Next Big Future reports (like many) the worrying results of Dr Tajmar with his EmDrive experiments.
It seems his thrust can be attributed to twisted pair in earth magnetic field.
The paper is there

Tajmar is finding more magnetic interaction from cables. He is not conclusively saying that is all that is happening with EMdrive or Mach Effect but he thinks it is a significant error source for such tiny thrust measurements.

If confirmed it may be the end of EmDrive hope, but it is not so sure.
For example, Harold White in his paper report a "null experiment" (in fact putting the cavity so it does not cause any effact on the torsion balance) with no thrust

arc.aiaa.org/doi/pdf/10.2514/1.B36120#page=9

Shawyer reports also tests where this possibility may be ruled out
emdrive.com/faq.html

The most worrying is that he have no thrust finally, once removed what othet experiment probably have removed too.

But this may mean that Dr Tajmar have removed another artifact with his experimental method, that other did not consider.

Seems due to a bad design choice (only 2W and unshielded very long wires). It is incredible that a private individual (@Monomorphic) in the US with little money is building a much better setup design than NASA's Eagleworks and TU Dresden combined.

Micael McCulloch, creator of MiHsC theory, notice that Tajmar 2018 results is really an outlier in his catalog...

Just been reading Tajmar's new paper on the #emdrive & #MET in which he seems to debunk them, but he is not testing an #emdrive since his thrust is 50 times less than what it shld be given his stated setup. I have plotted the Tajmar2018 test compared 2 the others. Xtreme outlier:
