The best solar panels to date are able to convert around 20 percent of sunbeam’s energy into electricity. Which is a massive improvement considering they could only convert 13 percent about ten years ...

Rust is often associated with decay and disrepair, but scientists at Caltech and Northwestern University are looking at rust differently: as a means of generating electricity. Rust, after all, is ...

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 salt ...

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 saltwater, ...

An iron-air battery that stores and releases energy through a reversible rusting process has become the first of its kind to connect with a public electricity grid. On 30 July, the Dutch start-up Ore ...

Researchers have shown that iron oxide layers can convert kinetic energy of saltwater into electrical power. There are many ways to generate electricity -- batteries ...
