It describes the work done by a researcher in Finland who claims to have found a way to partially negate the effects of gravity by using a spinning disk made of a superconducting ceramic. The disk is chilled to -334 F and zapped with an electromagnetic field that causes it to spin. A gadget that defies gravity would have profound business implications. Built into cars, trains, and planes it could drastically slash fuel consumption and open new vistas for designing vehicles with little concern for size and weight.
Many people are skeptical.
Others around the world are trying to duplicate the work now and the issue is expected to be settled in a few weeks. The issue I have linked to has several great articles about the subject and they are posted in full text with some graphics as well. This article featured a John H. Schnurer, director of physics engineering at Antioch College in Yellow Springs Ohio. Last fall he chilled a 1 inch diameter superconducting disk and established an electrical current through coils positioned around the disk. Above the disk was a plastic sample hanging from one end of a homemade balance containing no metal parts.
