These are always simple to debunk guys. An gasoline engine is roughly 25-30% thermodynamically efficient. Lets say that his mustang is a 25mpg car to start with. Even if he got his engine up to 100% thermal efficiency (that’s with an exhaust temperature at 0 degrees Kelvin), his car could only get 100 MPG. Basically he is claiming to extract more energy out of the fuel than is in the fuel! That’s the problem with these guys who make ludicrous claims, not only do they make claims we know not to be true but they make claims that are in total violation of the laws of physics. Unfortunately someone had to give it coverage.
