Scientists Have Created The Smallest Thermoelectric “Refrigerator”(100 nm Thick), Which Works On The Concept Of Refrigerators Used To Cool, E.G., Electronic Devices. Researchers Hope By Studying This Tiny Device, They May Better Optimize Thermoelectric Devices On Larger Scales To Generate Enough Electricity Or Cool Longer.
