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.
Powered a single microchip for six months with the chip just burning cycles for 45 minutes on and 15 minutes off. Further details not provided in article. Probably in the paper if you wanna read that.
Abstract said it powered an Arm Cortex-M0+. The Arm Cortex-M0+ processor is the most energy-efficient Arm processor available for constrained embedded applications..
Buried all the way down in the abstract, damn. Glad I didn’t go seeking this info myself, would have wasted a lot of time reading that paragraph.
I tried a quick google to see how much it uses but I guess it depends on peripherals.
Still cool
Agreed
