Saline Energy Solution? Salt Water and Rust Can Generate Electricity Study


Published time: 30 Jul, 2019 14:59

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.

“A similar effect has been seen in some other materials. You can take a drop of salt water and drag it across graphene and see some electricity generated,” Caltech professor Tom Miller said, explaining that while graphene films are difficult to fabricate and scale up, iron oxide is “basically just rust on iron, so it’s pretty easy to make in large areas.”

The team used physical vapor deposition (PVD), which turns normally solid materials into a vapor that condenses on a desired surface, to ensure that the rust formed in a consistent, thin layer. Incredibly, they were able to create a layer so fine that it’s around 10,000 times thinner than a human hair.

When salt water solutions flowed over this layer, the ions in the water attracted electrons in the iron under the layer of rust and dragged those electrons along with them, generating an electrical current. The process could be used in the future to generate energy on items like buoys floating in the ocean.

4. They actually think there maybe...

"The process could be used in the future to generate energy on items like buoys floating in the ocean. "

Now go tune-up your "buggy whip"...

5. Many here do not give a flying fuck about any innovation

they try to fit every single post into their broken "Lefty vs Righty" bullshite "ideology"

Posting here is a lot of work for ~25-30 views (actually probably more like 10-15 unique IP's, considering re-loads lol)

You're talking to a bunch of dinosaurs - many don't even believe solar / wind works. Even in 2019, when these renewable energies are in the global news every few days, setting records.

9. A lot of things are possible at that level, powering buoys with rust and salt water, meh...
