Fusion for power?? I am guessing that the Coulomb Barrier is the major problem??? What exactly is necessary to breach the Barrier, as far as the amount of energy, heat, velocity of proton, etc, etc. If the Barrier COULD be breached without destroying the city at the same time, what other problems are there? Converting the MeV inside the system into voltage outside of the system, maybe?? Keeping the reaction going for sufficient time periods? Interesting stuff!
