AC Gravity LLC, Ning Li's successor company, reportedly took a $448,970 U.S. defense grant in 2001 and never published results

After the university phase of her 1991 gravitomagnetic-superconductor proposal, Ning Li's work moved into a private successor company, AC Gravity LLC. The company is reported to have received a U.S. Department of Defense grant of $448,970 in 2001 to continue the research; per the secondary account, "No results from this research were ever made public." The company is confirmed by a directly-read Alabama Secretary of State record to remain a registered, active business as of 2026, and a 2022 Freedom of Information Act request for the underlying grant paperwork was administratively closed without releasing any documents.

[unverified-quant — the $448,970 figure and the 2001 award date trace to a specific named primary document ("Annual Report on Cooperative Agreements and Other Transactions Entered into During FY2001 Under 10 USC 2371," p.66, agreement DAAH01-01-9-R001), corroborated by a second independent secondary transcription giving matching figures, but the document itself has not been independently read — it survives only as an unfetchable Wayback snapshot of a legacy .doc file. The "never published" characterisation likewise has no independent primary confirmation; it is an absence claim resting on Wikipedia, Huntsville Business Journal, and Freethink alike, and a DTIC search this session found neither confirmation nor disconfirmation.

The concrete detail — public money spent, nothing published, the corporate shell still legally alive — is what makes the case durable. It is the institutional half-life of an unreplicated claim: where a paper can quietly lapse, a funded entity leaves a paper trail that outlives the science and can be re-narrated later. This grant record is the factual seed that a 2026 U.S. "dead and missing scientists" conspiracy theory later drew on when it listed Li among its named cases — a funded-but-silent company reading, to a pattern-seeking eye, as concealment rather than a dead research line.

The grant is documented in a DoD report titled "Annual Report on Cooperative Agreements and Other Transactions Entered into During FY2001 Under 10 USC 2371" — meaning it was issued as an "Other Transaction," DARPA's own lighter-oversight funding class, invented in 1989 for work outside standard procurement or grant review. That mechanism, not shared subject matter, is what actually connects this case to Nestor Inc.'s DARPA/ONR-funded neural chip — a surface-similar but evidentially opposite case (real technology, unprofitable business, vs. real grant, silent record).
