Scientists build cooling system that turns waste heat into cold without electricity
SMRTR summary
Researchers in Germany and Japan built the world's first cooling system that runs entirely on waste heat, sunlight, or ambient warmth, with no electricity needed. Two ultra-thin nickel-titanium films work together, one converting heat into mechanical force, the other generating cold, reaching 84% of maximum theoretical cooling efficiency.
