In 2020 Russian engineer Eugene Podkletnov showed a video in which a sample appeared to be affected above a fast-spinning disc, presenting it as evidence of local gravity modification. Unlike his famous 1990s experiments with superconductors, the disc was reportedly an ion-implanted gold layer on an aluminium base, working at room temperature.[1][2]
Earlier claims
Podkletnov, a ceramics engineer trained at the Mendeleev Institute in Moscow, earned a materials science doctorate at Tampere University of Technology in Finland. In a 1992 paper he reported that a rotating superconducting disc reduced the weight of objects above it by about 0.3 percent. A longer 1996 paper claiming about 2 percent was accepted by the Journal of Physics D but withdrawn after a leaked version caused a press sensation, which reportedly cost him his university post. In 2001 he and Italian physicist Giovanni Modanese described an "impulse gravity generator" using charged superconductors that they said produced a force beam.[3][4][5]
Industry interest

A BBC report said Boeing had funded a gravity research project called GRASP, which the company denied funding with its own money, and in 2002 Jane's Defence Weekly reported that Boeing, BAE Systems and Lockheed Martin had approached Podkletnov.[3]
The 2020 claim
Accounts of the 2020 video say Podkletnov had moved from superconductors to ordinary conductors and layered surfaces such as thin gold coatings. According to the testimony, he suggested that for space travel it would be better to use a similar principle with magnetic fields rotating at high speed.[1][2][6]
Assessment
No independent replication or peer-reviewed publication has confirmed any of Podkletnov's effects. A NASA-backed effort to replicate his work built apparatus but never completed a full test, and one analysis suggests the measured effects could be confounded by aerodynamic lift on the samples.[2][3]
