Wat-er good idea for charging phones
Date published: 25 January 2015
Tap water
We could all soon be charging our phones, tablets even car batteries with tap water within a few years.
A Japanese company has invented a new type of rechargeable battery that can be charged by topping it up with water.
Old batteries are huge air polluters, and so development firm Fuji Pigment have produced a new device that is renewable and clean.
The new battery called the 'aluminium-air' is quicker to charge and has a bigger capacity, so it lasts longer. It can be charged with tap water or salt water.
Water supplier United Utilities admitted: “We’ve never heard of tap water being used like this before.”
