EM-Drive가 화재여서 관심있게 보고 있는데요. 오늘 이런 글을 발견했습니다.
아래 기사에서는 EM-Drive는 기존의 물리학 법칙을 깨트리는 것이며 불가능한 것이다 라고 말하고 있습니다.
돈벌이 수단 밖에 되지 않는다는 말도 하던데요...
정확한 근거를 제시 한 것은 없고요 다만 In-Put Energy가 Out-Put대비 상당히 많을 것이다 이렇게만 말하네요.
얼마전 NASA에서 실험에 성공했다는 내용과 상반되는 내용이라 퍼왔습니다.

Physicist John Baez has another, more colorful word to describe the spate of recent reports about a breakthrough space engine that produces thrust without any propellant. The word starts with “bull–.” I won’t finish it, this being a family-friendly web site and all. Baez himself has softened his tone and now calls it “baloney,” though his sentiment remains the same: The laws of physics remain intact, and the “impossible” space drive is, as far as anyone can tell, actually impossible.

The story begins several years back with a British inventor named Roger Shawyer and his EmDrive, a prototype rocket engine which he claimed generated thrust by bouncing microwaves around in an enclosed metal funnel. Since no mass or energy emerged from the engine, Shawyer’s claim was another way of saying that he’d found a way to violate the conservation of momentum. In Baez’s words, “this is about as plausible as powering a spaceship by having the crew push on it from the inside.” Shawyer argued that he was exploiting a loophole within general relativity. Baez calls his explanation “mumbo jumbo.”
