Amazing No Fuel Engine – Is This Now The Answer To Deep Space Travel?

The engine that shouldn’t work keeps on causing confusion and excitement at the same time. As reported by Science Is Wicked! the Electromagnetic Propulsion drive in theory has the ability to reach Mars in around 70 days instead of the years originally estimated by using conventional rockets. Further testing has been completed by NASA and the results are that the EM drive continues to develop thrust. It’s still early days but this invention is defying Science as it shouldn’t work.

The drive was invented by Inventor Roger Shawyer, from England and if the testing can be scaled up and fully proven there is the chance of being able to reach the moon in 4 hours!

What do NASA have to say about the invention, check out the post for all the details:


Paul Mach, one of the principal investigators at the Eagleworks Lab, has provided the first public update about their tests on the EM Drive in months, and has admitted that the team has upgraded their experimental protocol and mitigated some of the errors that people were concerned about in prior tests.

“And yet the anomalous thrust signals remain…” Mach wrote on the NASASpaceFlight forums.

His comment was in response to an unpublished paper, which claimed that the propulsion seen in earlier trials of the EM Drive were a result of Lorentz force – which means the force generated by interactions between the EM Drive and the Earth’s magnetic field.

Mach explains that he can’t comment on this work in detail or provide any photos, as his lab is in the process of getting a peer-reviewed paper published, but that he can shed some light on the issue.

“I will tell you that we first built and installed a 2nd generation, closed face magnetic damper that reduced the stray magnetic fields in the vacuum chamber by at least an order of magnitude and any Lorentz force interactions it could produce,” wrote Mach.

He also admits that there are still traces of contamination caused by thermal expansion in the system, and the team is now developing an advanced analytics tool to try to work out where this is coming from.

The Em Drive stands for electromagnetic propulsion drive, and the reason it’s so controversial is that it defies one of the fundamental concepts of physics – the conservation of momentum, which states that for something to be propelled forward (like a spacecraft), some kind of propellant (like fuel) needs to be pushed out in the opposite direction.

And so far a range of scientists, including the NASA team, have shown that the engine “is producing a force that is not attributable to any classical electromagnetic phenomenon,” as the Eagleworks researchers wrote in an unpublished paper last year. In other words, it seems to work, but they can’t explain why.
