Fridge hack - How to create a fridge which consumes only 0,1 KWh per day?

Hungarian version.

I have found an interesting webpage. Here. The fridges these days if they have a consumption rating of A+, consume around 0,7 Kwh/day. Why is the design of today's fridges wrong? As we open the fridge door, all of the cold air spills out of it, because of the physical laws. So the air inside needs to be cooled down again and again after each door opening. This requires lots of energy. However there are chest freezers which have a door what opens upwards not to the front. This is a great idea! In this way the cold air does not spill out and the freezers are better insulated as well. The freezer should be modified in a way that it would cool the inside air to 41 degrees Fahrenheit instead of -0.4 degrees Fahrenheit. So we would have a freezer which has a door opening upwards, the cool air does not spill out with a door opening and it is very well insulated. Well, here comes the hack. You can buy on E-bay a digital thermostat for 10 dollars including shipping. Our job is only to change the fridge previous thermostat to the digital one. In this way we can set a temperature when the compressor should turn on and when to turn off. It is a brilliant and yet simple idea! There is unfortunately a downside. A chest freezer is harder to fill with
food than a standing fridge. And it is harder to get things out of it. But, no pain, no gain. I think I will hack one freezer if I will have the chance. I encourage everyone who likes to tinker with thing to try this out. The site what I have linked says that with the modification the freezer's power consumption went down to 0,1KWh. I do not know if this can be achieved, but if the consumption would be cut in half, it would completely worth it!
