• Nuclear reactions produce ten million times more energy than the chemical reactions e.g. from burning carbon, but the equilibrium thermal pressures for chemical reactions need temperatures of hundred °C while nuclear burns need many dozens of million °C. This is on the level for ITER or at NIF with using nanosecond laser pulses. In contrast, non-thermal pressures can be higher by lasers using nonlinear forces of picoseconds or shorter duration as computer results of 1978 had demonstrated by non-thermal plasma-block acceleration. This is in full agreement with the ultrahigh acceleration measured by Sauerbrey since 1996 thanks to his use of ultra-extreme powers of picosecond CPA-laser pulses. Even the very inefficient classical fusion of hydrogen with the 11B can be used for the non-thermal reaction with sufficiently modest heating in a reactor for generation electricity.
