Living cement charge your phone ? The Doctor Who episode writes itself.

By embedding living bacteria into the world’s most common building material, the team has created a supercapacitor capable of storing electricity. The proof-of-concept material not only holds energy but can also recover its performance when “fed” with nutrients.

Once inside the cement, the microbes create a network of charge carriers that store and release energy.

Early tests suggest the approach already outperforms traditional cement-based storage devices. Even more striking, the cement continues to function after the microbes die, and researchers can bring it back to life with nutrients.

The researchers also tested the cement under extreme conditions. It stored and discharged power in both freezing and hot environments. Six blocks wired together produced enough electricity to light an LED bulb... even modest performance could have an impact. A room made of the material could store around 10 kWh, enough to power a standard enterprise server for a day.

Sounds like quite a leap, but then I guess they don't say how large a block is.

Living cement stores energy and restores capacity when fed nutrients

Scientists turn cement into an energy-storing material using bacteria, offering recoverable power storage for future infrastructure.
