OK, here's some calculations. a 9 volt battery has an internal resistance of ~2ohms, which means it can output about 4.5 Amps. Lets assume he pwm it down to a lower voltage with more amps, like 5 volts because amount of hydrogen prudced is based on amount of amps. Now he has about 8 amps. I'd say 8 amps could produce that much hydrogen, especially at an efficient frequency. The battery would only last for about 6 minutes max, but that's enough. The only thing I don't like about this is the brown's gas thing, how does it work? a normal setup would be exploding right now. I know the principle is "mono" hydrogen and oxygen, but I thought that was impossible!
Here's my math 9 volt battery capacity 225 mAH = 7290 Joules. Electrolysis of water rquires 237 kJ per mole, one liter of water can be decomposed to 1200 liters of hydrogen ans 604 liters of oxygen, a mole of water is 18 grams so approx 55.5 moles per liter. He claims one liter of gas, so 237000*55.5/1804=7291Joules. Accounting for errors, he's getting 100% efficiency.
He's actually getting over-unity, by your figures - one extra joule-worth of gas!
What? I was going to post my perpetual motion machine soon, but now I won't bother. Stupid machine just keeps running faster and getting hotter, really annoying.
Brown's Gas was debunked years ago, but there's a "conspiracy" element to the psyche of a BG pundit - They are holding back the research to keep the big corporations rich - which means that, like overunity and other such woowoo, it just won't die.

pure hydrogen does indeed burn blue, but due to how the hydrogen recombines with the oxygen at the point of ignition, it does indeed burn blue. A Brown's Gas Welder also burns blue.

Brown's Gas is a fraud. Even a basic understanding of stoichiometry proves that.
Pure hydrogen does not burn. A mixture of hydrogen and oxygen has a colourless flame. The blue flame in the video is typical of simple hydrocarbons, such as propane, methane or acetylene.
IT WILL ONLY BURN BLUE OR WHITE WHEN MIXED WITH OXYGEN. !!!!!!!!!!!!!!!!!

Sorry, I meant to agree with you that H2 burns clear. Sorry...
Agreed - flagged as spam because the poster probably only want metacafe cash.
Probably? Assuredly! He posted this same fake thing in February, than removed it.
Utter fake.
"HHO" and "Brown's Gas" were debunked years ago (Link - see page three).
Electrolysing water can only produce molecular H2 and molecular O2
Try igniting that mixture at the end of a pipe, and the flame-speed (some thirty times higher than that of methane) will mean that gas-flows of several litres per second would be needed to keep the flame outside the end of the tube, rather than burning all the way back to source.

This is just his version of a Brown's Gas Welder. Commercial versions are available in the U.S. The welder has wonderful properties in that it can weld materials that can not be welded together with traditional welding rigs. To put on one's "X-Files" hat, some believe that the Egyptians and ancient Sumerians knew of this technology. Nice demonstration, but like mentioned before, some explanation of how you made this would be nice.

The appearance of the bubbling gases inside the jar looks edited in.

Without more info I would have to say this is fake. A 9v battery cant produce that much heat.
Can you give more details about the project? I mean the way to achieve electrolysis and seperate the HHO to hydrogen and oxygen etc
looks kinda fake. the reaction in the glass container looks like it was added in after effects.

Is this real? The idea is clearly plausible but idk if it was innovation or nice special effects
