DECORATE - AND KEEP WARM

The video discusses a novel approach to central heating using carbon paint developed by the National Coal Board. This paint, made from carbon particles derived from coke, conducts electricity and heats up when an electric current is passed through it. By attaching electrodes to walls, the paint can heat up to 80 degrees centigrade, providing a comforting heat source. Although still experimental, this technology could revolutionize home heating in the future.
