If only the theory mentioned in this article were true...
Chiao and co ask how big is this effect of a gravitational wave on a thin superconducting sheet compared to the effect on an ordinary conducting sheet. The answer? 42 orders of magnitude bigger....then just by putting two superconducting sheets together we would have gravity wave lasers. They'd probably be practical within twenty years, and Lord knows what we'd have within a hundred. Unfortunately this probably violates the equivalence principle and is likely nonsense:
First, Chaio assumes that coopers pairs fall differently than normal matter in a gravitational field...which basically means violation of Equivalence Principle....and there is no physical evidence for that assumption....neither does he give a rigorous treatment to prove that ASSUMPTION.In other news, scientists studying the Alcubierre warp drive have found yet another way it would not work: in addition to being unstable, non-steerable, non-startable, and requiring planet-sized masses of unobtainable negative energy, it would also cook the occupants as soon as you exceeded the speed of light.
