But, but, but its on the interweb, it must be real......Snake oil. 100% pure and unfiltered.
This one looks interesting.
The term Brown's gas refers to oxyhydrogen with a 2:1 molar ratio of H2 and O2 gases, the same proportion as in water. It was named after Yull Brown (Ilia Valkov, Bulgarian: Илия Георгиев Вълков), who suggested it to be produced by the electrolysis of water to be used as a fuel for the internal combustion engine.[4] Later "Brown's gas" and HHO has become fringe science terms for a 2:1 mixture of oxyhydrogen obtained under certain special conditions; its proponents claim that it has special properties.
And can do no meaningful work. Frictional losses will stop it the when a load is applied.Cool! but almost as fun to watch, as watching paint dry...
Electrolysis is used quite often. A company that manufactured Gas Chromatography equipment used electrolysis to supply a hydrogen flame for the detector circuits. It did not take a huge flame to do that either.So, who is to say the properties described as "special", must be attributed to the supernatural? Said who? If people can take water and produce a flame from it!! Better yet, a cutting torch?! I'd say that is a fuel, beyond refute.
