John H. Schnurer, director of physics engineering at Antioch College (located in Yellow Springs, Ohio) claims about a 5% reduction in gravity.
The experiment uses the Meissner effect. Schnurer chills a one-inch diameter superconducting disk, levitates the disk with electrified coils, and measures the force of gravity above this experi- mental arrangement. A small plastic sample is supported on a balance scale which contains no metal parts. The interpretation of the experimental results is that the plastic sample weighs less by about 5% when the experiment is "ON".
If the disk is not "in the Meissner state" or if the power is off, there is no detectable weight change in the plastic sample.
This experiment, together with the earlier reports of similar results by Eugene E. Podkletnov, a Russian materials scientist, has created consid- erable interest in various laboratories, including at NASA.
