Scientists Successfully Generate Electricity Using Freshwater and Saltwater

By simply utilizing what nature has to offer in terms of water, scientists from Stanford University have developed an effective way to generate electricity naturally and without causing pollution. Yi Cui, associate professor of materials science and engineering at Stanford, and his colleagues have developed a system that generates electricity using electrodes and a combination of freshwater and saltwater -- and nothing more.

The process involves the utilization of ions found naturally in saltwater, as well as those generated by electrodes submerged in water. A positive and negative electrode pair are first used to charge freshwater with ions, which is then drained and replaced with saltwater. The saltwater, which is naturally up to 100 times more ionic than the freshwater, increases the voltage causes a net gain in electricity. This electricity is then captured and stored in large batteries.'
