I would suggest that an aneutronic contender should be a device of which at least one physical iteration has actually been built and tested, and that reasonable extrapolation of the results of such tests suggests that at least the D+He3 reaction is feasible. Or, if that is too strict, at least a simulation of the device, or some sort of mathematical calculation, should demonstrate its potential feasibility. I would also suggest, particularly given the current paucity of threads in this particular forum, that it might be best to create a new thread to introduce each aneutronic contender and allow us to consider each one separately.
