Plasma/fusion energy research

A colleague asked me why I was no longer doing plasma/fusion research.  I could have answered that there was some original plasma/fusion work published in my book "Twelve Papers" just last year, in October 2011.  But the plasma/fusion work presented in that book was some of the oldest work in a volume that took many years to write. So my answer instead was that in the united states support for plasma physics and magnetic fusion energy has declined substantially since the early 1980s.  (It's true inertial confinement spending went up but some of that must be considered military research, not plasma/fusion energy.)
