NASA new test confirms that the ‘Impossible’ EmDrive thruster really works — New Patent Is Now Public

Engineer Roger Shawyer’s controversial EmDrive thruster jets back into relevancy this week, as a team of researchers at NASA’s Eagleworks Laboratories recently completed yet another round of testing on the seemingly impossible tech. Though no official peer-reviewed lab paper has been published yet, and NASA institutes strict press release restrictions on the Eagleworks lab these days, engineer Paul March took to the NASA Spaceflight forum to explain the group’s findings. In essence, by utilizing an improved experimental procedure, the team managed to mitigate some of the errors from prior tests — yet still found signals of unexplained thrust.

Elon Musk and SpaceX have been busy posting mac diamonds on social media, there is a man working hard to revolutionize our space travels in the future. It is possible that Musk may end up sending humans to mars by the next decade but if the British scientist Roger Shawyer’s creation reaches reality, our Mars trip would be way cheaper or at least won’t be fuel dependent. Because even a single gram of fuel won’t be used in the EM drive invented by Shawyer.

The EM drive or microwave radiation thruster has been in question for not adhering to the basic laws of physics given by Sir Isaac Newton. Notably, the third, every action has an equal and opposite reaction. The EM drive works by making the electromagnetic waves reflect back and forth in a closed frustum-shaped cavity structure theoretically generating enough thrust to propel an entire spacecraft.

By pushing microwaves into a closed, truncated cone and back towards the small end of said cone, the drive creates the momentum and force necessary to propel a craft forward. Because the system is a reaction-less drive, it goes against humankind’s fundamental comprehension of physics, hence its controversial nature.

On the NASA spaceflight forums, March revealed as much as he could about the advancements that have been made with EmDrive and its relative technology. After apologizing for not having the ability to share pictures or the supporting data from a peer-reviewed lab paper, he starts by explaining (as straightforward as rocket science can get) that the Eagleworks lab successfully built and installed a 2nd generation magnetic damper which helps reduce stray magnetic fields in a vacuum chamber. The addition reduced magnetic fields by an order of magnitude inside the chamber, and also decreased Lorentz force interactions.

However, despite ruling out Lorentz forces almost entirely, March still reported a contamination caused by thermal expansion. Unfortunately, this reported contamination proves even worse in a vacuum (i.e. outer space) due in large part to its inherently high level of insulation. To combat this, March acknowledged the team is now developing an advanced analytics tool to assist in the separation of the contamination, as well as an integrated test which aims to alleviate thermally induced errors altogether.

The UK Intellectual Property Office has granted a new patent to Roger Shawyer

Shawyer has been working on the EM drive since 1999. He has bagged four patents in the field of work, the first one in 1993 for the basic concept of a cylindrical thruster with a shaped internal dielectric. Now, the UK Intellectual Property Office has granted him a new patent for the microwave radiation thruster. It is an improved design having a non-superconducting specially shaped plate on one end and a superconducting flat plate on the other.

The microwave radiation thruster houses a circularly polarized input antenna and a detector antenna with polarization opposite to the input antenna. A phase locked loop is created between the two antennas and is used to put a check on the input frequency of the waves.

This process minimizes the internal Doppler shift (the change in frequency or wavelength of a wave for an observer moving relative to its source) for the electromagnetic waves and increases the thrust ring acceleration.

“There’s millions of pounds at stake on this particular patent,” Shawyer told IB Times. He has been working with an unnamed UK aerospace company to create the second generation of the EM drive.

Just like the Robert Shawyer’s electromagnetic thruster, Guido Fetta created the Cannae drive based on the EM drive concept. The development of the Cannae drive has been promoted by his company Cannae LLC. Recently, Fetta has also managed to get his thruster tested in the space.
