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.

One of the standard ways of producing a cavitation bubble is by electric discharge.

The electric discharge vaporizes the water (also true for heavy water) to form a cavitation bubble; the more powerful the discharge, the more gas volume that the cavitation bubble contains. It is in this gas bubble composed of deuterium and oxygen, where the FF plasmoid will form.

In other words, the electric discharge makes its own gas deuterium gas pocket.

I could show you pictures of how this looks if you need them. There is a shock wave formed during the collapse of the cavitation bubble of over 10 Gpa. By comparison, a diamond anvil can only produce 1 to 2 Gpa maximum pressure force.

On the down side, this shock wave might damage the electrodes and some engineering might be needed to avoid this damage. On the plus side, this very high pressure might increase the D-D fusion level.

Some people think that fusion occurs in a water cavitation bubble collapse without a plasmoid being induced. Maybe; it does produce some neutrons.
