Weeks after we heard about NASA confirming that the em drive works, the
chinese make public that they are testing an em drive right now in their
space station...

That will be a HUGE step for mankind Neil. If all that is true of
course. How can something move without sending anything behind to
compense for its acceleration?

Apparently the magnetic field created by the microwaves is asymmetric
because of the shape of the container. And that aymmetry of the magnetic
field pushes the vehicle forward...

A very small effect that could be boosted using super-conducting walls.

WOW!

I was impressed by the NASA papers: that seemed to work? And now the
chinese taking the whole world by surprise: they have ALREADY an em
drive in Tiangong 2???

Probably they started doing that with the first papers and NASA
preliminary reports some years ago. Actually, it is very simple to
build... A very interesting technology.

This could completely transform space travel.
