Chinese building Anti Gravity Drive (Emdrive)

[Treebiter]

I care!

 

["andy"]

Sounds like the sort of rubbish they spout in sci fi movies. I'll eat my entire hat collection if anything comes of this.

thats what the japanese said before 'the' bomb was dropped and what the world said before electricity , etc etc etc



but i agree with the other poster. ill believe it when i see it. stuff like this will happen one day though...

 

[arknor]

its all fantasy the jet engine will never happen either, ion drives? lolwut ever will they think of next emdrives? crazy talk i tell you

 

[r2d2]

Quite possibly in a few years

A hoverbaord would be a very cool toy.

 

[Cybermyk]

All they need to do now is invent the Flux Capacitor to power it

 

[drunkenmaster]

Ironic isnt it that i bring quite a bit of evidence to this post and no one cares and just belittles me, then a post were i just post something strange, i get loads of interest be it flame baits and mild insults......

Evidence, you mean a video, at an angle that in no way proves anything?

Hell you could still fake it but any normal sane person with a REAL device that could actually lift itself like that, would be filmed to SHOW THE DAMN GAP between device and whatever it was rested on. A video like that could be faked, but if this was real, it really worked, the guy behind it would not be stupid enough to not take the video showing the thing lifting.

Wait wait, a guy in China might of tried to build his own one, yet more proof the thing works and isn't a wind up.

Gravity is the weakest force we know, I don't see why it hasn't been broken yet.

I guess the other link, the presentation to the space conference, the british governments funding of the project and the 2010 project is just "rubbish"?

Conservation of Momentum.

BS.

 

[Teki187]

Conservation of Momentum.

BS.

The momentum exchange is between the electromagnetic wave and the engine, which is attached to the spacecraft. As the engine accelerates, momentum is lost by the electromagnetic wave and gained by the spacecraft, thus satisfying the conservation of momentum. In this process, energy is lost within the resonator, thus satisfying the conservation of energy.

The emdrive concept is clearly difficult to comprehend without a rigorous study of the theory paper, which is available via emdrive.com or the New Scientist website. This paper, which has been subjected to a long and detailed review process by industry and government experts, derives two equations: the static thrust equation and the dynamic thrust equation.

The law of the conservation of momentum is the basis of the static thrust equation, the law of the conservation of energy is the basis of the dynamic thrust equation. Provided these two fundamental laws of physics are satisfied, there is no reason why the forces inside the resonator should sum to zero.

The equations used to calculate the guide wavelengths in the static thrust equation are very non-linear. This is exploited in the design of the resonator to maximise the ratio of end plate forces, while minimising the axial component of the side wall force. This results in a net force that produces motion in accordance with Newton?s laws.

kthx

A closed system doesn't lose momentum.

So

The Emdrive is an electromagnetic drive that would generate thrust from a closed system — “impossible” say some experts.

Experts are correct.

StarForce was considerd strong, but someone wiseguys cracked that.

 

[Teki187]

Experts are correct.

Clearly it's not, as the video shows it working, the British government is investing and the Chinese are building one.....

The British government could tell me 2+2 isn't 4. I wouldn't believe them.

And if I was to believe videos, well...

Well you would have to be pretty stupid to believe them. That's a pretty awful example to choose...

 

[Teki187]

You might actually realise that the drive works?

 

[Fenris]

All I see in the video is some random crap turning around.

What exactly is it supposed to be doing?

 

[Jotun]

Does this remind anyone else of primer?

 

[muon]

If I had this device. I'd walk into the physics department at Cambridge University and wouldn't leave until they told me why I was wrong, or I convinced them.

I wouldn't be making youtube videos, or trying to make a device with some random professor in China.

You really think such technology would take this long to propagate?

Common sense plus the fact that this would destroy all of modern physics, physics which has been substantiated by an unimaginable amount of empirical and theoretical research, should allow you to call it BS.

I'm going to go with the experts and their opinion that the device violates conservation of momentum. Since conservation of momentum is maintained in all areas of physics, I struggle to believe that this guy has found a fundamental flaw in every single model we use.
