Energy efficient refrigeration

This article describes a household refrigerator that requires about 0.1 kWh per day to operate. The refrigerator offers excellent food-preserving performance, because temperature fluctuations in its interior are naturally minimized during everyday use. This fridge is 10 to 20 times more energy efficient than typical household fridges on the market today. It seems that the biggest obstacles in increasing the energy efficiency and food preserving performance of household refrigerators are strange human habits and lack of understanding of Nature, not technology or cost.

Comparing the daily energy consumption of various refrigeration devices available on the market reveals that well-designed chest freezers consume less electricity per day than refrigerators of comparable volume, even though freezers maintain much larger interior-exterior temperature difference…
