The enduring popularity of stainless-steel domestic fridges means they are no longer seen as industrial or retro. However, they still make a bold statement - especially when paired with environmentally friendly technology and features designed for the 21st century. Take GE's side-by-side refrigerator ($12,480), which reduces energy consumption with its adaptive cooling-fan speed: an optical sensor automatically switches the fans to a higher speed during the day when usage is greater, and vice versa at night when the doors are seldom opened. Other good ideas include a door alarm that beeps if either door is left open, a child lock and a sleep mode that renders the refrigerator silent. The product is available at Sogo, Causeway Bay; Chung Yuen, Ocean Centre, Tsim Sha Tsui; and CMK, Times Square, Causeway Bay.
