There's one thing we can count on, for sure, no question, no doubt: Whatever magical catalyst is found, whatever wonderful principle is discovered, whatever bonds are broken. . . It will require more energy to turn the water into hydrogen and oxygen than you'll get back when the hydrogen and oxygen are recombined. By any method -- burning, in a fuel cell, whatever. You can take that to the bank. Anyone claiming otherwise is ignorant, delusional, a charlatan, or some combination of those. Anyone believing it is sadly lacking in the most basic of science education. Roy Lewallen, W7EL Yep, but the ignorant will never realize or admit they are ignorant and the snake oil salesman always has a job. -- Jim Pennino Remove .spam.sux to reply. |

Actually it seems that it has gone beyond that when you see the outcry against the Gaussian antenna or even boiling water. Do Americans really believe really believe that all is known and it is a waste of time to experiment? That if you are educated under the American system you have the ability to determine before hand what will work and what will not work? As an immigrant I was asked by the media the other day do I believe that immigrants that do the work that Americans wont do have a different aproach to life? I pointed him to read this newsgroup and make up his own mind , but I also did tell him to look up history to see how past Empires were lost, but I am not sure that he got my point Art |

The first resonant peak of the water molecule is around 1THz, while at the microwave operating frequency of 2.45GHz there are no resonances of the water molecule. The 2.45GHz frequency has no particular connection to the resonant frequencies of candidate food molecules.

I can vouch for the fact that heavy rain and spray can result in 100% obscuration of ship radar targets. Aircraft also use radar to detect storms. The severity of the weather ahead is determined by analysis of the probable size of the water droplets in the cloud, which affects the level of the radar return. While water molecules may have an inherent resonance at 1 THz, it is generally accepted by the scientific community that microwave ovens work by exciting water molecules, amongst others, in food. I can't recall ever cooking anything in a microwave that wasn't wet or at least damp. Well I have tested some bits of plastic for suitability for use at RF, but that wasn't for eating - and the wife was out!!! I am happy to accept that there is no direct correlation between the resonant frequency of a water molecule at 1 THz and a microwave oven magnetron operating in the Ghz range. However, microwave ovens will heat even distilled water quite effectively and heating is defined as an increase in vibrational energy of molecules. So however the process actually works, some principle of resonance must exist to allow the excitation of the water molecules to occur. Either that, or microwave ovens actually work by heating the food with infra red radiation derived using waste heat from the magnetron and we have all been fooled. :-) Mike G0ULI |

... Art: Well, your point is well taken here. Correct. They want the news media to filter all for them, thus relieving them of exercising mental muscle for themselves. They rely on denying anything new is coming along until it already is developed and accepted; then they claim they knew it all along. You'd think them embarrassed over the above; but then, you'd be mistaken. However, the gaussian antenna escapes me ... at least for the present time. But, I don't want the news to filter you!

So I guess it is an absorption phenomenon, rather than resonance. Or, infrared radiation from the maagnetron! ;-) This information, BTW, comes from Ron Schmitt's "Electromagnetics Explained".
