This guy is a quack. Removing 800lbs from your vehicle= 150mpg? Yeah ****ing right. By that rational if I take out the seats and saw off the roof of my car I could get 150mpg. Somehow I doubt it.
He also says biofuel is the best because it lubricates the engine, so you never need to change the oil... wtf... leaded gas lubricated valves and stuff, but you still had to change the oil. Hell, if you use a modern synthetic the only reason you really need to change the oil is because the oil gets contaminated, so yeah, you'll still have to change the oil.
Also, I don't see how something 14" deep and 14" across.... let me see.. pi r ^2 * h= well, around 2100 cubic inches in total size. I guess the displacement is possible, but creating that much poewr in such a small engine will = huge amounts of heat in a very small area, so I don't see how the engine could not overheat.
Then the guy blasts some compressed air in it and claims it's working? What a joke. HEy check it out guys! I'm using a pressurized PC duster to spin an old fan! I have a revolutionary engine! It's doing work!
