The Biefeld-Brown effect, high-voltage lifters, and beyond. We cover physics, ion wind questions, vacuum tests, materials, and power electronics—plus replication efforts and aerospace relevance. Start here for a balanced view of evidence, claims, and routes to rigorous measurement.
Electrostatic Levitation in Air: Al Baur’s Untethered Ion-Wind Levitators
The first shock of Al Baur’s presentation is visual, not theoretical. A small object hangs in space beneath a charged track with no string, no rod, no visible support, and then begins to move as if it has found a groove…
Viktor Grebennikov’s Beetle Wing Levitation
Viktor Grebennikov was a Siberian entomologist with a gift for seeing grandeur in the smallest forms of life who claimed that the hidden underside of an beetle wing revealed a microscopic architecture so extraordinary…
Biefeld-Brown Effect Explained? Tom Valone, Electrogravitics, and Jefimenko’s Causal Fields
In the breakthrough-propulsion world, high voltage gets all the glamour—big capacitors, big arcs, big claims. Tom Valone’s most interesting move is almost the opposite: the action is argued to live in the edge, in the…
Electrogravitics Engineering: Tom Valone’s Experimental Playbook for High-Voltage Propulsion
Electrogravitics is one of those rare engineering rabbit holes where the hardware looks almost too simple—plates, dielectrics, sharp edges, high voltage—yet the meaning people attach to it keeps multiplying. Put the…
The Hunt for Zero Point: 25 Years Later
In January 2001, aerospace journalist Nick Cook—former aviation editor at Jane’s Defence Weekly—published a book on secret government projects that left an indelible mark on aerospace culture. Over time, it also became…
Beyond The Hunt For Zero Point
Twenty years ago, the former aviation editor of Jane’s Defence Weekly stunned the world with “The Hunt for Zero Point”, which offered insights into the secret Nazi weapons programs of World War II and how those…
Electrogravitic & Electrokinetic Propulsion Overview
Dr. Tom Valone discusses the origins of electrogravitics and electrokinetics, which can be traced to T. Townsend Brown’s first article “How I Control Gravity” (Science and Invention, 1929). Brown reported that the…
Reactionless Electric Field Thrusters
Jeremiah Popp presents a detailed overview of various "Gradient Field Drives" which are claimed to produce reactionless propulsion by means of electric field gradients, and examines designs by Thomas Townsend Brown,…
Subquantum Kinetics & Pais Navy Gravity Patents
Dr. Paul Laviolette presents his electrogravity theory of Subquantum Kinetics as a replacement for conventional physics, arguing that it better explains anti-gravity phenomena. He detailed his model, emphasizing its…
