An underwater ramjet, but really kind of a jet pump/ejector ramjet? Substituting expansion of overcompressed air or a compressed liquid refrigerant (so pressure drop expansion or liquid to gas boiling expansion) injection for a conventional combustion chamber in a ramjet. If one gets enough momentum from the injection to to do a standing start, then it gets pretty simple for a ramjet. One of the patents from this seems to show a pod version and a long blade version, that uses 2D ramjets embedded in the blade. Ultimate, you need some sort of high pressure gas source, either compressed gas, liquid boiling into a gas, or a gas generator. I wonder if this can be mixed with a supercavitation drag reduction system like a skival torpedo, supercavitating the ramjet pod exterior from the same gas generator flow?

RIME (Rocket Induced Magnetohydrodynamic Ejector) rocket design for an electric air breather rocket ejector ramjet of sorts. Robs power from the rocket exhaust via MHD generator to power the generator magnets, the air ionizer, and the MHD accelerator.

Interesting that this PDF shows a plug nozzle on the centerbody, when the wikipedia pic shows a more conventional nozzle on the centerbody. Plug makes more sense in terms of flow probably...

Outlet Regulator :
Literally kicks power leeching cords off the wall. Well, more like drops the cord from the power brick.
