While not listed in the article, this is the design goal of the SPARC reactor.
Their plan is to use FLiBe (Google it) blanket to breed tritium. The Be acts as a neutron multiplier.
As for non D-T fusion, the next best candidate is D-He3. Unfortunately, the only large scale source of He3 is on the surface of the moon and it would have to be mined, on the moon, and sent back to Earth.
- dmix 5y agoA study on feasibility of lunar He3 mining https://ui.adsabs.harvard.edu/abs/2014cosp...40E1515K/abstract https://ui.adsabs.harvard.edu/abs/2014cosp...40E1515K/abstra... Not as bad as I expected but not yet feasible economic wise. Assuming the fusion part exists.
- snek_case 5y agoAccording to wikipedia: "Fusing two deuterium nuclei is the second easiest fusion reaction." "The optimum energy to initiate this reaction is 15 keV, only slightly higher than that for the D-T reaction." https://en.wikipedia.org/wiki/Fusion_power#Fuels https://en.wikipedia.org/wiki/Fusion_power#Fuels
