RF resonant cavity thruster
Sign in to saveThe EmDrive is a controversial device first proposed in 2001, purported by its inventors to be a reactionless drive. While no mechanism for operation was proposed, this would violate the law of conservation of momentum and other laws of physics. The concept has at times been referred to as a resonant cavity thruster. The idea is generally considered by physicists to be pseudoscience.

The EmDrive is a controversial device first proposed in 2001, purported by its inventors to be a reactionless drive. While no mechanism for operation was proposed, this would violate the law of conservation of momentum and other laws of physics. The concept has at times been referred to as a resonant cavity thruster. The idea is generally considered by physicists to be pseudoscience.
Neither person who claims to have invented it committed to details about it beyond showing prototypes they have built. While the lack of a published design or mechanism makes it hard to say whether a given object is an example of an EmDrive, over the years prototypes based on its public descriptions have been constructed and tested.
