Besides introducing water proof cell phones that allow users to capture photographs underwater, the latest 21st century has also introduced something more innovative and ingenious. Yes, phone charging with water is now possible as this device simply utilizes saltwater and oxygen for converting chemical energy into electricity. Consequently, the produced electricity is then used to juice up your smartphone.
This device has a hollow port which is approximately the size of your smartphone. The card holds saltwater that stirs electricity after inserting the card into the port. There is a cable for connecting your device with the generated electricity.
This device has the potential to generate 1800 milliampere-hours of electricity, sufficient enough for juicing up an iPhone. Moreover, you can also charge your tablet, but you will need two ports for this for charging larger devices. Its optimum usage rate is once, after that its rate declines eventually with frequent usage.
There are two major elements working together during this process which are hydrogen and oxygen within a closed chamber. Hydrogen atoms flow inside the batteries reaching the anode section, resulting in a chemical reaction stripping off the electrons. The released electrons are mainly responsible for the energy required the device for charging.
As soon as the electrons manage to strip themselves off, the electrons turn positive and the hydrogen atoms can flow through the electrolyte.
On the other end called the cathode, oxygen present in the air can combine with hydrogen which flows through the electrolyte. Thus gives birth to a harmless by-product called water.
This device will be available from this year, and each card is going to cost $1.50, according to Mashable.
