It's been around a while, but the discussion is far more productive and informative than what George has been providing.

Here is the Smokey Engine from Hot Rod:

What Ever Happened To Smokey's Hot-Vapor Engine? - Hot Rod Magazine

I am starting a thread to continue this discussion outside of this thread.

The difference between these systems and George's system is the temperature. George has a cold vapor system while these examples use hot vapors. I am assuming the heating gas causes it to vaporize much faster than if it is cold? From these articles, it also seems that those hot systems are more complex too.

It is very hard to believe George's system works because he has no way of regulating the amount of vapor going into the engine, if any vapor is actually going in the engine at all. Then, we get back into the EFIE discussion. Is it the EFIE leaning out the engine and causing the claimed MPG increase? Wasn't that the same argument with the HHO systems?? If George had provided more credible research, aside from links to his own website, this concept would be easier to believe.
