Thermodynamics

Metals that conduct electricity also produce heat, right? Well, no, not all of them, according to recent research led by Berkeley Lab. They've found one type of metal that keeps its cool as electrical current moves through it, and may lead to a range of new and super-efficient electrical devices.

A revolutionary new type of smart window could cut window-cleaning costs in tall buildings while reducing heating bills and boosting worker productivity. Partially inspired by the reflective properties of moth eyes, this smart window is said to be self-cleaning, energy-saving, and anti-glare.
