Advanced and emerging propulsion technologies, including warp-drives, field-effect, the Searl Effect, hypersonics and more.
NASA Breakthrough Propulsion Physics: Revisiting The Top Prospects
More than two decades ago, NASA’s Breakthrough Propulsion Physics (BPP) program sifted through “impossible” propulsion claims, narrowed them to the most credible test targets, and ran lean feasibility studies. This…
Fran De Aquino’s System-H: ELF Gravity Control at One Hertz
The last object most people picture when they hear “antigravity” is a cannonball—an iron sphere with the blunt medieval logic of weight and impact. But in Professor Fran De Aquino’s System-H, that heavy ball isn’t a…
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”…
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…
Roger Shawyer’s EmDrive: Engineering The “Impossible Drive”
The EmDrive was called “impossible” because it promised propulsion without propellant - but the longer the debate ran, the more impossibility shifted from theory to practice. The hard part wasn’t drawing a cone on a…
Reverse Engineering Ancient Vimanas: From Sanskrit to Schematic
Ancient Indian scriptures have long described Vimanas—flying machines that defy gravity, vanish into the skies, and harness the sun’s power. For centuries, these tales were viewed as mythology. But aerospace engineer…
Ion Drive Propulsion: Types, Development, and Future Prospects
Ion drives – more broadly, electric propulsion systems – mark a sharp break from the explosive, high-thrust chemical rockets that opened the Space Age. Instead of brief bursts of force, ion drives accelerate charged…
Stoyan Sarg and the SARG Effect: Reimagining Gravity and Propulsion
What if gravity wasn’t an immutable law to obey, but an engineering variable you could dial up, bend sideways, or almost switch off—enough to lift a ship without rockets, glide through the air in a cocoon of altered…
