Here's an interesting twist on the traditional refrigerator: the stackable Flatshare Fridges. Designed for people who share their fridge with others, it splits the fridge up into various compartments, each with their own door. This saves energy by not letting out as much cool air whenever the door is opened, and it also keeps your food from getting mixed up with everyone else's.
It's certainly not a design for everyone, but I think it could definitely work well in certain situations. What do you think, would segmenting your fridge make your life a little easier?
