I don't know much about diesel, for example how energy per volume compares to gasoline, but I think the efficiency difference is in the ball park of 20%, which is not exactly earth shaking. I guess we'd have to look at the actual temperature drop that could be obtained using this magic "humidity carb" in order to say whether it's significant to the total power input. I still maintain that if presence of water in the combustion chamber could significantly improve fuel economy, people would be using it for such, at least in the aftermarket where water injection systems are commonly available, easy to install, and cheap. I have one on my car, and there is no noticeable benefit on fuel economy. Likewise with the turbo, the only "improvement" in fuel economy in my turbo 4 is when you compare to a car of similar power output, like a V6. Compared to a car of the same weight and engine displacement, there is no difference in fuel economy. Whatever heat energy is recovered at the turbo is generally offset by increased heat in the engine itself as the turbo forces it to produce more power.
