When I first read this, I thought it was heating the engine block and then injecting water that flashes to stream, driving the power stroke. (So basically a two cycle engine - when the piston is at the top of the cylinder, water is injected, it flashes to steam, that drives the piston down, and when the piston comes back up on the second stroke, an exhaust valve allows the steam to escape. The exhaust valve closes at the top of the stroke, and the process is repeated.
That would "consume" water, but would avoid the messy oil/water extraction step. (It's basically a 6 stroke Crowler engine missing the first four strokes.)
This is a lot more complicated, and the vagueness of the claims makes me think they do not have a working prototype. They are making vague claims of efficiency as well (15%+ efficiency).
I think I'll come and sit in the skeptic's corner with you.
