Former NASA Engineer Says Electric Fields Yield Thrust Without Fuel

THE LABORATORY, U.S.A. — A former NASA engineer claims his research team has found a previously unknown force capable of producing thrust without expelling propellant, according to a report published by Unknown Country, which cites a 2026 article in Popular Mechanics.

The engineer, Charles Buhler, is described as an electrostatics specialist who worked at NASA's Kennedy Space Center and co-founded Exodus Propulsion Technologies. He says his team's system uses asymmetrical electric fields and carefully arranged electrodes to produce directional thrust. The proposed mechanism is sometimes called the "Exodus Effect."

According to the report, the team claims that by 2023 its experiments produced enough upward force to counteract the weight of the test apparatus. The article stresses that this does not mean gravity has been canceled or manipulated; the claim is only that the force exceeded the device's weight.

The underlying idea is described in U.S. Patent No. 11,511,891, issued in November 2022 to Mr. Buhler and co-inventor Andrew Aurigema. The report notes that a patent is not independent scientific verification. At an Alternative Propulsion Engineering Conference in August 2025, Mr. Buhler reportedly offered a theoretical explanation drawing on quantum electrodynamics, and his team maintains that conventional propulsion cannot account for the effect.

Skeptical context is supplied at length. A truly reactionless drive would raise grave questions about conservation of momentum, and an electric system would still need an energy source. The report recalls the EmDrive, whose reported thrust was tested by researchers at Dresden University of Technology; their peer-reviewed 2021 study in CEAS Space Journal found no anomalous thrust.

The publicly available evidence reviewed by the report's author does not establish independent replication, peer-reviewed confirmation or a demonstration in space. Until others reproduce the results under controlled conditions, the piece concludes, the Exodus Effect remains an extraordinary claim rather than an established breakthrough.
