Well k’s many years ago like 15 I did try doing a project for HHO injector for cars, this turned out at the time to be almost impossible but I did have some success with a new approach as it turned out it was not HHO because it did not act like HHO. The name was given the Oz injector.
That changed dramatically with some modifications and yes water went in and came out as an ionized gas, plasma, and it certainly was not HHO I know I have done many tests with HHO.
