New algae fuel cell design ramps up the efficiency

We could learn a lot about energy production from plants, who have been tirelessly turning water and sunlight into energy for millions of years. Recently engineers have mimicked photosynthesis with devices like artificial leaves, or harnessed it with fuel cells powered by algae. Now, a University of Cambridge team has developed a new design for the latter, which is apparently five times more efficient than existing devices, and much cheaper to make and easier to use.
