This swamp thing is nothing to fear.

University of Cambridge scientists have designed a way to create electricity out of pond scum — which they believe could be a far more “practical” solution to powering small devices than conventional and rechargeable lithium-ion batteries.

Their lean, green technology, which is about the size of a AA battery, was enough to power a low-energy computer chip that’s found in tens of billions of small devices across the globe.

As reported by The Verge, it would take about 333 million algae “batteries” to run an average desktop computer.

Constructed out of cheap and largely recyclable materials, the easily replicable technology could be used to power the so-called “Internet of Things,” a vast global network of small devices exchanging data in real-time.
