Saline energy solution? Salt water and rust can generate electricity – study


30 Jul, 2019

Rust can generate electricity when salt water flows over thin films of it, exciting new research has revealed, a result which holds potential for inventive new forms of sustainable power production.

Metal compounds and salt water often generate electricity, usually the result of a chemical reaction that changes at least one of the compounds into new compounds. Now scientists at Caltech and Northwestern University have found that rust, or iron oxide, converts the kinetic energy of flowing salt water into electricity.
