The Chinese Just Did a Soft Disclosure on Free Energy
- Jan 12, 2017
Chinese scientists just announced that they have successfully recreated NASA’s ‘impossible’ EmDrive, an engine that works entirely on electromagnetic radiation. The prototype is not in a garage-filmed Youtube video, but published in full detail in the peer-reviewed journal Propulsion and Power.
Scientists from the Chinese Aerospace Science and Technology Corporation (CASC) claim NASA’s results “re-confirm” what they’d already achieved.
The free-energy “reactionless” Electromagnetic Drive uses only electricity, and defies widely accepted laws of physics. The Emdrive has already been launched into space, and at a press conference in Beijing, researchers said that the Chinese plan to use it to power satellites, “as quickly as possible.”
In another paper the propulsion theory behind the EmDrive is explained more thoroughly,
“At first sight the idea of propulsion without propellant seems impossible. However the technology is firmly anchored in the basic laws of physics and following an extensive review process, no transgressions of these laws have been identified.
The principle of operation is based on the well-known phenomenon of radiation pressure. This relies on Newton’s Second Law where force is defined as the rate of change of momentum. Thus an electromagnetic (EM) wave, travelling at the speed of light has a certain momentum which it will transfer to a reflector, resulting in a tiny force.
If the same EM wave is travelling at a fraction of the speed of light, the rate of change of momentum, and hence force, is reduced by that fraction. The propagation velocity of an EM wave, and the resulting force it exerts, can be varied depending on the geometry of a waveguide within which it travels. This was demonstrated by work carried out in the 1950’s. (CULLEN, A.L. ‘Absolute Power Measurements at Microwave Frequencies’ IEE Proceedings Vol 99 Part 1V 1952 P.100)
Thus if the EM wave travelling in a tapered waveguide is bounced between two reflectors, with a large velocity difference at the reflector surfaces, the force difference will give a resultant thrust to the waveguide linking the two reflectors. If the reflectors are separated by a multiple of half the effective wavelength of the EM wave, this thrust will be multiplied by the Q of the resulting resonant cavity, as illustrated in fig 1.”
The engine could also send people to Mars in as few as 70 days, according to the scientists’ findings.
In a leaked paper, NASA puzzled over the ‘physics-defying’ thruster which continuously provided positive results when tested. The findings were disclosed by a research group led by Dr. Harold “Sonny” White at the Johnson Space Center (JSC) in June of 2014, which made waves throughout the scientific and technical communities.
However, Prof. Juan Yang in China was publishing her research into EM Drive technology as early as 2010. With the latest ‘soft’ disclosure that the EmDrive prototype made by Chinese scientists, is indeed working, we may have just observed China beat the U.S. to the proverbial free-energy finish line.
The EmDrive was first proposed as an alternative to rocket-fueled engine technology by British engineer Roger Shawyer. He generated electricity to generate movement simply by bouncing microwaves around a cone-shaped chamber that would then create radiation pressure. The device used no propellant, and so there was no exhaust.
The EmDrive is already being tested on thrusters on the Tiangong 2 and X37B space planes.

p=E/c
E=energy
c=speed of light
This mean the FORCE=dp/dt is given by dE/cdt, that is the power divided by c. Let us say our thruster has the same power as saturn v rocket. This is around 40000000 w. This mean the force that will accellerate our thruster will be 0.13N. Lets assume our thruster is around 100kg. Then accellaration will be given by 0.13/100=0.0013m/s^2. So to get our thruster to attain the speed of a car, it takes about one week!
If the saturn v thruster did accelerate to the speed of a car in just a matter of minutes, and yet its power consumption is the same as our em drive, then it means that in the latter, much of the energy is not changed to kinetic energy as desired!
And btw my calculation assumed that em thruster was operating in vacuume. adding the friction might as well make it impossible!
The article goes ahead to apply SR innapropriately. He says that the radiation plus the cavity, when viewed as a single system ignores SR (Special Relativity). This, he says, is due to the fact that the cavity and the radiation are in relative motion with respect to each other, ergo, they cannot be sayed to be the same system. Right? Wrong!! Even if the cavity and the radiation are STEADILY moving at different speeds, they are ACCELERATING at the same rate! Acceleration, not steady motion, is what defines 'same system' when dealing with Newt's laws of motion.
Upon exermining the diagram of an EMdrive thruster, one should instantly see that it must violet Newt's third law of motion for it does not allow the 'smock' to be ejected out of the accellerating system albeit the EM wave in this case is playing the role of the smock.
However, the article's confusing explanation does not apply the Newt's third law appropriately. It is true that the action force exerted by the radiation at the wider edge of the thruster is greater than the action force exerted at the narrower edge. This is due to their differing surface area. This mean that the reaction force at the wider edge is greater than the reaction force at the narrower edge. Ergo due to reaction forces, there is a resultant force that tends to push the thruster towards the narrower end. But to account for the net force that accelerate the thruster, we donnot only consider the reaction forces. The ACTION FORCES are equaly unbalanced and they tend to accelerate the thruster towards the wider edge.
