	Suppose there is just a simple single-ended hydraulic piston. The solenoid valve connects the cylinder to either tank (suction) or pressure. Adjusting the timing controls energy extraction from the moving steam piston inertia at the end of the power stroke and giving it a shove back towards the top end. A second solenoid valve could control a small hydraulically-operated poppet valve to admit steam (with variable cutoff timing).		Suppose there is just a simple single-ended hydraulic piston.

	Marcin says: I looked at this in detail 2 years ago, and purchased plans. When I asked for references of people who built this engine, the inventor did not provide me with any. I became suspicious about the effectiveness of the engine. Since then, I've heard reports from several sources that longevity and performance are questionable. In summary, if this worked as stated, we would see a large number of implementations on the internet. Since these are not to be seen, it does not appear to be a promising design.
