MIT, Columbia begin new energy experiment

Half-ton levitating ring is key to work

MIT and Columbia University students and researchers have begun operation of a novel experiment that confines high-temperature ionized gas, called plasma, using the strong magnetic fields from a half-ton superconducting ring inside a huge vessel reminiscent of a spaceship. The experiment, the first of its kind, will test whether nature's way of confining high-temperature gas might lead to a new source of energy for the world.
