Consider this: A refrigerator with separate compartments for food items, and which only cools those sections containing food. It has the potential to be a serious energy saver!
According to Massey University, "The wall uses a motor in its back to act like a piston to send vibrations that resonate through the inner chamber to create cold air, Mr de la Roche says."
As CNet notes, "Concept products such as the Impress refrigerator by Massey University industrial design student Ben de la Roche of New Zealand could influence the way future iceboxes keep food and drinks cool."
The design is one of the 10 finalists for the 2012 Electrolux Design Lab which will be judged in Milan, Italy on October 25.
