But, even less is being spent on that than on other aneutronic designs, which themselves are on shoestring budgets. Theoretical reasons make it seem like an unpromising avenue.
Confinement approaches aren't inherently neutronic or aneutronic. What matters is the temperature, desnity, and confinement time (lawson criterion). Get it sufficiently high then DT becomes a breeze. Get it a factor of 500 higher and pB11 is on the table.
No one serious talks about aneutronic fusion because we need to walk 1 mph before we sprint at 500 mph. We'll seriously discuss aneutronic fusion in 200 years when it's relevant.
