Nature : Francois Béguin of the CNRS Research Centre on Divided Matter in Orléans, France, and his co-workers say that seaweed, when burned to a charcoal-like form, is just the right stuff for making the electrodes in state-of-the-art supercapacitors. The seaweed carbon performs as well as more expensive commercial devices, and can hold a charge twice as high without breaking down. They hold up well over time, too: their charge-storage capacity declines by only 15% after 10,000 cycles of charging and discharging. Nature
