You could make a fridges and ovens with Aerogel insulation, instead of polyurethane and fibreglass respectively, have something thinner walled, or more efficient, and more fireproof into the bargain.
Right now Spacewall and Thermaslim are very expensive and exotic oddities, but at about twice the thermal resistance of polyurethane, and four times that of rockwool, I expect the time will soon come when appliances with panels of such things for insulation are pretty commonplace.
