Abstract: A kitchen ensemble includes one or more appliances and one or/more cabinets. Some or all of the appliances and cabinets have windows made of a material having a controllable opacity. The windows are opaque in the normal state, but can be made transparent by operation of a suitable control. Therefore, one can view the contents of the cabinets and/or appliances without opening any doors. The invention therefore enhances the convenience of using the kitchen, and saves energy by minimizing the number of times a refrigerator or range door is opened. It also enhances the aesthetic qualities of the kitchen.
