HHO Tube Cell - Water4Gas Style
This is my HHO Tube cell that puts out a decent amount of HHO. This is with no PWM, it hasn't been broken in, and it's only 1 cell. Most people put in a 6 Pack of these jars in their vehicle. I'd bet 6 of these would really produce some HHO. I'll be trying it pretty soon, so keep an eye out.
