Concrete buildings could become rechargeable batteries you can live in

Concrete is the most widely consumed material in the world after water. Now, researchers have been exploring how it can be used to store electricity to eventually transform concrete buildings into rechargeable batteries that we live and work in. The engineers from Sweden's Chalmers University of Technology demonstrated a prototype concrete battery that holds 10 times more power than previous approaches, you'd need 200 square meters of concrete batter to "provide about 8 percent of [a typical home's] daily electricity consumption," says researcher Emma Zhang. — Read the rest
