O3 will remain dissolved in room temp water for a few minutes and in ice cold water for about 20 minutes. Ozone can be generated using dry air quite acceptably, without the generation of the nitric acid contaminant that would accompany 'wet' air."
".....Again this is not so, as far as I know. Some elements or compounds (silicon dioxide, aluminium oxide) will accept energy of some wavelength and then radiate it at another, in the far infrared in this case. All that is required is the conservation of energy. While the same energy is output (more or less) FIR radiation is much more efficient at heating our bodies as it is able to penetrate deeply (unlike radiation of shorter wavelength) and is similar to the resonant frequency of water and tissue and thus the energy is absorbed more efficiently." I will concede your point on the lifetime of O3 in water, Ivan. But does it enter and exist inside the human body as O3? On the matter of FIR - no. Conservation of energy - the first law of thermodynamics - is not sufficient; there is the second law to contend with as well. If any (passive) material could selectively radiate a frequency spectrum different from that of a surrounding environment at the same temperature as the material, one could construct a method of extracting heat defying the second law. This restriction does not apply when the material is held at a different temperature - emissivity of the material then dictates a different spectrum from some other material. This may seem contradictory but it's not - check any good textbook on thermodynamics.I believe it all gets back to the power of advertizing hype - if you believe something works, in a sense it does, regardless of the facts. regards, Kevin Nolan
