A battery-like device that runs on algae, light, and water can power a microprocessor chip—the brains of a computer—for up to a year, researchers report in a new study. About the size of a AA battery, the new device is built using “common, durable, inexpensive and largely recyclable materials,” they write.It also does not need to be recharged like a conventional battery would. As long as the sun is shining, the algae soak it up and produce electricity.
No details on what the processor is even doing, only that they technically consider it a “computer”
