From today's New Zealand Herald newspaper (30 July, 2015) ...
Solar propulsion drive a gateway to the stars
---------------------------------------------
Interplanetary travel could be a step closer after
scientists confirmed that an electromagnetic propulsion
drive, which is fast enough to get to the Moon in four
hours, actually works.
The EM Drive was developed by British inventor Roger
Sawyer nearly 15 years ago, but was ridiculed at the
time as scientifically impossible.
It produces thrust by using solar power to generate
multiple microwaves that move back and forth in an
enclosed chamber. This means that until something fails
or wears down, theoretically the engine could keep
running forever without the need for rocket fuel.
The drive, which has been likened to Star Trek's Impulse
Drive in the Starship Enterprise, has left scientists
scratching their heads because it defies one of the
fundamental concepts of physics - the conservation of
momentum - which states that if something is propelled
forward, something must be pushed in the opposite
direction. So the forces inside the chamber should
cancel each other out.
However, in recent years NASA has confirmed that they
believe it works and this week Martin Tajmar, a
professor and chairman for space systems at Dresden
University of Technology in Germany, also showed that
it produces thrust.
The drive is capable of producing thrust several
thousand times greater than a standard photon rocket
and could get to Mars within 70 days or Pluto within
18 months. A trip to Alpha Centauri, which would take
tens of thousands of years right now, could be achieved
in just 100 years.
"Our test campaign cannot confirm or refute the claims
of the EM Drive, but intends to independently assess
possible side-effects in the measurements methods used
so far," said Tajmar. "Nevertheless, we do observe
thrust close to the actual predictions after eliminating
many possible sources that should warrant further
investigation into the phenomena."

Until they produce a working model that can be installed in space ships,
bring a bag of salt.
And if it does work: Cool!

They must already have a working model to be able to test it and it
seems to be doing something that gives "thrust close to the actual
predictions" ... whether or not it can be scaled up to spaceship sized
usage is a different question though.
