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…
