Ceramics Engineer / Gravity-Modification Researcher
Genuine engineering credentials and peer-reviewed publications, but the central gravity-shielding claim has resisted independent replication for three decades. His historical influence is undeniable - Ning Li's career and significant NASA / DARPA / Boeing money flowed from his original 1992 report - but the underlying physics remains unconfirmed.
Tampere gravity-shielding result
Reported a 0.05-2% weight reduction above a rotating YBCO superconductor disc in papers published in 1992 and 1996. The result, if real, would represent the first laboratory demonstration of gravity modification.
NASA Marshall replication (with Koczor)
Tampere claim drew sustained NASA Marshall investigation under Ron Koczor in the late 1990s and early 2000s; the formal replication did not produce a clear positive result but the program kept the topic on NASA's table for years.
Impulse-beam experiments
Continued post-Tampere work claiming pulse-discharges through superconductors produce focused gravitational-impulse beams. Limited replication attempts.
A possibility of gravitational force shielding by bulk YBa2Cu3O7-x superconductor
1992 • Physica CWeak gravitation shielding properties of composite bulk YBa2Cu3O7-x superconductor below 70 K under e.m. field
1996Initial report of weight-reduction effect above rotating YBCO superconductor.
Expanded methodology and results in second peer-reviewed publication.
Reportedly leaves Tampere University of Technology amid controversy over the gravity claims.
NASA's multi-year replication attempt concludes without a clear positive result.
