Hopefully this belongs here, I see a few other threads on hydrogen power, so I guess I am safe. My brother showed me a clip of an article off some new program about a man named Denny Klein who recently "patented his process of converting H2O to HHO." He was using the result in weilding, but he was able to stick his hand in the flame and still when he turned it on a piece of metal, it melted. Then he had the idea of using it to power his car, claiming that in the results it took only 4 ounces to travel 100 miles in his gas-water hybird car. I know I read recently on these forums that there was someone who tried to sell a car that ran on water, with the claim that his catalyst helped break down water into hydrogen and oxygen, but I could not find it. They also explained the law of thermodynamics that refuted whatever the nut claimed about his engine. This would not happen to be the same guy, would it? Here's is the link my brother got this from: http://digg.com/technology/Water_Fuel_-_HHO_Gas - You can watch the video clip here. I tried reading what everyone was saying, but on there even the uninformed seemed to act as if they knew what they were talking about, which quickly turned confusing. To finally get around to my question, could this process ever produce net energy (he already admits it uses more than it produces)? And what is HHO; hydrogen bonded to hydrogen and oxygen, instead of oxygen bonded to two hydrogen perhaps (strikes me as odd, because H2 is stable by itself)?
