It is too good to be plausible. The flaw is that heating one half of a
quantum entangled pair destroys the quantum entanglement.

Any such propulsion system implies faster than light transmission of a
signal. I mean, how far away would the drive be when the heating
occured? There's no maximum distance. If the ion drive was at Pluto; it
would heat up right away. That's a signal.

There is *no* experimental proof of transmission of a signal using
quantum entanglement; and there are strong theoretical arguments that
show it cannot be achieved.
