It’s a common practice around the world. You open the fridge and then just stand looking at all of your choices. Problem is you are wasting electricity and letting the cold out. The Window Fridge is a concept that eliminates the need to open the fridge, by providing a window.
That helps save the environment while you ponder whether you would like a Coke, Pepsi or Dr. Pepper. The fridge has a tube design that makes it easy to open the panel and spy on all of your food inside.
