Hey mate yep i have one. It was a project of mine couple years ago. I got it to produce hydrogen and made some decent bangs by filling up condoms and putting them over a flame
I hooked it up to an old car and it worked i guess but no noticable difference. I have a diesel car that i never felt confident enough to hook it up to. Was bit worried about getting water in my engine and was cautioned by a mate who knows cars inside out to be very careful so as not to bugger up the timing...but i have a bubbler/spark aresster now that wont let water in. I will get around to putting it on my daily drive one day.
