Defrosting a freezer with an improvised water collection method In refrigerators , defrosting (or thawing ) is the removal of frost and ice . A defrosting procedure is generally performed periodically on refrigerators and freezers to maintain their operating efficiency.
A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.

So, if the turkey weighs 12 pounds, plan for it to defrost in the fridge for about three days. If 16 pounds or more, make sure it's placed in the fridge four to five days before the holiday arrives.
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
How long will my food last during a power outage? According to foodsafety.gov and the U.S. Department of Agriculture , your refrigerator will keep food safe for up to four hours during a power outage.
