yeah, the crower squirts water in after the "blow" stroke (does that sound dirty?) and that generates another power stroke (due to steam). The steam carries away all that cylinder wall heat with it and the process starts over. Sounds phenominal to me. Not to mention, this engine could live in an air-tight engine bay with 0 openings to create drag.
