57: Sang Han - How can a roof stay cool in the New Mexico sun?

Nanovation

Sang Han from the University of New Mexico has spent his career developing advanced electronic and photonic materials. In this episode of the Nanovation podcast, Sang and Mike discuss radiative cooling technology, which promises to cool surfaces, such as the exteriors of homes and buildings, even in direct sunlight. They talk about the physics of radiative cooling, different methods for its implementation, and the challenge of developing a manufacturing process suitable for coating entire cities. A potpourri of related topics come up along the way, including the ups and downs of global technology competition, how to incentivize innovation in manufacturing, and the excitement and challenge of starting a company.
