Recreating the Power of the Sun

It's a long way from Princeton, NJ, to the center of the sun but, in a sense, that's the journey Harold P. Furth set out to take a year ago when he accepted the position of director of the Princeton Plasma Physics Laboratory.1 The laboratory, along with others elsewhere in the United States and in Western Europe, the Soviet Union, Japan and China, is attempting to re create on earth many of the conditions that exist at the center of the sun, attempting to produce energy the way the sun does through nuclear fusion. Fusion is the basic mecha nism that causes the sun and the other stars to shine. The interior of the sun is 14 million degrees centigrade, and at such high temperatures, its nuclear particles fuse together with the release of tremendous energy.
