I thought the end game was aneutronic fusion using lithium and deuterium anyway creating only charged particles instead of high energy neutrons that are dangerous and damaging to the reactor. If nuclear fusion ever wants to be commercially viable, it must not depend on tritium.

- DennisP 4y agoHelion is working on a deuterium/helium-3 reactor, which if it works will produce only 6% of its energy as neutron radiation. YCombinator was an investor. They've run six reactors and are building a seventh now for a net power attempt in 2024. There are also at least four companies working on proton-boron fusion, though all but one are very small. (TAE is the exception.)
