Uh oh! Is it time for a new refrigerator?

From the beginning, humans have tried to find ways to keep food, which was difficult to come by, fresh for longer periods. From using ice cold streams to cool dark caves to hiring runners to relay snow down the mountains to cool the drinks of rich nobles, to packing ice blocks in straw over the winter, people have tried just about everything to preserve their food.

From the powerless ice box through Thomas Edison’s lab, innovation led to the electric refrigerator then the frost-free freezer to new more energy efficient foams and better coolants to the newest possibility ~ magnetic refrigerators. Each generation has looked for new ways to advance the preservation of food ~ as well as a place to hang their children’s drawings.

Over the next few posts, let's look at the options.
