SUPERCAPACITOR CEMENT IS KEY TO BUILDINGS THAT STORE THEIR OWN POWER

Summary from the TLDR Hardware newsletter

Scientists from the Harbin Institute of Technology developed a cement-based supercapacitor capable of powering small devices like LEDs. The device uses a 3D-printed electrode ink made from carbon nanotubes and cement, enabling fast energy discharge. Future research will enhance cold-weather performance, potentially allowing buildings to store energy and support smart environments.
