Elephant Skin Inspires Building Cooling
A team of researchers has developed cement tiles inspired by elephant skin, capable of cooling buildings for up to 20 hours without the need for electricity or fans. The technology leverages a network of cracks in the surface that retain water and slow its evaporation, naturally helping to lower the surface temperature. Experiments have shown that temperatures beneath these tiles remain around 32°C, compared to 42°C under cracked plaster and over 52°C under uncracked plaster. The tiles are made from Portland cement and diatomaceous earth, making them easy to apply on a wide scale. This innovation contributes to reducing energy consumption in buildings, especially as global temperatures rise. Future developments may include integrating the tiles with smart systems that can anticipate weather conditions to ensure even more efficient cooling.
