Bricks have a porous structure that enables the storing process. Those pores are filled with an acid vapor which acts as a dissolved for the iron oxide (or rust) from which bricks are composed. A gas is transferred through the cavities of bricks which are filled with a sulfur-based material that reacts with iron. As a result, a conductive plastic, polymer PEDOT, surrounds the bricks’ porous. “In this work, we have developed a coating of the conducting polymer PEDOT, which is comprised of nanofibers that penetrate the inner porous network of a brick; a polymer coating remains trapped in a brick and serves as an ion sponge that stores and conducts electricity,” Julio M. D’Arcy, co-author of the study and an Assistant Professor of Chemistry at the Washington University in St. Louis, stated.
According to the scientific team, ***************the proposed method could generate substantial amounts of renewable energy.************* Researchers estimated that 50 capacitor bricks would take 13 minutes to charge and could provide enough energy to power the emergency lighting of a building for at least 50 minutes.
