Motorless solid-state cooler uses heat to cool itself; could recycle processor heat into cooling — shape-memory alloy films could turn data center exhaust into refrigeration

Two ultrathin films turn low-grade heat into cooling without an electric motor

Refrigerators, air-conditioning systems and data centers consume enormous amounts of electricity, and cooling demand is constantly rising. A research team from the Karlsruhe Institute of Technology (KIT) and the…
