Engine of the future?
hey guy's, don't know if anyones seen this yet, but this guy's building some seriously amazing engines. Their currently going into production in other country's, and he started building them in his garage at home.
He claims they never need an oil change because they only have 2 moving parts. Check out that valve system
Check out some of the video for interviews etc.

Re: Engine of the future?
seems like a decent idea, but using un-lubricated bearings is excessive - why use exotic materials when they arn't really needed? i guess it's for bragging rights.
i recall reading about a company making flat-4 engines whose crank looked like a pair of rotors from an RX-7, rotating in opposite directions. the pistons of opposite cylinders were tied directly together by the connecting rod - it's just a solid beam. the beam/pistons would ride on a pair of rollers around the perimeter of the two crank rotors. the result was the same reciprocating motion you get in todays engines, but it doesn't have to fight the side to side forces created by a typical crankshaft/connecting rod combo. it's like having the ultimate rod/stroke ratio.
