Defense Intelligence Reference Document The Role of Superconductors In Gravity Research

Defense Intelligence Agency · 16 pages · text from the file's own layer

This Defense Intelligence Reference Document from the Defense Intelligence Agency is dated 23 March 2010. It was produced under the Advanced Aerospace Weapon System Applications (AAWSA) Program and surveys the history of attempts to use superconductors to manipulate gravity in the laboratory. It reviews theoretical work by Li and Torr, Podkletnov's disputed gravity shielding experiments, NASA replication attempts and Tajmar's results. It concludes that no repeatable effect has been verified and that research in this area remains fraught with experimental difficulty.
