...University's Program on Peace Studies and author of The Politics of Nuclear Proliferation: "No one has yet bought himself a big firecracker and been able to let it go at that." In fact, India may now even be tempted to expend the resources to develop a costly hydrogen bomb...
Giant airships vanished from the skies after the hydrogen-filled Hindenburg exploded and burned in 1937. But airship enthusiasts, buoyed by little more than hope, have remained at their drawing boards, designing huge lighter-than-air dirigibles that they believe could still compete effectively against other forms of transportation...
Fast Neutrons. Unlike the more familiar process of fission (in which energy is released by the breakup of atomic nuclei), fusion involves the combining (or fusing) of two nuclei of hydrogen. The reaction releases energy-primarily in the form of high-velocity neutrons-that scientists hope some day can be harnessed to generate electricity...
...controlled fusion can occur only under conditions of very high temperature and density that researchers have tried for years to produce by using powerful magnetic fields to squeeze or confine isotopes of hydrogen called deuterium and tritium. But even the best of these "magnetic bottles" -which require tremendous amounts of energy to operate-have so far been unable to provide the necessary temperature and density for more than a tiny fraction of a second...
...more efficient tool for creating fusion: the laser. By heating a tiny pellet of deuterium or tritium with a powerful pulse of laser light, they cause the explosive evaporation of the pellet's surface. As the material sprays off, the rest of the pellet implodes. The hydrogen nuclei are thus forced together. As early as 1968, a team of Soviet researchers under Physicist Nikolai Basov, a Nobel laureate, reported that they had used lasers to ignite a brief but clearly detectable fusion reaction. Since then, their experiments have been repeated-and improved upon-in a number of countries, including...
