Nasa has been testing a highly controversial electromagnetic space propulsion technology called EmDrive and has found evidence that it may indeed work, and along the way, might even have made a sci-fi concept possible.
The EmDrive is a technology that could make it much cheaper to launch satellites into space and could be key to solving the energy crisis, if solar power could be harnessed off the satellites and sent back to Earth.
It was thought up and developed by a British scientist called Roger Shawyer, who spent years having his technology ridiculed by the international space community even though Boeing licensed it and the UK government was satisfied it worked.
Nasa has been testing the technology for a while and it confirmed on 29 April that researchers at the Johnson Space Center have successfully tested an electromagnetic propulsion drive in a vacuum, and although it did not seem possible, the technology actually works.
