World's Smallest Nano-fridge is So Tiny That it is Invisible Without an Electron Microscope

Scientists have managed to create the world's smallest nano-fridge. However, as of now, they aren’t your regular refrigerators to store eggs and milk.

These tiny devices are a prototype to cool computers and thermoregulate fiber-optic networks. A similar device has been powering NASA’s Voyager spacecraft for four decades. When supplied with electric current on one side, the two sides become hot and cold respectively. This phenomenon can then be used as a refrigerator.
