Conquering space is a dream far off in the future. For now, humankind does not have the technology needed to reach the deep ends of the galaxy as we see in TV shows such as Star Trek or Andromeda. However, more and more inventions are being brought to life in order to propel us further. One such invention has been recently confirmed by NASA and be a could ground-breaker in space propulsion.
The invention is a spacecraft that could be able to generate thrust without propellant. It is the creation of US scientist, Guido Fetta, who built a propellant-less microwave thruster and persuaded Nasa to try it. The test results presented at the 50th Joint Propulsion Conference in Cleveland, Ohio, were positive. Guido Fetta explained that his invention called “Cannae Drive” functions as a “resonating chamber for microwave radiation”. Microwaves are bounced in the closed chamber. This causes an unbalanced force that can be used to create a small amount of thrust.
“Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma,” explained NASA, though they did not explain in further detail exactly how the device operates. However, such an invention would definitely cut the cost of satellites and space stations.
Other inventors have been working on propellant-free thrusters for some time. One such example is the EmDrive created by British scientist Roger Shawyer. His technology was recently replicated by a group of Chinese scientists. Unfortunately, their experiments have gained little popularity in the West.
What do you think of this new invention tested by NASA? Will it allow us to discover space farther than we have ever been able to?
