Photosynthetic power: a reliable and renewable biological photovoltaic cell

This system, containing blue-green algae, powered a microprocessor continuously for a year using only ambient light and water. Credit: Paolo Bombelli Algae-powered computing Scientists have used a widespread species of blue-green algae to power a microprocessor continuously for a year — and more — using only ambient light and water. Their system has the potential …
