Bussard’s method is highly promising and has created fusion. It is not a scam. It hasn’t produced a functioning fusion reactor yet, something it shares with every other fusion research project.
It may or may not be the way forward for fusion, but Govt funding often goes to sink projects at the behest of special interest groups, rather than to the best achievers. I can believe this guy’s been shut out.
I don’t believe he’s a con man nor is this a scam for funds, but the math and science is so technical, how can you separate the wheat from the chaff?.......
