Is there any reason to assume that all types of aneutronic fusion are equally difficult to achieve? Extrapolating from other sorts of fusion I'd assume that D-He3 fusion would take much less activation energy than other sorts.
- DennisP 11y agoD-T is the easiest, D-D the second easiest and produces He3. So there's really no reason to mine He3 unless you happen to be orbiting a gas giant with lots of it handy. Helion, a fusion startup funded by YCombinator, is working on a D-D/D-He3 reactor, breeding their He3. They say only 6% of the reactor's energy output would be neutron radiation.
