Merging metabolism and power: development of a novel photobioelectric device driven by photosynthesis and respiration.

ABSTRACT: Generation of renewable energy is one of the grand challenges facing our society. We present a new bio-electric technology driven by chemical gradients generated by photosynthesis and respiration. The system does not require pure cultures nor particular species as it works with the core metabolic principles that define phototrophs and heterotrophs. The biology is interfaced with electrochemistry with an alkaline aluminum oxide cell design. In field trials we show the system is robust and can work with an undefined natural microbial community. Power generated is light and photosynthesis dependent. It achieved a peak power output of 33 watts/m(2) electrode. The design is simple, low cost and works with the biological processes driving the system by removing waste products that can impede gro
