Physicists at the U.S. Department of Energy`s (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered valuable information about how electrically charged gas known as `plasma` flows at the edge inside doughnut-shaped fusion devices called `tokamaks.` The findings mark an encouraging sign for the development of machines to produce fusion energy for generating electricity without creating long-term hazardous waste.
