Q: Would English teachers working in China qualify for .... weekly space flight?

Much sought after by space agencies, the system could potentially allow for travel to Mars in weeks.

Scientists in China claim to have developed a working prototype of the EmDrive, according to state TV, with a test due to take place in space in the near future. Developed by scientist Dr Chen Yue at the China Academy of Space Technology (CAST), it would put China’s space agency ahead of NASA.

NASA’s Eagleworks paper on EmDrive space propulsion technology has finally been published. It shows that the electromagnetic drive rocket propulsion system actually works, but seemingly violates...

rt.com

The EmDrive is key to the future of space exploration, eliminating the need for a conventional propellant to produce thrust. “For every action there must be an equal and opposite reaction,” Newton’s Third Law states, emphasising the need for propellant in all modes of travel.

China claims to have defied that law, producing an EmDrive that produces thrust by bouncing microwaves around in a closed container with no propellant required. In theory, this is the equivalent of “trying to pull yourself up by your shoelaces and hoping you’ll levitate,” Steven Thomson of the University of St Andrews said in 2015.

A leaked paper from NASA last year showed the drive was possible and that the space agency was busy at work on their own version. Their theorized model could generate approximately 1.2 millinewtons of thrust per kilowatt were the power input to be scaled up.

In comparison, one of the most powerful thrusters in development and powered by ejecting plasma, the Hall thruster, generates about 60 millinewtons of thrust per kilowatt, reported Next Big Future.

I'm not an English teacher, but I'm smart enough to realize the in China, a country where QC means Quit Caring, it would probably be a one way trip, and they would require a Z Visa, and a PSB visit if I arrived. It has fubar written all over it.

I did not open the link, but from the description it seems to be very similar to an industrial bowl feeder.

Accelerate a mass forward, it hits a wall and the wall is propelled forward. As it rebounds, it has lost speed, and hits the back wall, imparting energy, but not as much. If accelerated forward again, the result will be a net forward force.

Energised forward stroke, spring powerd back stoke with lower impulse.

Newtonian physics requires friction for this to work. Air friction for example, or gravity.

Interesting idea.

Comments on Yahoo-gle link are interesting:

"I've followed space exploration since the 1960s and am quite familiar with NASA's EM drive. I have never once heard it described as a "warp drive" by anyone but ill-informed reporters looking for a click-bait headline."

Yep, sure they can defy the laws of physics....

 

(just do a search for "Chinese journal retraction" and see what you get!)

A:I think the first "not smart" thing you did was to think of everyone as a subordinate. They are in fact your team members. You are also a team member and your role is to supervise, not flex your muscles. It drives you nuts when your boss does this and then you do exactly the same thing. Think about it. Adapt, change, bend the rules and be more efficient. -- iWolf
