Is this real? Or has somebody debunked this? It sounds a bit sketchy with the recent woo-woo science scams, and with the CEO Richard Dinan not having any degree or even finishing high school.

Fundamentally it might be possible to have a non sustainable fusion reaction that requires more energy in than out, but that produces great impulse. But I haven't found anything that explains how it's done. And then the question becomes how they supply the power needed to do fusion and direct the output into one direction.
