Rust, after all, is nothing more than iron oxide. Thin films of it, as the scientists show in a new study, could be used to generate electricity when interacting with salt water.

Scientists at Caltech and Northwestern University developed a thin film of iron oxide – rust – to create a new efficient electricity generating method.

An iron-air battery in the Netherlands, which can store energy for 100 hours or more to make renewable power sources more consistent, has become the world’s first “rust” battery to connect ...

It's not unusual to find rust around salt water, but now the pairing might actually be useful. Researchers at Caltech and Northwestern University have found that electricity can be produced when ...

And now there's rust. New research conducted by scientists at Caltech and Northwestern University shows that thin films of rust -- iron oxide -- can generate electricity when saltwater flows over ...

Flowing saltwater over rusty metal can create usable electricity. Rust is a common problem on bridges, cars, and other metal structures, but new research shows that when it’s combined with ...

Researchers have developed a new way to generate electricity by moving saltwater across thin films of iron oxide, or rust.
