Superconducting EMDrive Patented:

"Shawyer describes a new EMdrive thruster design that has a single flat
superconducting plate on one end, with a uniquely shaped, non-conducting plate
on the other.

This is necessary to minimiZe the internal Doppler shift - a change in
frequency or wavelength of a wave for an observer moving relative to its source
- and also keep manufacturing costs down.

* It enables the drive to be easily manufactured
* It will make a viable superconducting thruster easier. Shawyer believes a
superconducting thruster will produce a lot of thrust

Shawyer is working with an unnamed UK aerospace company to develop his second
generation EM Drive, which he says will produce thrust many orders of magnitude
greater than that observed by NASA’s Eagleworks team or any other laboratory."
