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.
Sandy Kidd’s Gyroscopic Propulsion Device
Some inventions begin as equations. Sandy Kidd’s began as a shove—an aircraft gyroscope pushing back so hard it felt, for an instant, like the machine had a will of its own. The physics is ordinary: angular momentum and…
The Polyakov Vortex Drive: a Liquid Gyroscope for “Reactionless” Propulsion
In the Russian alternative-propulsion world, “reactionless drive” doesn’t always mean hidden rockets or exotic fields. Sometimes it means something much stranger—and much more mechanical: a sealed device that tries to…
Yubileiny: Russia’s Launch of an Experimental “Reactionless” Drive
In 2009, Russian headlines carried an unexpected story: the educational satellite Yubileiny—launched the year before to commemorate the 50th anniversary of Sputnik 1—was reportedly testing an experimental “reactionless”…
Gennady Shipov’s Teleparallel Torsion and the 4-D Gyroscope
For more than a century, physicists have stretched Newton’s laws with relativity and quantum mechanics. A fourth extension, rooted in the geometry of “torsion” and championed by Russian theorist Gennady Shipov, goes…
The First Step to the Stars: James F. Woodward’s “MEGA Drive” and Mach-Effect Propulsion
At Cal State Fullerton, a revolutionary propulsion program aims at the unthinkable: thrust without propellant, a steady shove drawn from the physics of inertia. For over thirty years, James F. Woodward led that effort,…
MEGA Drive Propulsion Experiments
Dr. James Woodward demonstrates experimental testing with the Mach Effect Gravity Assist (MEGA) drive using a 150g device and an 885g support structure. Woodward's team used a Logitech Trio to record device motion, a…
Mach’s Principle & The MEGA Drive
Dr. James F. Woodward discusses Mach Effect Propulsion & the Mach Effect Gravity Assist (MEGA) drive, an experimental propulsion system designed leverage transient mass fluctuations as the basis for a new form of space…
Mach Effect Propulsion
Dr. James Woodward discusses Mach Effect Propulsion, which postulates that energy-storing ions experience transient mass fluctuations when accelerated. Unlike conventional technologies, drives based on the Mach Effect…
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,…
