Hydrogen on demand
This unit does not store hydrogen it uses all it makes as long as 12 volts is applied to the coil. The blow off valve lets extra escape to the atmosphere so it cant build up. The vacuum source i used was from my PCV valve and I injected the hydrogen just before the butterfly valve for the intake the gas mixes with the incoming air and ignites along with the cars gas. This is not for commercial use as I have never stated this or implied this. This is for you the home owner and car driver who does not want to make investments to Bomb Belt schools everytime you buy gas from the pump.
