  Right. where’s the actual content, the wording not treating us like idiots?

    There is no current actual improvement other than the possibilities. By cooling the plasma edge and using clean wall materials, they broke a theoretical density barrier that could potentially bring steady-state fusion closer to reality.

    That’s all it is. We’re no closer to steady fusion, but now we know we can push past the Greenwald limit.

      Thanks. Seems like a positive step

  Plasma is made from basicly over charging a gas with electrons the gas getting all pissy about having those electrons and starts dumping them. something do with elements wanting stability. In that process you get alot of heat out put. Now f you make it more dense I would conclude simply, you now have more ionized atoms in the plasma stream, meaning your plasma will be hotter if the stream will be the same size or if the plasma stream is shrunk but has the same number of ionized gas atoms, you have the same heat out put but in a smaller stream.

    You’re having a space characters infestation, you should do something about that.

  While a plasma is far from an ideal gas:

  pV=nRT

  p is the pressure, T the temperature, when you increase the pressure while keeping everything else the same, you increase the temperature aswell. The density here is the colloquial term for pressure.
