Nice work. Now that I'm seeing some pictures and some examples of how you innovate (I noticed the rubber plumbing 4" to 2" ? pipe adapter) and your box of wiring and switches your self running generator in the other thread seems even more real. For a minute there seeing that box of switches I flashed back to thinking I was looking at John Titor's Time travel controls.
Did you use a pre-built PWM unit or build your own? Frequency? Right now I'm looking at George Wiseman's gas vaporization plans (which I bought) as he says it is even more efficient than using HHO to supplement gas. But of course not more cost efficient than running off pure water with no gas.
