    This wouldn’t work.

    Your freezer will dump the heat taken out of the water to produce the ice into the (indoor) air, it also uses electricty to run the freezer, which is also released as heat.

    The “air conditioner” also uses electricty to run, which creates even more heat.

    All of this is a net INCREASE in temperature in your house/boat/office.

    :wacko:

    Depends on the amount of ice.

    Most homes have a freezer that’s left on permanently.  Some have water chillers and ice makers built in too.

    A 1 inch ice cube at 75°F room temperature (24°C) will take 45 to 60 minutes to melt. A standard 1 ounce cube (30 grams) will take 90 to 120 minutes to melt at the same temperature.

    In most situations, ice made in a standard ice tray — those plastic models with space for a dozen tapered cubes — takes about three to four hours to freeze in your home freezer.

    So a pair of standard ice trays will produce enough ice for a 4 litre air cooler for 12 hours if  1/2 of one tray is used.

    But there another way.

    If marble stones were used instead of ice cubes, you’d only have to replace them once a day due to being a metamorphic rock.

    Yes, but they aren’t magical.

    If you put more things into it that it needs to cool, then it will consume more electricity than it did before.

    So a pair of standard ice trays will produce enough ice for a 4 litre air cooler for 12 hours if 1/2 of one tray is used. But there another way. If marble stones were used instead of ice cubes, you’d only have to replace them once a day due to being a metamorphic rock.

    Doesn’t matter if its water or stone, the law of conservation of energy still applies to both. In the case of water the heat is transfered out of the water and into the air, which causes it to freeze. This is then re-absorbed from the air when it later melts.

    However as I already said, the freezer requires energy to transfer heat out of the water/stone into the air, so there is a net increase in energy, which means it will get warmer.

    That’s good news.  I throught all my ice cream cakes running up my electric bill   :yahoo:

    Ge

    I have a perfect solution for you DOA. Buy an inflatable rubber ring, fill it up with water, freeze it, then place the ring over your head onto your shoulders.

     

    And chill.
