Been done here before.
There is no gain in breaking water down into it's components just to burn it again. It will take more energy to break it down than it puts out as fuel, no matter the frequency- microwave or infra-red. |

I confess I read the same article (on a comic book forum of all places) today and showed up here to see what you guys thought about it. Can anyone give a more detailed answer as to why they think this won't work?
Is there a detailed analysis out there for me to read about the energy required to break it down contrasted with the energy net gains? Thanks, you guys are the best. Stamen |

Well, casebro had it in a nutshell.
what's happening here is that water molecules are being broken up into hyrdogen and oxygen which are then re-combining. Breaking up the water molecules takes exactly the same amount of energy as you get back from them reacting (burning) to form water again. But of course you can never actually break even because you'll always be losing energy in creating the radio waves only a fraction of the energy of which will actually go into breaking the hydrogen-oxygen bonds in the water. And then you can only get a bit of the energy back if you were to try and run a generator off the burning hydrogen. In short, it's a big waste of energy. Of course if you could break up the water using energy you didn't have to pay the electricity company (solar power, for instance, or microwave energy beamed down from satellites, for a more futuristic option) then you have a ready supply of hydrogen which can be used as fuel. |

Electrolysis of water using radio waves is a new discovery. It doesn't matter that there is no energy gain, it is indeed a new scientific discovery.
Except that the idea has been patented three times already. |

It's amazing how the story is being reported as if there were free energy via this process. Science just doesn't lend itself to contemporary journalism, it seems.

"Superheated Steam" is also water with it's bonds broken by energy. Simply heat the water, under pressure, to 700 degrees. Then let it out of the pipe. It's called "An Explosion".
As I said in my initial reply, infra red energy works just as well as RF energy. |

From the title "Pennsylvania Man Claims to Burn Salt Water"...
I thought "Wow!!! He must be a very bad cook!" |

You might want to check out this post I made:
http://depletedcranium.com/?p=106 One of the visitors to the site made a comment pointing out that what is going on seems to be indicative NOT of hydrogen production but rather of the thermal decomposition of sodium chloride, with the sodium reacting. Look at the video and read what he said and it seems that this "discovery" is not only not a means of producing energy, but it isn't even a good way of making hydrogen Also on Rustum Roy. I have links to some of his stuff here: http://depletedcranium.com/?p=105 Not only is he into the "Whole body healing sciences" he's a homeopath and is into some BS called "Science guided by religion." |

If Rustrum Roy is involved, one should take it with a pinch of salt.

And water electrolysis with electrodes isn't cheap; you need to run huge currents at fairly low voltages through large, expensive electrodes. Given that RF generation is pretty energy-efficient (thank you, miltary radar!) it's marginally plausible that this could be a <em>better way to generate hydrogen</em> than ordinary electrolysis.
But I'd call it unlikely. Question #1: splitting up water releases both H and O. In electrolysis, the H2 bubbles up at one electrode (and goes into the H tank) and the O2 bubbles up at the other (and goes into the O tank). If you're just shooting RF at a beaker of water, aren't you getting bubbles of mixed H2 and O2 (Brown's gas)? That's fine if you want to feed it to a cutting torch, but storing it would be incredibly dangerous. |

Well, you also have to consider the efficiency of not just the radio wave generation but how much ends up being converted to chemical energy. In the video the numbers on the dial were 1-2 kilowatts. That may or may not be the amount of energy of the RF field, but if you need kilowatts of energy to split a test tube of water, that's hardly an efficient way of doing it.
On top of that, the fact that it needs to be salt water and the flame color indicate that the sodium (and therefore chlorine) may be dissociated. So what you are left with would then be a mixture of hydrogen and oxygen, which would have to be separated, and in the mean time is just asking for a big 'splosion. Plus ontop of that you'd have some sodium compounds and a bit of chlorine gas mixed in... I think I'd stick with other means of making hydrogen. And aside from electrolysis there are also regenerative fuel cells, thermochemical, photocatalytic and other means of doing so. I see this concept as having rather limited possibilities... |

The ability to do electrolysis on salt water, without electrodes, without a catalyst, and without producing chlorine, is a huge discovery.

A correction not found with NBC.
If you doubt me, check out the comments made by those who watched the video --- many think it's going to replace oil. |

The flame colour indicates that sodium is present, but says nothing about its current state.
What exactly do you mean by the word "dissociated"? As a chemist, I'd say that it of course dissociated- it's in aqueous solution, and salt is a strong electrolyte. But you may be using the word in a different context. |

Having watched the video, I retract my claim that it might be "vaguely plausible" that this is more efficient than electrolysis. No way is this as efficient as electrolysis. Robinson, what's huge about it? Is there some application in which you'd want to produce H2-O2 gas mixtures from salt water without electrodes? I sure can't think of one. It's no good for H2 production (inefficient, products are mixed), it's not a good source for an oxyhydrogen torch (inefficient, expensive) ... what else is there? The only people saying "this is huge" seem to be the ones who think it's a net energy source. |

It is sad to me what is going on the net with people jumping all over this "The battery in your car could run this and then for fuel you can..."
My response is "OH OH! How about this! We run a generator by connecting it to a motor which is powered by a battery with the generator charges!" I'm still not sure exactly what is going on here, but I am certain that it is not generating energy (Unless there is fusion going on, which I *HIGHLY* doubt) and that it is most probably much less effecient than carbon-rod electrolysis. This is my best guess: Salt water is considerably more conductive than fresh water. The salt water, especially in a properly sized vial, may be acting as a sort of antenna. The RF energy is thus inducing an alternating current (well, not really current because there's no complete circuit. More like a charge) within the water itself. In other words, with each cycle, the top becomes more positively charged and the bottom more negatively and then reversing with the frequency of the RF field. This charge is causing the water - or to be more accurate, brine - to act as it's own electrodes and the charged regions cause the liberation of some of the ions. This forms the bubbles in the water and thus the gas. Of course some sodium and chlorine are released as well and due to the alternations, there's no way to separate the two. That is the best I can infer. Any chemists in the house? Sound plausible? In any case, that would not be that efficient. |

All you need to understand that it is crap is the Laws of Thermodynamics
(very short: heat/energy flows from where it is to where it isn't. YOU always lose!!)(and eventually, all energy is heat, heat is the only thing there is, it is spread evenly throughout the universe: SO the universe is all at a temperature of just above absolute zero (the famous heat-death of the universe) By-the-by that means no planets, no stars, no meteorites, no atoms or molecules, NO MATTER AT ALL, just evenly distributed heat energy and blackness. |

There are two issues here. (Forget the over unity crap, that is just nonsense).
Is it really electrolysis of salt water? Without electrodes? A video doesn't provide much to go on, except that salt water is producing flammable gas when exposed to RF, which IS something novel, and very interesting. But is it electrolysis of salt water? I doubt it, but if it really is, then it is even stranger. But the yellow flame makes me think sodium, so it can't be electrolysis of salt water. Electrolysis of salt water is one of the biggest and most important industrial processes in the world, it is that huge. If somebody came up with a way to do this without electrodes, and with any increase in efficiency, it would be giant. Astounding really. Is that really what we are seeing? What is happening to the salt water? Is chlorine being produced? Is sodium hydroxide being produced? What is the composition of the gas that is burning? What is the composition of the salt water? What is the end product of the burning? Has this been done in a closed system? What if you immerse the RF generator in the brine? Can you generate the frequency underwater with a waveguide, and get hydrogen? What happens if you bubble the resulting gas through water? Through salt water? What is the Ph of the water? How long does it take? What is the rate of production? A thousand questions come to mind. None of them have anything to do with free energy. Getting salt water to give up just hydrogen alone with RF is astounding. If it is also generating oxygen, it is huge. If it is generating sodium and chlorine along with hydrogen and oxygen, it is one of the most astounding discoveries ever. No kidding. Forget that over unity carp, how is this happening? And if it can be dome to brine, can it be used on other dissolved metals? I'm surprised the "News" is focusing on the nonsense and avoiding the science of the matter. Or maybe not. |

Ah, here's the right forum. I saw the story on ctv and wondered how "real" it was, especially once I saw the name Rustum Roy.
http://www.ctv.ca/servlet/ArticleNew...0911/20070911/ The story linked is sourced from the Associated Press, so it may be the same across other places. But the key here, according to RR, is:

Electrolysis is huge for producing hydrogen gas. Electrolysis to produce mixed H2/O2, which is suitable only for immediate use, is a tiny niche market.
Now, it's possible---I don't really know---that hydrogen plants routinely store their product as a cryogenic liquid. In that case, it wouldn't cost much additional energy to separate the H2 and O2 by distillation. I wouldn't dare speculate on the explosion hazard of a distillation column full of mixed liquid H2 and O2 .... ugh. Again ... if the efficiency is worth thinking about, i.e. better than (I think) 80% metered-electricity-to-stored-chemical-energy which you get with electrodes. I think that 80% efficiency is marginally possible for electricity-to-RF-beam ... fat chance of it being 100% efficiency for RF-beam-to-hydrogen. We've already seen how much the water heats up. -Ben |

It requires much less energy to form hydrogen than sodium from aqueous solution.
If sodium does form, it will react immediately with the water to hydrogen. So, yes, it is the hydrogen that's burning, since the sodium (if any formed) won't last long enough to burn. I may not be RR, but I am An Expert. |
