Water-cooling - help please

  1. Jun 8, 2006 #1
    im doing an investigation into what is the most efficient way to cool a glass of water. so far i am looking at:
    -Refrigeration/ Freezing
    -Adding liquid coolants:
    -Distilled water
    -mineral oils

    any more ideas?

    Efficient or fast? They are not the same thing. And you'll need to be more specific about what you are going to do. Ie, the most efficient way to cool a glass of water from boiling to room temp in a room is by letting it cool on its own: you add no additional heat to the room, as you would if you used any sort of active cooling.

    Yeah... for fast, I'd consider dropping it into a vat of liquid nitrogen. Given the energy expended in order to liquify the nitrogen in the first place, however, it's hardly efficient.
