Why pressure should increase the superconducting transition temperature is not completely understood, but based on previous experiments Chu believes that making the appropriate chemical substitutions in the material might duplicate these high temperatures at normal pressure. This hypothesis has been put to the test by two survey projects which scan millions of stars in the Large Magellanic Cloud, the nearby satellite galaxy. Michel Spiro of Saclay in France also reported that his group had observed two microlensing candidate events. Some astronomers at the meeting believed that it was too early to attribute the star-image distortions to dark matter. This feature, the scientists believe, could lead to information storage at the molecular level if ever a way can be found to address individual clusters.
Power comes from a water bubble made to expand and contract by heating.
