We use "thermal batteries" in our spare garage fridge as it doesn't have much in it, but filled with water, saves us money on electricity as the water helps the fridge maintain temperature. =)
These 'thermal batteries' are also great if you live in area that experiences power outages: If you have enough insulation and a big enough volume of water you can actually go for days without dropping more than a few degrees. Not really something we want to do with our precious little balls, but a good idea if you are going to be away from home for awhile and you lose power.
I've been thinking about something similar for when I finally buy my own place and have my dedicated snake room....we'll see, but I know of a guy a few hours from me who lost his whole collection while he was away and lost power for a few days.
