electricity. The Bio Robot refrigerator works by cooling a biopolymer gel via luminescence. Food gets loaded into the gel, and the surface tension of the gel creates an individual pod for each piece added, meaning that nothing is touching anything else, and no odors transfer. The refrigerator itself would take up a lot less space than current models, and could apparently be stored horizontally, vertically, or in zero gravity conditions! So how close to reality is this thing? Sadly, probably not very. Hit up the source for more images of this kitchen beauty.
