Tag: Walls Become Power Plants

By Futurist Thomas Frey

Imagine driving past a building and not just seeing its windows, doors, and facade—but glimpsing the stored energy humming inside its very walls. In a radical shift from mere structure to energy infrastructure, MIT researchers have developed a new form of concrete—electron-conducting carbon concrete (ec³)—that stores and discharges electricity, elevating walls, sidewalks, and foundations into living batteries. Their latest prototype improves energy density ten-fold over prior versions.

This is more than a clever trick. It’s a tectonic redefinition of how we build, live, and power the future.
