"HHO" is the "in" term for what is also called "Brown's Gas", which is nothing more than a mixture of electrolysis products. I have a friend who makes custom flutes (draws his own silver tubing, etc.) and uses a water torch. But the thing uses potassium hydroxide (very caustic) to improve ionization and the rig draws about 13A at 240V to produce a fairly small flame. For him, it's probably ideal for items, such as keywork, as the oxyhydrogen flame has less heat (for a comparably-sized flame) and a lower temperature than oxyacetylene, yet is still hot enough to braze with without burning the workpiece. I haven't worked out the cost per BTU, but it could be cheaper. I do some silver-soldering, but it's low-temperature. (1000-1300F), so acetylene-air works just fine. It's the waste of good human intellect and effort that bothers me. Witness how many people jumped on Fleischman and Pons' bandwagon. Didn't France sink a considerable sum into a "cold fusion" research site? I suppose that the only people who made real money were the early palladium futures commodity speculators. Most of the claims made since F&P, including Rossi, are undoubtedly due to poor metrology and a basic misunderstanding of metrology techniques. --Chuck
