Over the years, other people have been discharging electric arcs into heavy water with no ill effects, but nobody has attempted to form a plasmoid in heavy water yet. I think it is worth a try.

Nope, isn’t. You won’t get plasma. For plasma you need gas. For a DPF to function you need a pressure of about 10mbar. You can try to fuse deuterium (didn’t follow what for, but anyway), but only as a gas. That’ll give you some neutrons (and some energy), but that’s it. In fact D-D fusion is a standard experiment done with a DPF.

And forget about fusing tritium in a industrial style, as I mentioned in another thread.
