7/25    It's been pretty hot lately and I had this crazy idea to make a
        living quarter cooler without using a lot of electricity. Some
        properties have fountains or swimming pools. How about repiping them
        with a pump so that they'd flow from the roof (like a building
        that is always being rained on) to cool the entire building?
        It'll use some water, but I'm sure it's a lot cheaper than AC.
        \_ A good idea, and not a new one.
           \_ URL please?
              \_ Google for "swamp cooler"
              \_ Google^H^H^H^H^H^HYahoo! for "swamp cooler"
                 \_ How the hell do you feel cool when you're swamped with
                    high humidity? It's just oxymoron.
        \_ The best system is probably very good insulation, reflective/white
           buildings with control of indoor sunshine, opening up to cool
           at night, and possibly some floor-based cooling.
           \_ Most ordinary houses have windows that can be opened to cool at
              night before you go to sleep.  I do that to keep my house not
              as hot during daytime for my parent.
        \_ I have another idea.  Buy a lot of blue ice, or fill up a lot of
           used bottles with water or whatever that has a high specific heat
           capacity.  Put them on a big cart.  Push it out to the backyard in
           the evening.  Push it back indoor in the morning and blow on it with
           a small fan.  It won't work as well as AC, but it's more
           enviromentally friendly and costs less.  If using bottles, lots of
           small bottles will work better than big 5-gallon ones.
