Straight from fusion to electricity without a steam turbine with helium to harvest? I've seen it said here on HN that the amount of helium out of a deuterium/tritium is so small it is negligible. From article: "My question is: Would that setup produce a continuous fusion for some period with positive net energy generation? Here is my argument why I think it would: Since Boron is solid at room temperature, it's density is high, so I think the fusion rate per nucleon would be quite high. As far as I know 100keV is the energy needed for Hydrogen-1 and Boron-11 to fuse, while the resultant three He-4 nuclei should have about 8MeV of energy. So indeed if all accelerated protons fuse then the energy produced should be quite higher than the input. The problem that immediately comes to mind is that as the container starts to rapidly heat up as a result of the reactions the Boron inside would no longer be solid and may even start to leak through the opening. But before that happens, would there be at least a brief period where an efficient fusion can be sustained?"
