You’re probably catching on by now. I’m a major fan of retro, and therefore, my first car was this 1965 Ford Mustang.

In pursuit of better gas mileage, I built a dry-cell HHO generator (from a lot of research online). The system works by splitting water into hydrogen and oxygen gas (HHO, or “brown gas”) through electrolysis and then feeding the gas into the intake manifold of the car. When the hydrogen is ignited in the combustion chamber, the flame propagation rate is much higher than that of vaporized gasoline. Therefore, the addition of hydrogen provides a more complete combustion of the air-fuel mixture.

I used potassium hydroxide as the electrolyte in the cell. The initial tests showed an improvement of approximately 4 MPG. Not bad at all!
