    Here's a nice cheap low tech alternative that you can use to keep your tank temperature stable when the power cuts.

    Nifty self-heating hot packs ;)

    [​IMG]

    Below you can see the small metal disc inside the liquid pack. Flex it a few times and it starts off a reaction. Crystals are formed and it stays hot for 2 hours (too hot to hold comfortably in your hand - when used therapeutically one would place it in a towel else you'll burn yourself!).

    [​IMG]

    Once done with it you place it into boiling water, the crystals will desolve and once cooled its ready to use again. Can be reused hundreds of times.

    These are available in bulk for the chaps fortunate enough to have big reefs.

    That is an absolutely fantastic alternative for warmth.I wonder if they are ever going to make one for cooling?:p..In my line of work,we test for acetylene accumulating in the oxygen plants.One of the chemicals used for the test turns the glass beaker cold when mixed(that way you know the chemicals were mixed properly......I wonder if they have not created something based on that principal for cooling:)
