Lerner is highly confident that a high probability of p+B11 fusion ignition can be achieved with the decaborane alone. After exploring various options for some kind of supplemental energy boost …… heavy fissionable atoms, helium 3, deutrium, and the blacklight reaction …… none of them seem very likely candidates. A workable one, if found, still probably would not improve the FF reactor’s operation that much. About all it might do is perhaps reduce the electric power requirement for heating the plasma, but that’s about it. I still find it fun exploring such improbable options, even if many times they are not practical.
