Sun in a Bottle

September 1, 2008
Fifty years ago scientists and futurists glowingly predicted a future in which cars would run on little fusion cells and the world would extract deuterium from the oceans for an inexhaustible supply of energy. Like all too many shining visions, fusion turned out to be a mirage. Award-winning science journalist Seife (Zero
) takes a long, hard look at nuclear fusion and the failure of one scheme after another to turn it into a sustainable energy source. Many readers will remember the 1989 “cold fusion” debacle, but Seife explains why tabletop fusion isn't all that difficult to achieve. The problem, as with all fusion devices except the hydrogen bomb, is to produce more energy than the fusion process consumes. The two most promising approaches today use plasma and lasers, but again, Seife reports, scientists have been repeatedly frustrated. The United States and several other industrial nations recently agreed optimistically to sink billions of dollars into a 30-year fusion power project. Seife's approachable book should interest everyone concerned about finding alternative energy sources.
