The laws of thermodynamics and physics determine this... It has nothing to do with whatever you or I think.
Once again saying that I said something that I did not say.
I think you should take some english comprehension studies and the go and do some research on the nuclear industry in general including fission vs fusion thorium, etc.
You are correct I did not bring up saftey. Safety was not part of the question and was not needed to be.
Once again it is something you dreamed up.
Stick to the question.
The saftey issues from the cradle to the grave for anyone with more that two brain cells to rub together are self explanitory.
