The gist is that a retired TV station owner, searching for way to cure cancer came up with a radio frequency generator that can “separate water into hydrogen and oxygen” and that a test tube of saltwater (why saltwater? regular water won’t work?) will sustain a 1500 degree flame while in the beam of the device.
I found this brief discussion on Physics Forums, which doesn’t shed much light on the subject, apart from pointing out that there’s likely more energy going in than coming out (no surprise there).
2500°K is 4040°F, so unless the reported temp is wrong, Kanzius is getting less than 4% H[sub]2[/sub] at equilibrium. Still 3,000 F is hot enough so you’d expect some water to split.
How much is some?
Well his flame looks like something you might get from, say a 60 ml/min source of H[sub]2[/sub] (STP etc…) That’s 0.0027 moles of H[sub]2[/sub] per minute. At 18ml/mol for water that represents a dissociation rate of 0.049ml of water per minute From a ~10 ml test tube, that’s not very much.
I’m not seeing anything here that can be explained by localized heating within the test tube. It’s got to be localized though, because the water in the tube hasn’t shot out the end, boiling hot.
