Algae powers computer for a year using only light and water

NightAuthor, 10 months ago

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.

No details on what the processor is even doing, only that they technically consider it a “computer”

… and light. This is a solar panel. Cool, but not really ground breaking as the article suggests.

With embedded battery, where neither depend on mined metals, both are biodegradable and non toxic, and it’s carbon fixing (negative greenhouse gas impact). Yeah that’s fucking groundbreaking.

You don’t need a battery, just a capacitor for these levels of power draw, and you would be hard pressed to find a material that is more abundant on earth then silicon.

algae must have finally run out

Sounds very promising could see this for powering IoT devices outside possibly one day.

Small sensors would be an ideal application as well.

Definitely would be small out door temp sensor or weather sensors.
