From the article:

With a blast of X-rays compressing a capsule of hydrogen to conditions approaching those at the center of the Sun, scientists from Sandia National Laboratories reported today that they had achieved thermonuclear fusion, in essence detonating a tiny hydrogen bomb. Such controlled explosions would not be large enough to be dangerous and might offer an alternative way of generating electricity by harnessing fusion, the process that powers the Sun. Fusion combines hydrogen atoms into helium, producing bountiful energy as a byproduct. "It's the first observation of fusion for a pulsed power source," said Dr. Ramon J. Leeper, manager of the target physics department at Sandia, in Albuquerque, who presented the findings at a meeting of the American Physical Society here. Fusion power would be safer than fission, the current method used in nuclear power plants, because fusion does not produce long-lived radioactive waste.
