Their approach is based on a US Naval research concept called "Linus" and old research done by General Atomics. They feel we now have the high speed digital processing capable of pulling off the feat, where decades ago the technology was not available. I think we can hold off on the "vaporware" and "scam" tags for a little bit on this one; everyone is aware of the horrible track record for turning fusion concepts into reality, and they don't claim to be the first with the idea or that there are not substantial challenges in the way. If nothing else it is a fascinating concept.
