NASA Tests Fuel-Free Engine That "Can't Be"

The American Space Agency has been testing new space technologies throughout its existence. But the results of their latest experiment may be the most exciting in NASA history. Earlier this week, scientists at the Eagleworks lab announced the successful testing of technology that allows an engine to generate microwaves of thrust without using traditional fuels. If the results of the experiment can be confirmed and expanded, it could lead to the emergence of ultra-light, ultra-fast spaceships that can take a person to Mars in a matter of weeks.

NASA's test bed is based on a model of a new space engine called Cannae Drive. His idea is that microwaves "jumping" inside a special container can create a difference in radiation pressure, as a result of which a thrust is formed at one of the ends of the container. By the way, a similar technology EmDrive has already been tested by Chinese and Argentine scientists. And in 2006 the British scientist Roger Schauer presented a model of an engine developed using this technology.

The volume of thrust generated in the NASA tests was only 30-50 micronewtons, which is even less than in the experiments of Chinese scientists. However, the fact of creating thrust without using a fuel source was recorded, although this, it would seem, contradicts all the laws of physics.

The NASA team built two Cannae Drive engines. And one of them, not intended for launch, also started working. As the scientists write in their report, "thrust was observed on both test objects, even one that was designed with the expectation that it would not generate thrust." This suggests that the technology "produces a force that cannot be attributed to any known electromagnetic phenomenon."

There are many reasons to make skeptics question the new technology. At least the fact that the inventor of Cannae Drive, Guido Fetta, does not have a sufficient degree. Nevertheless, the results obtained by NASA scientists confirm the prospects of the development and guarantee its further research.
