Red Bricks as New Battery/Super Capacitors (yes, those red bricks used in construction)
Designers and engineers have previously recognized the brick's ability to absorb and store the sun's energy, but the latest study marks the first time researchers have developed a strategy for converting a red brick into a supercapacitor.
"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," D'Arcy said.
The iron oxide, or rust, that give bricks their red color works to trigger the polymerization process. Authors of the proof-of-concept paper have yet to build a chargeable brick, but their calculations suggest a smart brick could store significantly amounts of energy.
