Wouldn't you know it. Princeton's Plasma Fusion Lab is trying to hang on to funding.
"Physicists see solution to critical barrier to fusion" http://phys.org/news/2012-04-physicists-solution-critical-barrier-fusion.htm l "An in-depth analysis by scientists from the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) zeroed in on tiny, bubble-like islands that appear in the hot, charged gases-or plasmas-during experiments. These minute islands collect impurities that cool the plasma. And it is these islands, the scientists report in the April 20 issue of Physical Review Letters, that are at the root of a long-standing problem known as the "density limit" that can prevent fusion reactors from operating at maximum efficiency." -mark
