Tajmar, Plesescu, Seifert and Marhold pursue their proposal that a rotating superconductor produces, besides its London moment, a large gravitomagnetic field that would explain an apparent mass increase of niobium Cooper pairs. A similar field follows from general relativity combined with the observed amount of dark energy. They built a facility to measure small acceleration and gravitomagnetic fields near a fast rotating, accelerating superconductor. Niobium measurements show first signs within a factor of 2 of their prediction, and possible error sources are reviewed. If this gravitomagnetic London moment exists, acceleration fields could be generated in the laboratory.
