Eh, Im not sure that it would really work out in a car, but in something a little more stationary like a generator, or possibly boat. That it could work out, the main problem that I saw is carrying around all that water at 8.33 pounds per gallon. Though if you had a boat, distilling sea water wouldnt be to difficult, or with a generator distiling tap water as you go could well work out. Manily it depends on the amount of power produced by the steam stroke. And my other concern would be with multiple cylinder engins, it just makes me nervouse. Finally it would cut down on the total number of combustion strokes, instead of all cylinders completing a full cycle every 720 degres of rotation it would now take a full 1080, but hey it sounds pretty cool.
Interesting design, but I think the pros bring along an equal amount of cons. jghc brings up some interesting points. It'll be cool to watch what happens with this though.
thats a pretty cool idea. i think though that combining a steam engine into an internal combustion engine has had to been thought of a long time ago. i heard that steam engines actually get more power from the vacum formed from condensing the steam than the actual steam stroke so im wondering what the power output is like. thats pretty sweet that he has it working though. id like to see how the progress goes.
