Well, global warming is a big problem, but a bigger problem is charging your phone again and again to keep it alive. Even if you are busy with a formal business meeting or you are on a trip with your friends, there is one thing which will keep bugging you and that is your phone and its discharged battery.
What if there was some permanent solution to it! May be there is. Some amazing people have come up with an idea which enables us to charge our phones with our own urine and a pair of socks.
Amazing, isn't it?
In a recent trial, a pair of socks fuelled with urine pumped by the wearer's footsteps has successfully powered a wireless transmitter to send a signal to the computer.
This breakthrough has led scientist to believe that the socks-urine combination can one day be used to charge phones and other devices too.
Socks are embedded with miniaturised microbial fuel cells. The 24 individual soft MFC's inside the socks were fuelled with fresh urine which was circulated around by the human operator walking.
This amazing experiment definitely gives us a ray of hope. Just imagine, charging your phone on the go!
