How about some oldschool antigravity machines? (Remember the old ESJ
Electric Spacecraft Journal? ) I just stumbled upon the following, some
old 1999/2000 conference papers from JF Corum and friends:
EM Stress-Tensor Space Drive, Corum et al, conf proc SAIF 1999

If the mystery-force sums to zero over one cycle, yet violates momentum
conservation (like "Emdrive," lacks any momentum-carrying EM emissions,)
then try giving it single large monopole pulses, cap-discharge and the
like. See if we detect a measurable "kick."
