When Harvard Professor of Energy Daniel G. Nocera announced he was working with bacteria last year, other scientists cautioned it would be difficult to achieve a productive level of efficiency. At the time, Nocera was aiming for 5 percent efficiency—about 5 times better than plants. This month at the University of Chicago, he announced his bug converts sunlight ten times more efficiently than plants. This increase in efficiency is presumably the novel part of Nocera's latest announcement and upcoming paper.
