Biophotovoltaic (BPV) devices are biological solar cells that generate electricity from the photosynthetic activity of living microorganisms such as algae. When light falls on the algae, a series of reactions take place which split water into protons (hydrogen ions, H+), electrons and oxygen. These are vital ingredients for transforming carbon dioxide and other inorganic materials into things like carbohydrates and proteins which allow the algae to grow. Biophotovoltaic devices exploit this charge separation to generate electrical energy.

So with that in mind lets not forget that our findings submitted to natural England give good evidence that the amount seaweed we find on our shores is due to accelerated growth aided by the chalk reef……seaweed electric anyone?
