That is SOOO COOL! I'd much rather see a car ran on air than water. And $15,000! Wow! The compact size of the engine being developed in Australia makes the idea of a Jetson's type car easier to dream about since the engine is so tiny. Now we've just got to get them wheel-less.

Mini hoover crafts.
But meanwhile, I'll settle for an Italian minivan, those are hawt.
Thanks FR Turbo and PK!
