The '''EmDrive''' (also known as the '''RF resonant cavity thruster''') is a proposed type of [[reactionless drive]] that was first developed by the British engineer [[Roger Shawyer]] in 2001. The concept of the EmDrive is based on the idea of using [[microwave]]s to create thrust without the need for propellant, which would theoretically allow for highly efficient space travel.

== Principle of Operation ==
The EmDrive operates by generating microwaves using a [[magnetron]] and directing them into a closed, conical [[resonant cavity]]. According to its proponents, the shape of the cavity causes the microwaves to exert a net force in one direction, producing thrust. This would violate the [[law of conservation of momentum]] and [[Newton's third law of motion]], which has led to significant skepticism within the scientific community.

== Development and Testing ==
Roger Shawyer first proposed the EmDrive in 2001 and conducted initial tests that he claimed demonstrated a small but measurable thrust. Subsequent tests by various independent groups, including a team at [[NASA]]'s [[Eagleworks Laboratories]], have produced mixed results. Some tests have reported small amounts of thrust, while others have found no measurable effect.

== Controversy and Criticism ==
The EmDrive has been the subject of considerable controversy. Critics argue that the device violates fundamental principles of physics, such as the conservation of momentum. Many scientists believe that any observed thrust is likely due to experimental error or other mundane effects, such as thermal expansion or electromagnetic interference.

== Potential Applications ==
If the EmDrive were proven to work as claimed, it could revolutionize space travel by providing a highly efficient means of propulsion. Potential applications include [[satellite]] station-keeping, deep space exploration, and even interstellar travel. However, given the current lack of conclusive evidence supporting its operation, these applications remain speculative.
