Conventional cooling systems are often bulky, energy intensive and reliant on chemical refrigerants harmful to the environment. Thermoelectric refrigeration, a potential solution, cools by using electrons to move heat through specialized semiconductor materials, eliminating the need for moving parts or harmful chemicals, making these next-generation refrigerators quiet, compact, reliable and sustainable.
