It was quite a lot, but very interesting indeed and I havn’t found the part about increased confinement time jet.
What I’m asking about is if the plasma in the light arcs between electrodes really stays there or if a big part of the gas escape. There are a lot of devices producing a light arc with plasma using a voltage between two electrodes. Light tubes, plasma lamps, and more.
The compression don’t have to be crazy hard for fusion, if you add heat. But the plasma have to stay in place, and long enough, if it going to work well. If the plasma hits the walls and other solids object it cools down and the reaktion dies.
