materialsscienceandengineering: 3D-Printed “Nano-Skyscrapers” Help Bacteria Convert Sunlight Into ElectricityResearchers have made tiny ‘skyscrapers’ for communities of bacteria, helping them to generate electricity from just sunlight and water.The researchers, from the University of Cambridge, used 3D printing to create grids of high-rise ‘nano-housing’ where sun-loving bacteria can grow quickly. The researchers were then able to extract the bacteria’s waste electrons, left over from photosynthesis, which could be used to power small electronics.Other research teams have extracted energy from photosynthetic bacteria, but the Cambridge researchers have found that providing them with the right kind of home increases the amount of energy they can extract by over an order of magnitude. The approach is competitive against traditional methods of renewable bioenergy generation and has already reached solar conversion efficiencies that can outcompete many current methods of biofuel generation.Read more. #wish they said what materials they use instead of just saying metallic oxides#it does mention that one of the things they’re trying to overcome is the mining that current solar tech needs#so encouraging? ( @oma-goodness)Looks like the metal oxide is indium tin oxide. -- source link
