IBT: The research, entitled "On the exhaust of electromagnetic drive", is published in the journal AIP Advances 6 and is the brainchild of Dr Arto Annila, a physics professor at the University of Helsinki; Dr Erkki Kolehmainen, an organic chemistry professor at the University of Jyväskylä; and Patrick Grahn, a multiphysicist at engineering software firm Comsol.

'British scientist Roger Shawyer devised the EmDrive concept and first presented it in 1999, but spent years having his technology ridiculed by the international space science research community. According to Shawyer, if the technology is ever commercially realised, EmDrive could transform the aerospace industry and potentially solve the energy crisis, end climate change and speed up space travel by making it much cheaper to launch satellites and spacecraft into orbit.
'Yet despite the controversy attached to the technology, since 2012 nine independent studies have been carried out by scientists from China, Germany and even Nasa to try to build and test their own versions of the EmDrive. Although the researchers are not sure why, they have all discovered signals of thrust that cannot be explained.'
