...Utah fusion experiment, researchers B. Stanley Pons and Martin Fleischmann ran a current through a palladium electrode immersed in heavy water. They announced on March 23 that the deuterium nuclei in the water fused together into helium, releasing energy...
Nonetheless, while the evidence is suggestive, there is still no clear understanding of what is going on. In their experiment, Pons and Fleischmann immersed electrodes of palladium and platinum in a bath of heavy water -- water whose ordinary hydrogen has been replaced with an isotope called deuterium. When they passed a current through the electrodes, the contraption produced heat. They concluded that deuterium ions had moved into the spaces between palladium atoms and fused together to form helium, giving off heat in the process...
...measured between 60% and 80% more heat energy coming out of the experiment than had gone in. But they had to try the experiment five times before it worked. They did not even attempt to detect any neutrons being given off. And Georgia Tech's effort, patched together with deuterium from a local chemical outfit and palladium ordered from a Chicago precious-metals dealer, had a serious flaw. The neutron counter that indicated fusion was apparently not working properly. Said team leader James Mahaffey to the Atlanta Constitution: "I have really been in agony. The announcement was impetuous. The problem...
...techniques to reproduce the incredible pressures and temperatures in the center of the sun, where fusion occurs freely. Scientists have used either powerful magnets to keep the hot hydrogen plasma--at about 200 million degrees Centigrade--from touching anything physical or huge lasers to heat a small pellet of deuterium to similar temperatures...
...Italian researchers forced deuterium gas to diffuse into scraps of titanium at high pressure and at several different temperatures, ranging from 73 degrees below zero Centigrade--the temperature of liquid nitrogen--to room temperature. All other experiments have used either heavy water or liquid deuterium...
