In a striking example of ingenuity, Australian inventor Tom Chalko has converted a deep freezer into an incredibly efficient refrigerator.

Most fridges waste at least 30 kwh of energy a month – this usually occurs when the door is opened. Cold air trapped inside is heavier, and falls to the floor as the door is opened, leading to the empty space being filled with warm air. With Chalko’s top-loading device, gravity keeps the cold air inside the fridge, even when the door is kept open.

Compounding these incredible facts, the chest fridge only needs to run for about 90 seconds a day (using 100 watts of power) to maintain normal temperatures. That’s as much power that a 100 w light bulb burns in one hour.
