China just developed a transparent cooling film that can help glass reduce heat without using electricity.
In this video, we break down how researchers led by Professor Zhu Jia created a radiative cooling film that can stay clear like ordinary glass while sending heat directly into space through a narrow infrared window in Earth’s atmosphere.
You’ll learn why traditional window films force a tradeoff between light and heat, why electrochromic glass needs power to work, and how transparent radiative cooling could reduce air conditioning demand in buildings, smartphones, cold-chain logistics, solar applications, and even glacier protection.
We also explain how the material was tested in Ningbo, China, where two identical glass boxes showed a temperature difference of 21.6 degrees Celsius under direct sun, and how building simulations suggest this kind of film could cut annual energy use by up to 20% in hot climates.
This is not just a story about cooler glass. It is a story about air conditioning, smart windows, climate technology, radiative cooling, energy efficiency, building materials, and the future of surfaces that cool themselves without drawing power from the grid.
