EMdrive Revisited

[sanman]

Here's an interesting article about a new breakthrough in the manufacture of a superconducting radio-frequency cavity:

If this new cavity were tested for EMdrive purposes, could it reveal a new mechanism for propulsion?

IBTL!

In a nutshell, this is pseudoscience, and we don't discuss nonsense like that here.

What about articles in the scientific literature debunking this? Sorry, there are none. There are no articles in the scientific literature that describe this nonsense, either. It is poppycock. You won't find articles in the scientific literature debunking this because there is no reason to publish such a paper. That New Scientist did is troubling.

That the Chinese have been snookered into investing in it is even more troubling. Then again, they are spending a lot of money to become a spacefaring nation. When NASA was rolling in the dough back in the 1960s they wasted a bit of money on pure nonsense. Apparently the Chinese have been caught in the same trap.
