A tentative theoretical explanation for the mysterious, "impossible" EmDrive propulsion system was published in the Journal of Applied Physical Science International in August. First proposed by British engineer Roger Shawyer, the EmDrive is an asymmetric box that looks like a truncated cone, with a standing microwave field inside that—apparently violating known physical laws—seems able to generate thrust and propel the device.
Meanwhile, China's state media claims that the country's scientists have perfected a working EmDrive prototype and are preparing to test it in space. NASA is also funding a feasibility study for an interstellar mission powered by a related exotic propulsion method.
In September 2016, propulsion researchers gathered for a select, invitation-only workshop at an isolated retreat in Estes Park, Colorado. The proceedings and videos of the workshop, sponsored by the Space Studies Institute, are available online.
It will NOT take us to the stars. It requires solar energy to produce the anomalous reaction. The further one travels from the sun, the less solar energy available to produce the reaction. It would be useful for inter-solar-system travel, but not for interstellar travel. To read more, click here.
