extraction of the uranium content of about a cubic kilometer of seawater per *minute*. I'm not aware of any chemical process -- not even purification of drinking water -- which has ever been done on anything like that scale. The chemical processing proper is done on the saturated adsorber. No, that's the second stage of the chemical processing. The first stage is running seawater through the adsorber. Just because that stage looks simple and easy, doesn't mean that it *is* simple and easy... not when you're trying to process cubic kilometers per minute. has already been tested, in the ocean, and fouling was not a problem. How do you know? It's not mentioned, that I've seen, but that doesn't mean it wasn't a problem. If you want to be concerned about fouling, worry about growth of organisms on the support structure, not the adsorber itself or its cages (if this was what you *were* worrying about, then I agree it would need to be addressed.) I'm concerned about all of the above. :-) They're all potentially serious issues when trying to turn this from a lab-scale demo into a large-scale production process. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |

Bill Higgins wrote: The ace infrastructure people at Fermilab have, during a maintenance shutdown several weeks long, been doing battle with the dreaded zebra mussel. An April report indicated that divers had already removed 8000 pounds of the critters from our water systems... Ah yes, those things. I'm on the Public Advisory Committee of Toronto's main water plant, which draws from intakes offshore in Lake Ontario. A few years back, during a maintenance shutdown, chlorine lines were run out along the intake pipes, so that some chlorine can be injected right at the intakes. This has nothing to do with disinfection, in the public-health sense; it's to keep the damn zebra mussels out of the pipes. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |

Right, that's why we'll eventually use up the oil supply. No, we won't. We will always have oil. We may stop using it, but we'll never run out. Huh? Oil is a finite resource. Since no more of it is being made, no matter what rate we use it at, we will eventually run out of it. |

But if everyone could harness solar and wind energy through a single purchase item, unlike a car that needs gas, or a home that needs electrical power, then the big money boys are out. That demonstrably cannot happen - even at a 100% rate of conversion, not enough wind and sunlight hit, say, an office building, to meet the energy demands of that building. |
