New Rechargeable Battery Uses Water

Posted by samzenpus on from the I-want-my-water-engine dept.

fergus07 writes "Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new 'mixing entropy' battery alternately immerses its electrodes in river water and sea water to produce the electrical power."

    Environmentalists have a bad name because the industries that are doing all the damage find character assassination easier than actually cleaning up their mess. And much of the anti-environmentalist movement is made up of people that believe that God would never allow for more flooding because the Bible doesn't say anything about another great flood. Or are so self centered as to think that they don't have any sort of social responsibility for the next several generations.
