Algal Biophotovoltaics for Self-Sustaining Microbial Fuel Cells
Quick fact
Cyanobacteria, also known as blue-green algae, can generate electricity when exposed to light—and some biophotovoltaic devices can power small LED lights for days using just water and sunlight.
Why this is interesting
You've probably seen solar panels, but what if you could use living algae to produce electricity? Imagine a solar cell that also cleans water and needs no external fuel—what if it runs on pond scum?
