How would we make energy out of Helium 3 from the moon? What's so special about it?

Answer 1

Not neutrinos, neutrons. D-He3 fusion does not produce neutrons, which activate reactor materials. So, a reactor that used only this reaction would not produce radioactive waste. Preventing D-D fusion while you're at it is a complication, however. D-D does make neutrons. One way of avoiding this is to counterstream cold recirculating plasma beams of D and He3, but this has limits as to the gain achievable.

Answer 2

basically the amount of neutrinos that are created as a by product in a fusion reaction are far less with Helium 3. as such, the inside walls of the reaction chamber do not degraded as quickly making fusion energy more practical. though i am not sure, i remember reading something about this a year or two ago so can not be sure, it may as very well be that the amount of energy to create an sustain the reaction is less making for an actual net energy gain. or was it that the temperature needed was less, which is a kinda combination of the first two answers. well i hope you know the answer and were just asking to see if anyone else knew, if this is the case i would really be interested to know what the answer is. but if you don't know, i am at least sure it is along these lines.
