Charge Your Mobile Phone With Water!!

Sweden’s KTH Royal Institute of Technology ~ the researchers finally found a way to charge the phones anywhere without electricity, provided there is a water source nearby.

It’s the world’s first water-activated charging device that powers using fresh or salt water, the developers claimed. It can extend battery life up to 3 watts.


How much Water is needed?

Not much Consumption of Water is needed. Only one tablespoon of water is enough. So if you take an iPhone, the charge would be enough for between 25 and 100 per cent of its battery capacity.

It’s Importance


Handy for anyone who spends time away from electricity, the small, lightweight PowerTrekk could power critical devices for warfighters and aid workers deployed to remote areas of the world. Even in a desert, a spoonful of water from your thermos can give you power.


How is it Possible?

To use the PowerTrekk charger, you

~fill-up water compartment with about one tablespoon,

~close the lid 

~connect it to the electronic device with a USB cable.

It starts charging automatically as the water inside interacts with a small disposable metal disc causing hydrogen gas to be released. 

When the gas combines with oxygen it converts chemical energy into electrical energy. While in many ways fuel cells are similar to batteries, they are different in that electrodes do not become consumed making them finite. 

Instead provided water and air is provided to the electrodes, these fuel cells will run.

This sounds interesting, we eagerly wait for this to be in our hands. It would probably save our electricity.

Moreover this is totally ecofriendly as water vapours is the only byproduct.
