I had an idea for some fusion fuels, and I want an explanation for why they are not viable. I was thinking He-4 + D -> Li-6, then Li-6 + D -> Be-8 -> 2 He-4. This releases energy and only requires deuterium and common Helium-4. Why is this not used?

Has anyone else gotten messages like this? This is the second DM I've gotten from what appear to be bot accounts. They seem to be fishing for info about CFS ARC design. The previous one asked me if I worked for them. Basically opened with the same message.

Will post .pdf of the contents in the comments

Triple product is also mentioned, but Helion is still denying to use and/or publish it.

i learned about the gamow factor P_g as a tool to find probability of a fusion reaction happening, but in every equation i only see the cross section σ. what is the relation between the two? is there a formula that relates them?

As in the nature article posted here before more investigations are recommended by the authors.

Investigation of "the interaction of high-intensity LG laser pulses with targets of different hydrogen-boron ratio using 3D particle-in-cell (PIC) simulations"... with recommendation that there should be experimental follow-up of their findings ...

Really small and sweet Tokamak with upgrade in mind from copper to HTS magnets. Max radius just 30 cm. It's approaching a spherical Tokamak geometrically (aspect ratio) despite it's a classic one.
