A New Concept in Spacecraft Propulsion
Satellite Propulsion Research Ltd (SPR Ltd) a small UK based company, has demonstrated a remarkable new space propulsion technology.
The company has successfully tested both an experimental thruster and a demonstrator engine which use patented microwave technology to convert electrical energy directly into thrust. No propellant is used in the conversion process. Thrust is produced by the amplification of the radiation pressure of an electromagnetic wave propagated through a resonant waveguide assembly.
China Unveils Physics-Defying Engine for Deep Space Exploration
Chinese scientists claim they have developed a working model of a microwave engine, which defies the laws of conventional physics, CCTV-2 reported.
The TV channel provided no details of the EmDrive microwave engine, saying only that it would soon be tested in space.
The EmDrive is built around a microwave-generating magnetron and a resonator, which accumulates the energy of their fluctuations. This generates thrust, which can’t be explained by the conventional energy conservation law.
The magnetron pushes microwaves into a closed truncated cone, driving them against its short end thus propelling the craft forward without producing any exhaust.
This differs from the type of propulsion currently used by spacecraft, which burn large quantities of fuel to generate a massive amount of energy to rocket the craft into space.
Scientists believe that a rocket propulsion system based on electromagnetic drives engines could enable humans to reach the outer fringes of our solar system in a matter of just a few months.
A report earlier published by NASA specialists said that the EmDrive indeed generates “constant thrust” using neither fuel nor creating any directed radiation pressure – a phenomenon, which experts say flies in the face of the universally —recognized law of conservation of momentum.
Electromagnetic drive engines, which require no fuel, could pave the way for manned missions to Mars, Jupiter and its moons, asteroids, and eventually to deep space, which is something that China plans to accomplish in the next few years.
China's State Council has released a white paper about its ambitious space program, including the first soft —landing on the far side of the moon in 2018, and a Mars mission to carry out orbiting and roving exploration before the end of the decade.

Underlying princeple Kinetic Energy from microwaves. An EMDrive doesn’t burn propellant. It’s not supposed to work
The waves are produced Via a megatron (Also used in Microwave ovens) The Containment structure is known as a radio frequency (RF) Cavity. It traps traveling waves.
The reflections create a force they than exit the cavity EMD Theory means…
No restoring force = Gained Momentum
Now for the physics
Multiple reflections occur at each end plate
More Reflections = More force transfer
Large Q factor = More reflections
Wave/Cavity Velocities ara independent. The wave speed is not to the two velocities combined. Acceleration of the cavity requires no external reference. This Means its an open system. Thus transfer is momentum is possible.
Now For The explanation
“The Cavity accelerates due to energy transfer from the wave; thus momentum is conserved”
The Unruh Effect
“Photon Pairs are created with one out of phase, these photons cancel out during the pocess leaving no detectable EM Radiation.”
Is İt Viable?
Pros 7 different publications these all agree with trust predictions. Newtonian solutions exist.
Cons Thrust test still too small. Some tests showed opposite thrust. Some tests may have false positives.
“It is still too early to make definitive predictions. Spekticism and enthusiasm are great tools, but our support for more research will help mover is forward.”
