The HBll reaction resulted in radioactivity is lower values than from burning coal per generated energy. This was based on the very rare experiments with extreme suppression ofpre-pulses in order to suppress relativistic self-focusing. Subsequently, acceleration of highly directed plasma blocks of modest temperature and ultra-high ion current densities above 10H Amps/cm2 were measured in agreement with earlier derived theory. This permits the conditions of the Chu-Bobin for side-on ignition of solid density fusion. Results for similar neutron lean He3 are reported. A detailed comparison with the usual spherical laser compression and ignition of fusion is given for clarifying the basic differences of the ignition process.展开更多
