As a professional, theoretical physicist (M.A., M.Sc., Ph.D.), having heard here Dr Eugene Podkletnov's explanation of the loss of weight of objects suspended over his spinning, superconducting ceramic discs, I can say with full confidence that he does not know what he is talking about. Or, to be more accurate, he is a low-temperature physicist who seems to have little understanding of fundamental, theoretical principles and particle physics (my research field) - a quite common occurrence amongst such experimentalists, in my experience, unfortunately. Whilst, according to Einstein-Cartan theory, spinning matter would generate a torsion component in the space-time connection and a repulsive, gravitational force in addition to the normal, attractive component, the speed of rotation is far too low for the angular momentum density to create even a 5% change of weight (the calculations are too long and technical to add here). So the effect is not due to generation of torsion in the space-time metric.
What is really happening has nothing to do with altering gravity. It is far simpler than that. A magnetic field is generated by the currents of electrically charged Cooper pairs circulating in the surface of the rotating, superconducting ceramic disc, expelled from its interior by the Meissner Effect. This field couples to the atomic nuclei in the suspended object. Their intrinsic magnetic momentum makes them behave as minute magnets with their own magnetic fields, and it is the mutual repulsion between their fields and the magnetic field of the currents of Cooper pairs that causes the levitation, making it appear to lose weight. It is merely a form of magneto-levitation that exploits the natural diamagnetism of objects.
That is all I wish to comment on the topic.
