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
[[entity-douglas-torr|Torr]] and [[entity-ning-li|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
[[claim-ning-li-1991-gravitomagnetic-superconductor-antigravity-proposal|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.
