No, I don't think so. The stuff pumped out of the supply tank, and into the reactor, is 100% water; air comes into the supply tank at the top and displaces the water in the tank as it's pumped out. The water will have some air dissolved in it, come to think of it. I doubt it's a significant fraction, however, and I doubt it's more than a tiny fraction of the gas coming out. > Harry >
