Bussard's polywell may or may not work. It stands ahead of ITER because in principle, net power units need not require billions of dollars to develop. The science can be adequately proven (or disproven) with much smaller amounts of funding.
I think that research like this stands to benefit humanity considerably. I would award such efforts a
(with respects to BLoad's much harsher scoring system).
