"Per unit energy D-T fusion, the fusion reaction most likely to be viable near term" Ok well, I see the use of tritium only as a step towards normal hydrogen as fuel in fusion reactors. Tritium as fuel is just the "easy" target and yes, it is in limited supply and causes problems. But "in theory" we could have higher temperatures and not be dependant on tritium.
