They are getting plasma pressures at levels similar to tokamaks and stellerators, which is pretty impressive, while using a fraction of the magnetic field. If you didn't know, 1 keV temperature is a little over 10 million K, and a density of 10^20 m^-3 is close to vacuum, but because of the high temperature the pressure is fairly significant, on the order of one atmosphere. It's refreshing that they don't exaggerate their progress (they admit that tokamaks are more advanced as of yet). But if they were trying to offer a cheaper alternative to tokamaks, they have a way to go. At 23m long, their FRC is not small. If they need to scale it up considerably to reach reactor levels, well, it's going to be an expensive project like ITER is.
If the FRC turns out to be the way forward, most our research into tokamaks hasn't been wasted. There's a lot of overlap in the theory and the technologies used. Neutral beams are also used in tokamaks, for heating and diagnostics, and are also being used to provide torque to the plasma, which can stabilize the plasma in various ways which can be understood in turbulence theory. The NIMROD code is also used in tokamaks, as is the technique of lithium wall conditioning. I suppose the point is, a lot of slashdotters will condemn the work of government research but this research wouldn't have been possible without decades of groundwork backed by government funded grants.
