MIT built a three-layer passive cooling panel of aerogel, hydrogel and reflective material; tests cooled it 9.3°C below ambient and suggested up to 40% longer food storage in humid conditions

Researchers have created a passive cooling system that uses natural processes. This innovative device cools significantly below ambient air temperatures without electricity. The system can extend the shelf life of perishable foods, especially in humid conditions. Space cooling demand is rapidly increasing globally, straining power grids. This technology offers a promising solution for off-grid cooling needs.
