Edward G. Harris's 1999 peer-reviewed paper formally rebutted Torr and Li's claim that a superconductor generates a detectable gravitomagnetic/gravitoelectric field

Edward G. Harris, a physicist at the University of Tennessee, Knoxville, published "Comments on 'Gravitoelectric-Electric Coupling via Superconductivity' by Douglas G. Torr and Ning Li" in Foundations of Physics Letters (12: 201–208, 1999). Its abstract states plainly: "Torr and Li claim to have shown that experimentally detectable gravitomagnetic and gravitoelectric fields can be generated in a superconductor. We review their calculations and show that because of unrealistic assumptions the fields that they calculate are too large by many orders of magnitude." Harris's reference list identifies the specific target as Torr and Li's 1993 Foundations of Physics Letters paper, "Gravitoelectric-electric coupling via superconductivity," with their 1991 and 1992 papers cited as background — not the 1991 Physical Review D paper that the vault's earlier claim-note is titled after.

This matters to the vault's framing of how the Li–Torr claim exited the literature. That earlier note originally described the claim as having drifted out through silent non-replication rather than formal refutation — the same soft-closure pattern the vault has traced elsewhere (see claim-superconductor-antigravity-effects-never-independently-replicated). A named, peer-reviewed, formal rebuttal does exist; it targets the 1993 paper specifically, which narrows but does not overturn that framing for the 1991 paper itself.
