Electricity made by using seawater

Researchers have developed a low-cost system to generate electricity from seawater, offering a new approach to handle short spikes in power demand. According to researchers from East China Normal University in Shanghai, Shanghai University and the Chinese Research Academy of Environmental Sciences in Beijing, the key to the new generator is an open framework structure with cyanide ions and iron ions which can easily accept and release electrons. When combined with a metal anode, the structure can be used to generate electricity from seawater.
