Fraud - Burnt fingers
Don't know if it's been mentioned in that big discussion down there, but I have seen a video of someone selling a HHO / browns gas generator on youboob - it appeared when the site first showed up or even before that. The guy in the video is using a full sized gas welding torch and claims the flame 'automatically adjusts' it's own temperature to that which is suitable for the thing being heated - e.g. the gas it's self somehow 'knows' how hot to burn. I believe he went as far as to claim he could put his hand in it and not burn himself, but didn't.
I have also seen someone else echo this comment on a youtube video this week, showing that it has spread around to some extent.
Paper on Brown's Gas with References and Chromatographic Data
There is a number of people talking about the 'Brown's Gas' or HHO or Oxyhydrogen having had some actual laboratory work done on it and this paper is available: [] The conclusion made in that paper (and yes it has a full and detailed set of references) is that when the electrolyser is operated with AC or pulsed current the gas generated is of a different composition, according to analysis spectrometry, there is indeed both diatomic oxygen and hydrogen as well as some small amount in the monoatomic ionised state, but also an electrostatic/plasma modified state of water in which the hydrogen bonding is neutralised with electrons and there is unmodified water, as well as detectable peaks of what the author says is the expanded state. Having watched numerous videos showing various types of torches, there is no question that those claiming to be showing a brown's gas torch are definitely showing something different to the equimolar electrolysed diatomic oxygen/hydrogen, the pure hydrogen gas mix burns a tiny white flame that throws heat 5x or more distance of the visible white flame, whereas there is other ones that show distinctly a golden orange/yellow flame that when applied to metals rapidly heats them to white hot. A test of acetylene versus brown's gas versus electric arc showed that the oxides of tungsten generated by a browns gas flame contain a different oxide composition that resembles the arc generated oxides. It is one thing to rightly reject clearly nonsensical or fraudulent claims made by people who don't even know what quantum energy levels in oxidation states are, and another to look at a white hydrogen flame made by a DC electrolyser versus the yellow/orange flame made with devices running lower voltage AC current without the obvious difference being noted. — Preceding unsigned comment added by 126.96.36.199 (talk) 13:16, 16 December 2012 (UTC)
- The paper you cite is not peer reviewed, and is published on a fringe science web site. We cannot use unreliable sources and original research. VQuakr (talk) 23:21, 16 December 2012 (UTC)
Welds steel? I don't think so
Where is the proof that this can weld steel? It's probably very inefficient due to low specific heat. This is another borderline fact on this webpage. It may braze and do some welding but it isn't efficient.--188.8.131.52 (talk) 20:35, 8 March 2013 (UTC)
It would weld steel, for sure it wouldn't be efficient, but it would do it. Assuming a proper oxygen hydrogen ratio. It would definitely work for aluminum. — Preceding unsigned comment added by 184.108.40.206 (talk) 21:43, 16 November 2013 (UTC)
While there is a lot of fringe science around hho generators. An hho generator by itself would probably not create an appropriate mixture but would require an addition of either hydrogen or oxygen to reach high temperatures. 
I don't understand how something can be a borderline fact? It is either a fact or it is not. In this case it is clear that a mixture of oxygen and hydrogen can be mixed and ignited to a temperature greater then steel. It also has a clear history of being used for welding in the past. ^ P. N.

Applications (addition) Supplemental Fuel
(Source provided) http://www.sciencedirect.com/science/article/pii/S0360319910013595
HHO (Hydroxy) gas was used as a supplementary fuel in a four cylinder, four stroke, compression ignition (CI) engine without any modification and without need for storage tanks. Its effects on exhaust emissions and engine performance characteristics were investigated. HHO system addition to the engine without any modification resulted in increasing engine torque output by an average of 19.1%, reducing CO emissions by an average of 13.5%, HC emissions by an average of 5% and Specific Fuel Consumption by an average of 14%.(source link)
I have found a report that proves not only that a supplemental HHO gas will reduce emissions and reduce fuel use, but that it also has another commonly used 'nick-name' which could be also be added to this page.NeiallsWheel (talk) 03:14, 11 March 2013 (UTC)
This paragraph is worded in a strange way. I am not familiar with the so called "fringe science", so that may be why this is here...but I would say something along the lines of:
"Theoretically, the energy released by the combustion of oxyhydrogen is the same as the energy required to generate it (by electrolysis or any other means).In practical systems however, there will always be some loss of energy in either step, and the combined generation and combustion of oxyhydrogen will have a net loss of energy."
