Eugene Podkletnov is a Russian scientist working in Tampere, Finland. In a 1992 experiment with a rotating high-Tc superconducting disk, Podkletnov noticed that the tobacco smoke from a pipe rose slightly when floating above the device. After several measurements, he reported that the gravitational force directly above the disk was about 0.3% less than normal. He concluded that the superconducting disk was altering the earth's gravitational force above it.
Since this initial experiment, Podkletnov has supposedly been improving the technique, so that as much as a 2% decrease in the gravitational force has been reported.
In addition, Podkletnov, in collaboration with Italian physicist Giovanni Modanese, has built another device that reportedly generates a "repulsive" gravity beam that is several orders of magnitude stronger than the aforementioned experiments. This beam is supposedly coherent and can act at great distances, and has been observed to cause motion in a pendulum that was 1500 meters away across several buildings. At the backside of this device, it was observed by Podkletnov that it emits radiation dangerous to biological tissues.
These experiments have caught the attention of several American organizations (most notably NASA and Boeing), but they have kept a low profile about their research, lest they be criticized by the mainstream scientific community.
So far, all independent attempts to reproduce Podkletnov's original experiment have yielded either negative or inconclusive results. This may be due to the extreme difficulty of reproducing the type and size of the superconducting disk used by Podkletnov.
Information on the exact whereabouts of Podkletnov or the progress of his work remains very scarce, and may lead one to question the validity of his findings.
