If you are a lover of space and everything that happens in it, especially the projects, research, and advances that are being carried out in this enormous technical field, surely on some occasion you have heard of that peculiar engine EmDrive, a mechanism so strange that neither one's own NASA, at the time, managed to reveal why it worked or how it was possible to do so.
Going into a little more detail, especially if you don't remember too well why that engine has become so famous, tell you what it was devised by British engineer Roger Shawyer in 2006. The revolutionary idea that it presented was that, to function, it did not need to use any type of conventional fuel, moreover, because it did not have any type of moving part in its design since, to generate momentum All that was needed was a transformer capable of converting electricity into microwaves that were launched into a cone-shaped chamber capable of generating impulse.
Finally Unveiled Why the EmDrive Engine Seems to Work
As expected, many were the engineers who were willing to try to test this theory and all came to the same conclusion, the engine, despite the fact that literally contradicted Newton's law of conservation of motionIt did produce a minimum of impulse, which was insufficient to escape the force of our planet's gravity but which, in space, could be the solution to all human problems.
Curiously, despite the fact that there were many centers that investigated the way the engine works, all of them confirming that the small impulse existed, none, not even the creator of the motor itself, were able to explain the physical principles that drove it. Perhaps, at this point, the most popular research was carried out by NASA at the end of 2016 where it was concluded that, although the EmDrive offered a small push, they did not know how it was produced or why.
Despite the resources invested, NASA was not able to reveal why the EmDrive seemed to work properly
As a detail, tell you that it was precisely NASA that invested resources in the study of an engine like the EmDrive, not in vain extraordinary measures were adopted aimed at detect and isolate any possible phenomenon that could distort the measurements or that, likewise, it had the property of causing an impulse that was due to any type of undesired factor or effect. We must bear in mind that, in this sense, all precautions were little, especially if we take into account that the impulse caused by the EmDrive is very small.
After carrying out numerous tests trying to isolate the EmDrive from any type of interaction with other objects present in its environment or possible forces, even analyzing magnetic fields, changes in motor temperature, convection thermal currents, static electricity, vibrations , vaporization of gases in the chamber ... they did not discover anything with which to argue why the hypothetical impossible motor worked. Unfortunately and as we now know, they forgot that the Earth generates its own magnetic field.
A latest study carried out by researchers at the University of Dresden establishes that the EmDrive works due to the Earth's magnetic field
As revealed by a group of researchers from the Dresden University, during their tests they decided do not use any of the EmDrive prototypes that travel from lab to lab for testing, but literally they built their own making use of the latest manufacturing technologies available. Thanks to this, a much more advanced version of the engine was literally manufactured. In turn, a new vacuum measurement chamber and a laser system capable of detecting even the most imperceptible thrust were designed.
With all this, the tests began and, once again, the EmDrive was able to generate a minimum thrust, a force that curiously did not vary even when it should have, indeed, its EmDrive generated thrust even without the need for microwaves in the chamber. It was at this point that the researchers realized that what generated thrust had to be an external factor and, doing the math, they found that This small impulse is consistent with the unwanted interaction between the Earth's magnetic field and the motor's microwave amplifier wires..
