@thebrainmaze: Cooling Food with Clay and Water - This electricity-free refrigerator uses two clay pots with wet sand packed between them. Water slowly evaporates through the porous outer pot, absorbing heat and cooling the inner chamber. A damp cloth traps the cool air, helping fruits and vegetables stay fresh longer in hot, dry regions.
