EmDrive: Finnish physicist says controversial space
propulsion device does have an exhaust:
"A new peer-reviewed paper on the EmDrive from Finland states that
the controversial electromagnetic space propulsion technology does
work due to microwaves fed into the device converting into photons
that leak out of the closed cavity, producing an exhaust.
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."
