“…9)) is ideal for high-efficient direct conversion into electricity with minimum heat pollution or after redirecting of the alphas with magnetic fields for space propulsion. However, it was evident from the beginning that this fusion reaction is very much more difficult than using DT fusion fuel, as seen from the spherical laser compression of p-11 B needing densities of 100,000 times the solid state (Hora, 2002) and input laser pulses of several 10MJ energy to produce modest energy gains per laser energy of less than 25 (Scheffel et al, 1997).
