It is now possible to charge your phone's battery without the use of power resources. It can be charged just by sending a text message.
A company head quartered in London called, Buffalo Grid, has introduced a solar-power cell phone charging station. To make use of the energy of this station, all that needs to be done is to send a text message from the mobile phone.
Using a technique called maximum power point tracking (MPPT), the battery is able to extract power from the solar panel. A battery is charged by a 60-watt solar panel.
MPPT tracks the conditions and alters the resistance to make sure the power output is maximum at any given time.
When a customer sends a text message, an Led above a socket on the battery lights up showing that it is in ready mode for the phone to be charged.
Each text message enables 1.5 hours of charge on a phone. A complete charged phone from Buffalo Grid unit can last till three days.
