Compact Fusion

"The compact fusion concept (which has been around for several decades) is that instead of having a plasma field controlled by a vast amount of engineering to keep it under control, the plasma and magnetic field which keeps it under control are self regulating in a sort of positive dynamic - the magnetic field feeding off the plasma for energy, automatically getting stronger where the plasma expands or bulges. So, you just have a plasma field in a box big enough to hold it, without the need for any major external plumbing once its up and running." -PhilipD
