Isn't there a theorem stating that circles (not ovals) have the most surface area when given a certain amount of material, or most efficient use.

Yes, circles have the greatest surface area for a given circumference. Thus in order to get the most surface area on the lightest piston, you need a circle.

i think we'll just go back to horse and buggy in the future, much more fuel efficient.

Yeah, but the emissions are awful!

That would be quite interesting since Neither CO2 nor air has the hydrogen necessary to create H2O.

A little alchemy anyone?

Could use a Ruby Laser in a sealed chamber. Then when the atoms hit a substrate they are drawn into another combustion chamber. Almost like if you were to use a plasma cutter to heat a material, collect the products air and fumes, then use them for another process.

Umm, so how exactly is this engine going to make more power than the whatever-you-use-to-dissociate-water device consumes? Considering you're talking about breaking the bonds and then reforming them, I don't see where the energy release will be.
