China claims successful EmDrive testing in space

EMDrive electromagnetic drive is used in a spacecraft as an engine EMDrive works with electromagnetic radiation. The people’s Republic of China has tested the space tech in labs, and its proved successful, as reported by Dr. Chen Yue, the Director of China Academy of Space Technology on December 10, 2016.

The traditional engines expel mass to move, but the EMDrive uses electricity to produce movement. It was first built by Roger Shawyer and was a microwave cavity that has a shortened cone that has an end bigger than the second. Electromagnetic energy enters the narrow end with the microwaves that hit the cavity walls and produce electromagnetic resonance.

EMDrive has a low impulse, and because of lack of friction and gravity in deep space, it would cause EMDrive to work at high speed. Engine performance depends on cavity material as well as temperature that impacts the electromagnetic field. This shows that the EMDrive would be relatively successful in the future because they’re built with superconducting components. Satellite design has to be compatible with the EMDrive to work well. So, the test is ongoing to check the efficiency of EMDrive.

China has not released pictures of the EMDrive, but NASA published a different one named Eagle works. EMDrives are perfect for exploring deep space, as they do not need refueling. Only one power source is needed to run EMDrive, such as solar energy or a reactor.
