A multinational workforce of researchers have managed to extract helpful, photosynthesis-based vitality from an algae-powered system, opening up the door for actually sustainable edge computing. The system, comparable in measurement to an AA battery, was used to constantly energy an Arm-based Cortex M0+ (the identical CPU as within the Raspberry Pi Pico) check board for over a yr with nothing greater than ambient mild in a home surroundings. It is being hailed as a possible enabler for future scaling of IoT (Web of Issues) gadgets.

The system was constructed round a typical species of blue-green algae, Synechocystis, that are able to photosynthesizing their very own vitamins from ambient lighting – while producing a minute-but-significant-enough electrical present that is confirmed steady all through a one-year-plus operation (and counting). It is primarily a “set-it-and-forget-it system – as long as there’s ample ambient lighting to offer the algae with sustenance.
