This documents reports on an ARPA-E sponsored JASON assessment of the “Prospects for Low Cost Fusion Development.” Specifically, the question is whether magneto-inertial fusion (MIF) is a promising approach toward achieving controlled thermonuclear fusion at dramatically lower costs than other approaches.


Table 5 gives an overview of goal parameters and in some cases achieved parameters for the different fusion approaches.

Is from last November. I think it was posted here before.
I don't like it much. It seems overly pessimistic and gets some technical details wrong.
E.g. the assumption that a machine capable of achieving scientific break even would cost several hundred million is unfounded. Helion is building a full scale prototype right now with a budget of <40 million.
ZAP (the sheared flow stabilized Z- Pinch) would probably not need more than that.
He did not get the details about Helion's concept right either and he assumes that He3 would be hard to come by.
