It appears that NASA’s impossible space drive has a Chinese version, and while both versions use the same microwave technology to create movement, the difference is the container type used in each method. The American space agency used a Cannae Drive, designed by Guido Fetta, while the Chinese used an EmDrive, developed by British scientist Roger Sawyer. Both, however, operate under the same principle of using electricity to create microwaves that bounce around in an odd-shaped container. While NASA was rather secretive about its technology and divulged very little about how their Cannae Drive worked, the Chinese and Sawyer published lengthy papers explaining their process.
The American space agency also hinted at movement created by quantum particles popping in and out of existence to a point where the laws of physics are broken. Sawyer’s report makes no mention of quantum particles and makes no claims that defy the laws of physics. Basically, the microwaves within the container exert a force on each end. When the electromagnetic (EM) wave is traveling along a tapered wave-guide and is bounced between two reflectors, the force difference exerted on the reflectors results in the creation of thrust.
In NASA’s impossible drive, the force created was minimal, while with the Chinese EmDrive version, the force created was much greater. The EmDrive created enough force needed to position satellites in space. What makes these tests so exciting is that they quite possibly offer a glimpse of what future space travel could look like. Both drives offer a cheaper and more effective means of providing thrust. When combining this with the drive’s ability to create its own electricity through the use of solar panels, a vision of deep space exploration becomes a real possibility.
There have been concerns that the EmDrive defies the rules of physics, but according to Sawyer’s published paper, no laws of physics have been violated. The principle is based on a radiation phenomenon which adheres to Newton’s Second Law. This was verified by Sawyer’s in-depth review process.
Sawyer further says that a tiny force will be transferred to a reflector as an EM wave attains a certain momentum when traveling at the speed of light. The amount of thrust created is dependent on the value of Q, the effective length of the EM wave, according to Sawyer.
When it comes to space travel, the weight of propellant is a major contributor to overall operative costs. The amount of thrust produced by the Chinese test using Sawyer’s EmDrive is enough to keep the space station in position for years without the need for re-fueling.
The impossible drive test results of NASA created minimal thrust compared to those of the Chinese test using the EmDrive. Sawyer is already moving ahead, and he believes the Q value can be boosted by several thousand. If that is the case, positioning satellites in space will be child’s play compared to what can be achieved. His superconducting thruster could be ready as soon as 2016.
