Meet the new fungus battery that needs to be fed instead of charged

In a groundbreaking step toward sustainable technology, scientists in Switzerland have developed a fungus battery. It’s a fully biodegradable, living power source made almost entirely of natural materials. Instead of recharging it with electricity, you give it nutrients and water. And it works.

By 2030, the world is expected to generate 75 million metric tons of electronic waste. Most batteries today contain toxic metals and synthetic components, which are difficult to recycle and harmful to the environment.
