http://HappyHandyman.net Pat diverts the 4-runner's HHO cell Hydrogen generator output to do a volume test, then weld and cook. (Re-wired with10 guage, the hydrogen fuel cell prototype array makes 1800+/-gallons of HHO gas in 30 hours, a gallon/minute (at atmospheric pressure). The gas is 40% Hydrogen by volume, 60% Oxygen. Pat uses 4-cell array of Stainless Steel tubes wired in series from a car battery. The simple flash guard: 1" cigarette butt stuffed in 1/4" ID rubber tube.
