"It’s a low-energy reaction, so they’re going to have to figure out how to speed it up if they’re going to make power."

Yes and no. The reaction itself is NOT low energy (24+MEV/nucleon formed--for the PD/D2 case). Getting more nucleons to react CONTROLLABLY is what is needed, and the tech is just getting to that point. But for the very small reactors used, the "energy density" is greater than that for a fission reactor.

Seems like if it was producing that much energy it there wouldn’t have been this much disagreement of whether or not it’s actually producing any energy.
