L'EmDrive?

La nouvelle semblait pourtant si prometteuse:

After months of speculation and leaked documents, NASA's long-awaited EM Drive paper has finally been peer-reviewed and published. And it shows that the 'impossible' propulsion system really does appear to work. 

(...) In case you've missed the hype, the EM Drive, or Electromagnetic Drive, is a propulsion system first proposed by British inventor Roger Shawyer back in 1999.

Instead of using heavy, inefficient rocket fuel, it bounces microwaves back and forth inside a cone-shaped metal cavity to generate thrust. 

According to Shawyer's calculations, the EM Drive could be so efficient that it could power us to Mars in just 70 days. 

But, there's a not-small problem with the system. It defies Newton's third law, which states that everything must have an equal and opposite reaction.

Malheureusement, Thunderf00t nous annonce que c'est... ben... n'importe quoi:
