Discovering a machine that might one way or the other produce thrust with out releasing propellant can be a game-changer for human house journey. There’s only one downside—such a tool would defy the legal guidelines of physics.

This limitation has not stopped folks from investigating the chance, and the newest addition to the propellant-less membership is an electrostatic design developed by a former NASA engineer.

Whereas the corporate behind the drive, Exodus Propulsion Applied sciences, says that the drive can obtain a thrust to counteract Earth’s gravity, such a declare nonetheless wants unbiased verification and a wholesome dose of skepticism.
In 2001, British Electrical Engineer Roger Shawyer first launched the “not possible drive,” often called the EmDrive. It was referred to as “not possible” as a result of its creator purported that the drive was reactionless, which means no propellant required—in different phrases, it defied the identified legal guidelines of physics (particularly, the conservation of momentum).
As with something that seems to thumb its nostril at Newton and Einstein, scientists raised various eyebrows, and twenty years of testing finally boiled all the way down to an inevitable (and considerably predictable) conclusion in 2021: the EmDrive was bunk. However that’s the character of the scientific methodology—take a seemingly not possible thought, put it via rigorous testing, and hopefully get to an unassailable conclusion (or new discoveries that lead in different instructions).
The not-based-in-physics dream of a propellant-less machine, nonetheless, didn’t die with the EmDrive. As an alternative, a brand new challenger approaches, and this one has a former NASA scientist backing it up.
Whereas at NASA, Charles Buhler helped set up the Electrostatics and Floor Physics Laboratory at Kennedy Area Middle in Florida—a very essential lab that principally ensures rockets don’t explode. Now, as co-founder of the house firm Exodus Propulsion Applied sciences, Buhler instructed the web site The Debrief that they’ve created a drive powered by a “New Pressure” outdoors our present identified legal guidelines of physics, giving the propellant-less drive sufficient increase to beat gravity.
“A very powerful message to convey to the general public is {that a} main discovery occurred,” Buhler instructed The Debrief. “This discovery of a New Pressure is key in that electrical fields alone can generate a sustainable pressure onto an object and permit center-of-mass translation of mentioned object with out expelling mass.”
Buhler confused that this work is unaffiliated with NASA, and that he not too long ago offered his findings on the Different Propulsion Vitality Convention (APEC), which is a membership of engineers and fanatics keen to seek out methods to beat the constraints of gravity and physics—and never at all times with probably the most scientifically sound strategies.
In an interview with APEC’s co-founder Tim Ventura, Buhler defined how his background in electrostatics led to the invention. He says his staff—made up of individuals from NASA, Blue Origin, and the Air Pressure—investigated propellant-less drives for many years earlier than arriving at electrostatics. For years, their units produced negligible thrust, however noticed will increase with every new iteration. This culminated in 2023, when this “New Pressure”-powered drive generated sufficient thrust to beat Earth’s gravity.
“Primarily, what we’ve found is that methods that include an asymmetry in both electrostatic strain or some type of electrostatic divergent subject may give a system of a middle of mass a non-zero pressure part,” Buhler instructed The Debrief. “So, what that principally means is that there’s some underlying physics that may basically place pressure on an object ought to these two constraints be met.”
Clearly Buhler’s claims are fairly “woah, if true,” however the historical past of propellant-less drives is crammed with seemingly constructive outcomes which are finally dashed upon the rocks of scientific actuality. For the EmDrive, hopes for the system skyrocketed after NASA’s Eagleworks staff, which is devoted to investigating new types of propulsion (i.e. warp drives), claimed to measure thrust from the “not possible” drive in 2016. Nevertheless, subsequent research—together with an exhaustive (no pun supposed) one on the Dresden College of Expertise—discovered zero thrust.
Earlier than any different propulsion fanatics ought to begin popping corks, rigorous, third-party analysis should confirm the outcomes time and again. Whereas it’s not not possible that Buhler et. al stumbled throughout some unknown quirk of physics, it’s an especially unlikely end result.
For now, let’s name it an “unbelievable engine.”
