 Texting can Charge Your Phone
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.

A solar panel's power output is dependent on how the environment is - amount of sunlight, temperature and also the resistance of the circuits connected to it.

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.
