UCLA scientists have developed a way to utilize a new pollution-free source of electricity: the night sky. Aaswath Raman, assistant professor of materials science and engineering at the UCLA Samueli School of Engineering, and colleagues have used the phenomenon of “radiative cooling” to design a device that can harness nighttime cooling to generate power.
Currently, the device is too expensive and is not effective enough to compete with existing forms of clean energy. However, as the climate crisis increases global temperatures, scientists hope to harness radiative cooling to someday offer a feasible renewable energy source.
