Yep, big magnets cost big bucks (but boy are the images impressive!). I almost voted 3, but went with 4. We’re the only transparent horse in the race, have the lowest ongoing and incremental budgets, and if successful, will produce the lowest priced machines on the market. No reason to change that now, that I can see.
Something to keep in mind is that the programs getting the big bucks for as yet unproven technologies (both fusion and fission) have in-person salespeople and very likely have a sales department budget at least the size of our total operating budget.
