I've begun background work, as part of my graduate physics studies at New Mexico State University, on an attempt to reproduce Eugene Podkletnov's 1992 superconductor gravity experiment as reported in Physica C. Dr. Podkletnov reported a small reduction in the weight of test samples suspended above his apparatus.
The project has been loaned the superconductor and other equipment used by the NASA Marshall Space Flight Center in their replication attempt. A NASA team and another laboratory led by George Hathaway attempted to replicate the experiment and reported null results. For the findings of George Hathaway's group see their Physica C article.
My background research has led to a lot of interesting physics. Check back here for periodic progress reports and references to other interesting research in the field.
