On December 8 in 1993, "Fusion tests jolt energy record" is the worldwide headline about today's historic experiments at Princeton's Tokamak fusion reactor. The reactor produces over 3 million watts of power. The new record stands less than a day; the following afternoon 5.6 million watts are produced (enough power for 1,500 U.S. homes). Unfortunately, the energy-producing reactions can only be sustained for very short periods of time. If perfected, fusion holds great promise as an energy source - it is nonpolluting, inexhaustible, and produces few, low-level radioactive by-products.
