Reactionless and inertial drives under the microscope: Mach-effect thrusters, gyroscopic devices, and momentum-exchange concepts. Learn the theory, the rigs, and the data quality standards. Our goal is reproducible measurements that separate genuine thrust from vibration or test-stand bias.

Inertial Propulsion and the Pulsed Inertial Engine (PIE)

Bryan St. Clair discusses advances in Pulsed Inertial Engine Technology (PIEtech), including a new “PIE Mini” that is a functional miniature demonstration model. He has just posted some videos on YouTube and bitchute of…


Pulsed Inertial Engine Technology

Bryan St. Clair of St. Clair Tech R&D discusses PIETech (Pulsed Inertial Engine Technology), a novel propulsion system inspired by Roy Thornson's Ezekiel engine. PIETech, described as a "Model T" of inertial propulsion,…
