Potable Water - The Third Way.

What Brian left to the reader's imagination, is that the head space of the tubes is at a near perfect vacuum, flooded only with water vapor. You might recall that a perfect vacuum will lift a column of water about 32 feet, on a high pressure day. Or had you not figured that out? Well no, he obviously hadn't figured that out. Nor can anybody figure out what is going to hold a column of water 40 ft high as was stated in the original post. The tubes may be 40 feet but the column of water will be considerably less. How much less will depend on how much energy is heating on the hot side and how much energy is cooling on the cool side. The total amount of energy needed is not going to be any different than any other distilling method. Unless you have the free or cheap sources of cooling and heating at specific temperatures this isn't going to work any better either. -jim Well, at least this respondent Jim, is operating at shall we say the 7th grade level of science/engineering insight. Like so many other products of the domestic school system, he seems to have a severe case of self-esteem syndrome. Still, he may be retrievable, starting with a science demonstration he may have missed. Place a beaker of water in a bell-jar and pump the air out. When 99% of the air has been pumped out, the water in the beaker is boiling vigorously, until, in the usual way, the beaker boils dry. The beaker feels cool to the touch, naturally. To quote him: "unless I have a cheap source of heating this won't work..." For the $64 prize: NOW do you get it? Brian Whatcott Altus OK |
