Water and salt: all you need to charge your smartphone

Can you imagine charging your cell phone with water and salt? This will soon be possible thanks to Hydra-Light, a revolutionary technology that has popped up on Kickstarter.

This technology involves a patent that gets rid of battery use. This invention has a carbon battery and a metal cylinder called the “PowerRod.” To use it, all you have to do is take out the PowerRod and fill the battery casing with salt water, or regular water with cooking salt.

The PowerRod’s contact with salt water generates electricity, which can help power a light or charge any device with USB, including your phone.

Hydra-Light has several formats (lanterns, street lamps, batteries) that can be fitted to your needs.

This invention is revolutionary for a few reasons: for one, it encourages the use of sustainable energy and also, it could be a life-saver in moments when other sources of electricity are scarce. Imagine how useful it would be for those who go hiking in the mountains for days.

If you’re interested in getting a Hydra-Light (starting from $38) or you want to know more about the project, you can go to the Kickstarter page, where it’s already received the necessary backing to become a reality.
