Anyone want to test the effect of salting the ice and leaving the freezer unplugged while it melts with the food still inside?
Adding salt to ice allows it to absorb more heat faster, which means that things will freeze when subjected to salted ice... since the food is already frozen, you can rest assured that it will stay frozen for some time as long as the freezer isn't opened frequently, and the salted ice will most likely help to keep it frozen and keep the freezer's internal temp low enough to help keep the food frozen, while the salt melts the ice.
I'm not sure if the ice has to be in somewhat direct contact w/ the food for this to work, though.
It's how you make home-made ice-cream... add cream and sugar to a pail that rotates inside another pail that has ice and road salt in it, and mix the cream and sugar constantly while rotating the pails against each other.
