From a concept kitchen developed by IKEA, IDEO, and design students from Lund University and Eindhoven University of Technology.
While we often see smart refrigerators as in concept kitchens, IKEA and the designer believe that fridges will become obsolete in the future due to their energy inefficiency. Rather, people will store food much as how they have done so in the past—using materials that are naturally insular, such as cooling ceramic, to keep items as fresh as possible. People will no longer buy groceries on a weekly basis, but with automatic delivery from drones and the like, fresh food will be just as easy to get on demand.
