For example, Chinese scientists have independently and repeatedly proven the theory of EmDrive. Just last year in fact, a Chinese team built their own EmDrive and confirmed that it produced mN of thrust, which would be sufficient for a satellite thruster. This system could be powered by solar electricity, negating the need for a bulky propellant. However, the work was largely ignored and scientists were still far from convinced.

Nuclear Propulsion Could Be 'Game-Changer' for Space Exploration, NASA Chief Says

The results are in, and it seems Shawyer may have been right after all. After eight days of work, which involved using a highly sensitive low-thrust torsion pendulum within a stainless steel vacuum chamber, the scientists were able to confirm that around micro-Newtons of thrust were produced. Furthermore, they were able to verify that the force was not generated by something other than the test system. According to Wired , that infers it may work by pushing against a cloud of particles and anti-particles that are continuously being produced and disappearing again.

NASA has trodden carefully, however, by not addressing the physics of the system and instead solely focusing on whether it works, and that is what they did. Like Shawyer, Fetta also had a hard time convincing skeptics that the system is valid. The Atmospheric Infrared Sounder instrument aboard the Aqua satellite detects carbon monoxide high in the atmosphere from fires burning in Brazil's Amazon region.
