I mean maybe, I don't know. You're likely to crush whoever is in the vehicle trying to go that fast. Humans can only handle very low g-acceleration.
Thinking about it, a fusion rocket makes sense. The difficulty with building a fusion reactor is containing the plasma, but with a rocket you want the plasma to escape. It sounds much easier.
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.
