With This Paint, Your Walls Can Generate Power

The walls of your home could soon produce electricity, thanks to a new thermoelectric plant which captures the waste heat from hot surfaces and converts it into electrical energy, scientists say. Scientists expect that the thermoelectric painting technique can be applied to waste heat recovery from large-scale heat recovery from large-scale heat source surfaces. For example, the temperature of a building’s roof and walls increases to more than 50°C in the summer.
