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.
The 3M Invisible Wall: The Legend of an Electrostatic Force Field
In the late summer of 1980, in a South Carolina tape plant, static electricity appears to have stopped behaving like a nuisance and started acting like a force field. A broad polypropylene web rose from a jumbo roll,…
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…
Dogfighting In Space: Can Exodus Electrify Delta-V for the Space Force?
In a contested orbital environment, survivability is starting to look less like armor and more like agility. Debris clouds can be manufactured with a missile test, “inspector” satellites can drift close enough to make…
Charles Buhler and Exodus Technologies on Propellantless Propulsion
What if spacecraft could maneuver endlessly without ever carrying fuel? In a small Florida lab, physicist Charles Buhler and Exodus Technologies are betting on a radical idea: propellantless propulsion driven by…
Exodus Propellantless Propulsion Physics
NASA physicist Dr. Charles Buhler explores the physics behind the breakthrough propellantless propulsion device developed by Exodus Propulsion Technology. His team made international headlines in 2024 for producing 1g…
Exodus Propellantless Propulsion Lab Walkthrough
NASA physicist Dr. Charles Buhler does an impromptu electrostatics lab walkthrough and describes the evolution of Exodus propellantless propulsion drives at their electrostatics lab in Merritt Island, Florida. Their…
