For years, the scientific community largely shunned the work of British scientist Roger Shawyer, whose revolutionary space propulsion system, the EmDrive, seemingly defies the laws of physics in its ability to create thrust without the need for propellant. In response to growing interest in Shawyer’s work, whose EmDrive was successfully replicated by other scientists around the world, NASA finally took an interest and built their own version, culminating in a statement released last week in which NASA confirmed the validity of Shawyer’s invention.
Shawyer’s EmDrive uses electricity to excite microwaves that in turn generates thrust. Instead of propellant, microwaves “bouncing around in a closed container” allows the drive to push against invisible fields of particles and anti-particles swirling around in thin air. Amazingly, this process is suspected of breaking the laws of the conservation of momentum that states “momentum is neither created nor destroyed, but only changed through the action of forces as described by Newton’s laws of motion.”
Once perfected, the technology behind Shawyer’s invention ensures the possibility of exploring the farthest reaches of our cosmos. The EmDrive’s ability to harness solar power to generate the electricity needed to direct microwaves for thrust will allow satellites and space stations to travel farther and faster into deep space than ever before. Instead of months, astronauts could potentially reach Mars in weeks.
[The EmDrive] has demonstrated a remarkable new space propulsion technology. [It] has successfully tested both an experimental thruster and a demonstrator engine which use patented microwave technology to convert electrical energy directly into thrust. No propellant is used in the conversion process. Thrust is produced by the amplification of the radiation pressure of an electromagnetic wave propagated through a resonant waveguide assembly. – Statment released by Shawyer’s company, SPR Ltd.
