There is also fusion with low neutron flux [1] (among the others: Helium 3) but it is even more difficult to achieve. I'm not confident that any of us will ever see a commercial fusion reactor. I'm afraid that all we can do to harness fusion energy directly is by the means of solar panels. [1] https://en.wikipedia.org/wiki/Aneutronic_fusion https://en.wikipedia.org/wiki/Aneutronic_fusion
