1) World helium-3 reserves mean they can only be an irrelevant amount of total energy. Otherwise it's just D-D or D-p fusion with extra steps (and all the neutron problems involved).
2) The magnetic energy recovery can at best reach parity with the thermal, which makes it yet another solar freakin' roadways if not a theranos. They play sleight of hand with this in all their marketing materials which indicates they know it's a show stopper but do not want anyone paying attention to it.
The slick marketing, the sexy story, the massive hole in their story, and the startup posturing put them with every other scam startup that promises the world and then folds after an IPO with VCs disappearing with a the later investors' money.
In DD followed by D3He most of the energy is coming from D3He, especially if you let the tritium decay (admittedly that takes a while.)
The magnetic energy recovery scheme would allow the energy of compression to be recovered at high efficiency. If this worked, they could have a practical, energy producing system even with Q < 1. I believe they are aiming for Q = 0.2.
The idea that it "can at best reach parity with thermal" seems without any justification. Perhaps we could debug the source of your misunderstanding?
