摘要

Some say that a dollar spent on nuclear fusion is a dollar wasted. And many, many dollars have been spent on it, as physicists try to duplicate, in a controlled setting, the process by which the sun shines. Since 1951, America alone has devoted more than $17 billion (see chart on next page) to working out how to fuse atomic nuclei so as to generate an inexhaustible supply of clean, safe power. The claim that this money is wholly wasted may not be entirely fair, though. Fusion science has made a big return on this investment in the form of a new universal constant. This constant is the number 30, a figure that has for the past half-century or so been cited almost religiously by researchers as the number of years that it will take before fusion power becomes a commercial reality.
