Now, you go anywhere outside your house, your city or even in jungles you don't have to worry about your electronic devices getting out of power, because now you can recharge your electronic devices with water.It has been possible with Powertrekk by myFC of Stockholm, Sweden.
It is a device that produces power from water. It is a small container made up of metal and plastic that contains a chemical called sodium silicide powder which when mixed with water produces hydrogen gas. This hydrogen gas when gets in contact with oxygen inside the container produces electricity.
This device produces the same amount of power as 4 A size batteries and it can give you about 10 hours of phone battery life. This device should be available by May in REI stores. There is no official announcement about its price but its price should cost between $200 and $250 approx.
It may not be useful for everyone because of its bulky size, but as I have said earlier it is useful for people who spend their time away from electricity and outdoor enthusiasts.
