An international team of scientists, led by King’s College London, have developed a thermogalvanic brick that generates electricity as long as the two faces of the brick are at different temperatures. This is due to balanced ‘electrochemical’ reduction and oxidation processes occurring inside the brick at the two faces.

As long as electrodes at these faces are at different temperatures, the electrochemical reactions occur and electricity is generated. The compounds inside are not consumed, do not run out and can never be overcharged. As long as there is a temperature difference there can be electricity. For example, if a house or shelter’s outside wall is sunny and hot, but the interior shaded and cool, electricity can be produced by the wall.
