This Computer Ran on Algae for Six Months!

The video discusses a research paper from the University of Cambridge on a photosynthesis-powered battery capable of running a microprocessor. The battery uses microorganisms to generate power, avoiding toxic materials found in traditional batteries. The experiment demonstrated continuous power for over six months using an ARM Cortex M0 Plus. The battery operates in two modes: electrochemical and bioelectrochemical. While not yet practical for high-power devices, this concept could address environmental issues like algae overpopulation.

How did the researchers demonstrate that the battery could power a computer system?

What potential environmental benefits could arise from using algae batteries as suggested in the text?
