Rethinking refrigeration

Imagine if we changed the designs of all the refrigerators in the world to be chest fridges? 

Cold air is heavier than warm air and thanks to gravity, this means it falls. Our current models of refrigerators feature doors that are vertical. Guess what happens every time we open the fridge door? Cold air rushes away from our food and free falls to the ground.

Think how much energy was spent cooling that air that just escaped to chill our feet. 

Chest freezers are a box with the door on top. So when the door is open, the cold air stays in the box. Keeping the food cold and our feet warm. 

Learning from nature can help us with efficient product design.
