If God or Tod forbids Bp fusion it is more ways to obtain neutron free fusion threw He3.
DD fusion may be used in big power facilities equipped to take care of radioactive waste and tritium. These facilities can also extract the produced He3 and distribute it to DPF devises located near the humans.
He3 may also be mined on the moon, but this may be a large step.
It would be interesting to hear the researchers ideas of a plan B.
