Chinese Say They're Building 'Impossible' Space Drive
Sep 24, 2008 3:38 PM
|
Chinese researchers claim they've confirmed the theory behind an "impossible" space drive, and are proceeding to build a demonstration version. If they're right, this might transform the economics of satellites, open up new possibilities for space exploration ?- and give the Chinese a decisive military advantage in space.
To say that the "Emdrive" (short for "electromagnetic drive") concept is controversial would be an understatement. According to Roger Shawyer, the British scientist who developed the concept, the drive converts electrical energy into thrust via microwaves, without violating any laws of physics. Many researchers believe otherwise. An article about the Emdrive in New Scientist magazine drew a massive volley of criticism. Scientists not only argued that Shawyer's work was blatantly impossible, and hat his reasoning was flawed. They also said the article should never have been published.

I seem to recall the scientific community said the same thing about other "wild ideas," things like the world being round and the Earth not being the center of the universe along with a bunch of lessor ideas.
Let them try it. Maybe they can set the scientific and engineering communities on their ears again.

Sir Arthur was indeed a wise man, one of a kind and a genius to boot.

dave - would this "emdrive" significantly improve the speed of rockets, satellites and manned spacecraft? I hope the hell the Chinese know what they're doing.

From what the article says its thrust is comparable to an ion engine but no propellent is needed, just a source of electricity. Ion engines are not speed demons, they need time to get to whatever speed you want, slow but steady acceleration. NASA had a probe called Deep Space 1 that had an ion engine it was pretty successful. If this works, with research and improvements it might get faster.

Hope they know what they are doing too. In concept it almost sounds like the Impulse Engine from Star Trek.
