Proton-boron (pB) fusion has long been seen as the grail of energy production for mankind. Indeed, the reaction (p + B11 -> 3 He⁴ + 8.7 MeV) does not produce neutrons, unlike the deuterium–tritium fusion (D-T) reaction, implying little activation of materials and hence a very low amount of radioactive waste.
