I think the GP was making a joke. What they suggested strongly implies the existence of perpetual motion machines, contradicting the laws of thermodynamics.

- marcosdumay 7y agoIndeed he is. I'll just post here that it does not violate the second law of thermodynamics. It is a completely real phenomenon that one can verify at home with the ion exchange membranes used to make batteries. (Get some aluminum electrodes, on the scheme salty-fresh-salty water, and add some aluminum hydroxide on the negative side, so you'll have a neutral oxidation and reduction of aluminum on both sides.) What those people created was just an incredibly better ion exchange membrane.
