So the problem is converting linear to rotary motion.
Couldn't you use pressurized air to get around this? I propose a simple engine: cylinder1 is the power piston. Cylinder 1 has a stiff rod that is attached to cylinder2.
Cylinder2 compresses air, which either drives a turbine directly, or
is used as a head to force water into a pelton turbine.
||Naa, the air 'fluid' resistence and air pressure losses are far greater that the mechanical linkage used by acura, or for this matter crankshaft, rod and piston setups.
||This is why we don't all have a gas turbine engine in our car, the mechanical linkage in a ICE is more efficient at converting the energy into rotary motion.
||So, I give the idea a [-] but Im not actually going to vote.
