Back in 1983 I demonstrated that turbulence could improve plasma confinement in an internal ring machine. (Plasma Physics, vol. 25, pg 901, 1983 and other publications, see http://www.robert-w-jones.com/, publications)
At that time I couldn't get funding to continue the work but now MIT (and others) are pursuing the "turbulent pinch" (PSFC/JA-10-22, Boxer, et al, Dec. 2010 and Nature Physics, 6, pg 207, 2010). Better late than never. We still have an energy problem.
