Almost 200 years after the Carnot limit defined the maximum efficiency of heat engines, scientists have introduced a microscopic design that seems to break the rule.

This clever feedback process allows the engine to convert nearly all absorbed heat into usable work.
The premium segment comprises phones that offer impressive designs, good durability, and capable cameras. While the price tags are higher than those of mid-range devices, these phones typically offer good…
