This limitation has not stopped people from investigating the possibility, and the latest addition to the propellant-less club is an electrostatic design developed by a former NASA engineer. While the company behind the drive, Exodus Propulsion Technologies, says that the drive can achieve a thrust to counteract Earth’s gravity, such a claim still needs independent verification and a healthy dose of skepticism. In 2001, British Electrical Engineer Roger Shawyer first introduced the “impossible drive,” known as the EmDrive. This culminated in 2023, when this “New Force”-powered drive generated enough thrust to overcome Earth’s gravity. warp drives), claimed to measure thrust from the “impossible” drive in 2016.
