Wrapping ice and snow to slow/stop melting

Amazing breakthrough technology: cover ice and snow with ‘green’ radiative cooling foil to slow/stop melting and even help freezing

by Jinlei Li et al. 11/02/2022 in Science Advances
Protecting ice from melting under sunlight via radiative cooling: Here, we demonstrate that a hierarchically designed radiative cooling film based on abundant and eco-friendly cellulose acetate molecules versatilely provides effective and passive protection to various forms/scales of ice under sunlight. This work provides inspiration for developing an effective, scalable, and sustainable route for preserving ice and other critical elements of ecosystems.

VC1 Editor’s comment: The cost-effectiveness of this technology remains to be proven in practice. However, the the science appears to be sound, cooling effects of ultra-white paint have been proven in shopping center-scale commercial application, and the acetate film is made from renewable materials and should be safely biodegradable in application.
