But let's explore the claim that the water is "burning." If water burns, what are the reactants and what are the reaction products? If it's hydrogen that's burning, then it was derived from the water by applying enough energy to split the water molecule... and if this is really the case then you've input as much energy in the form of RF as you get back by burning the (allegedly) produced hydrogen. Not necessarily. It could be more, less, or the same depending on the precise nature of the reaction. OK... so would you mind explaining one or more variations on "precise nature" that would make for a meaningful difference in energy? Here's the thing. You stated that "you've input as much energy in the form of RF as you get back by burning the (allegedly) produced hydrogen." I'm merely pointing out that there is nothing about the physics and chemistry here which makes that guarantee. As I went on to say, a complete energy analysis requires that the initial and final energy states must also be considered. If the final energy state is higher than the initial state, then more energy will be input than released in the reaction. If the final energy state is lower than the initial energy state then more energy is released than is input. Total energy is certainly conserved in any case. I'm sure you can see my point here. It's far from controversial. 73, ac6xg |

Whan I say energy I mean *all* energy, including any energy possibly stored as heat because the final products might remain hotter than the orginal products. If you have a point that overrides that trivial case I just used to guess at what you're talking about, then you need to explain it in more detail... not because I'm stupid, but because you're simply not presenting your case unless you do; you're just hand waving. If there is something specific in my comments above that you don't understand, please let me know what it is and I'll be happy to elaborate for you. 73, ac6xg |

The question is should the press or media decide on it's validity and possibly consider the censoring of the story. Some people on this newsgroup are angry because the story has been given publicity that they feel is undeserved and harmfull to the minds of some readers. They want to squash the idea by ridicule or censorship since in their judgement it propulgates falsities about science. If the minority in science who wish to decide what is and what is not harmfull or fruitfull to the community then the study of science itself is not required and neither is debate. Art I guess I'm one of the "angry" one... because this is yet another case of bad science reported to a public that is incapable of telling good science from bad science and which in this case wasn't even offered the opportunity unless it was via knowledge gained from elsewhere. O.K. your complaint is noted. Should the press add a disclaimer of the veracity of the claims? Should one have a trial with the assumption that what is said is correct and not prematually presumed to be false? At what degree level would one have to be a legitamate judge? Should the Supreme Court be councilled before a statement is allowed to be made? Should the President council Congress before he faces the nation? Should not YOU council others before you make a statement aboyut others? Lewellyn made an allegtation about the poor state of education of other than himself should he be stoned to death? This a simple argument over something that was reported and YOU are angry. And you want your comments to be removed, but for why? Do you consider that they may not be valid or stand the test of time? This newsgroup allows you, an unknown to express his thinking as a term of free speech while you on the other hand want to stilt the free speech of others. Your highness, you are much to harsh on those that you judge. Hopefully your house is not made of glass. Art Yes, I think that when the press reports on a perpetual motion machine they're obligated (in a social contract sense vs a legal one) to point out that such things are really impossible. And when they report on a device claimed to burn water that represents a potential energy solution... then I think the times (energy shortages, high gas prices) demand more balance than was provided. The real point being that there was no "debate" in the original story. It was nothing more than a one sided "let's stir them up today" piece. |

... Please point out to me where the press ever claimed it was a "perpetual motion machine" (over unity.) I am afraid I missed anyone claiming that, except some here stating that it wasn't--and the rest of us already knew that--but then, those who are not to sharp keep going around yelling that--just as if someone is claiming it is, strange bunch. Who has the energy to point out to them that it appears a bit insane? Kind of like someone pointing out that the computer in front of 'em isn't a perpetual motion machine! DUH!!! As I have pointed out, and am getting tired of pointing out, this may be the discovery of the century--WITHOUT HAVING TO BE AN OVER UNITY DEVICE!!! IF, and that is a pretty big if, it is real when subjected to complete scrutiny. JS |

... If quantum physics leaves your belief system shattered, then I'd have to say you don't understand quantum physics on even a superficial level... or else you're exaggerating your reaction to it. The math is a real bitch, but the generalized concepts are easily grasped by those who understand classical physics. But that aside, the real point is that quantum physics doesn't leave classical physics as a broken law to be tossed aside. NASA will continue to use classical physics to plot trajectories to the Moon or to Mars. ... OMG! What was I thinking, particles that "wink in" and "wink out" are total boring! ROFLOL!!! ... Are you even for one instant suggesting that "burning" water for a net release of useful energy might be true? ... I pointed out that with engineers and physicists (No, I didn't examine their degrees) it is worth a look, not a bunch of fools booing in the isles ... What gas are we talking about here that can be transported with no loss? The current darling candidate is hydrogen... for which net tank-based transportation costs are tremendous. REmember - or at least realize - that "transportation" includes the cost to compress on the sending end, expand and recompress on the receiving end, plus the classical over the road costs. Then when you figure that the energy density of gasoline is 9000 Wh/l (watt-hours per liter) and for hydrogen compressed to 150 bar (2200 lb/sq. in.) is only 405 Wh/l you can see that transportation costs are far higher per watt-hour delivered. You are stuck in your own world, blinded by your own thoughts ... pipelines carrying hydrogen or hydrogen + oxygen would experience no loss ... ... not to mention the dangers of having a ready made super bomb on every city corner - where a gas station used to be - just waiting for terrorists to set it off. Hydrogen is magnitudes safer than gasoline, kerosene, diesel, natural gas, etc.--due to hydrogens "buoyancy", on escape to the environment, it rapidly escapes upwards, the bulk of heat and energy is directed upwards when burning also ... So, you are one of the, "Yeah, I already knew that" crowd. Good, I needed an example, such as you, to show the group ... JS |

Thanks for the interesting induction coupled plasma discussion. 73, ac6xg Mr Higgins is correct, it is scary what people will believe, even when something obvious is mentioned, like "conservation of energy". I'd like to know what possible "final chemical energy states" might exist here. What miracles occurred to release more energy from the hydrogen? Combining with chlorine? Maybe, but where did the energy to free the chlorine come from? None of the combinations will release more than it took to free the elements from the compounds. I'd love to find out that I'm wrong, though. tom K0TAR |

Every chemical reaction has both an initial, and a final energy state. For the benefit of those in the group who haven't taken a chemistry class, there is apparently a need for me to declare an allegence here. Obviously, water is not gasoline. The tiny flame in the movie is not the energy equivalent of hundreds of watts of RF - except perhaps to a second grader or a journalist. My point is simply that for a given chemical mass, the difference between energy input and energy output equates with the difference between the initial chemical energy state and final chemical energy state of the chemical reaction. This follows from conservation of energy. 73, ac6xg |
