DieselPower said:Bruce Crower of Crower Cams has been working on a 6 stroke engine. It adds two strokes to a conventional engine in which water is injected into the cylinder thereby turning the additional two strokes into (more or less) a steam engine.

There is actually alot of interesting technology going on in the engine field. Everything from modern steam engines to 92 % efficient gun engines to almost 100% efficient Rotary Compressed-Air Motor's.

Interesting stuff here. I really gotta say; I don't know if I imagine this, but there is a lot of research going on today. It will probably be some guy working in a backyard garage that sees something and developes it. It will be a breakthrough that will send gasoline back to a quarter a gallon + tax. The sad part, the oil companies will still make a lot.
Cheers
