Welding is much stronger but is sometimes not necessary. The cooler and constant temperature of this invention would be a big plus for brazing. I'd say the big question is how feasible is it to bust the hydrogen/oxygen molecules up and can it someday be feasible to run a car with? A friend and I made up a little simple water buster with a couple pieces of lexan tubes, stainless steel, electric fence box and some wire. We would get a pop like a .22 shell going off about every 3 seconds. Now imagine what the educated people can do. I think it's only a matter of time before efficient membranes are worked out for both a water separation and solar panel.
