The Archdruid Report: Energy Follows Its Bliss

Posted by Carl Jonas in english, news.

Via Chris Tweed, a druid(?!?) explains exergy. Very long post – worth reading the whole thing: "In a very small way, as you sit there considering your cold coffee, you’re facing an energy crisis; the energy resources you have on hand (the remaining heat in the coffee) will not do the work you want them to do (warming your insides). Notice, though, that you’re not suffering from an energy shortage – there’s exactly the same amount of energy in the dining room as there was when the coffee was fresh from the coffeepot. No, what you have is a shortage of the difference between energy concentrations that will allow the energy to do useful work. (The technical term for this is exergy). How do you solve your energy crisis? One way or another, you have to increase the energy concentration in your energy source relative to the room temperature environment."
