However, an experiment by Teng Li and Liangbing Hu of the University of Maryland may soon put it there. For Dr Li and Dr Hu, writing in Nano Letters, have just described how wood might be used to make one class of batteries cheaper by permitting the lithium now employed in them to be replaced with sodium. Their work might lead to is giant sodium-ion batteries for the overnight storage of electricity from solar power stations. Cheap storage is the missing part of the solar-energy jigsaw--for solar cells themselves are now cheap enough to compete with fossil fuels, in sunny climes at least. The search for solutions to the solar-energy problem has concentrated on making man-made materials more and more sophisticated. It would be a delicious irony if the jigsaw was completed not by one of these snazzy new substances but by one of the oldest materials around.
