Charge Your Phone's Battery by Sending an SMS

I have seen mobile batteries being charged by a charger or wireless charging like that of Nokia Lumia 920 but this is a totally a new concept where your Phone's battery gets charged up by just sending a "SMS". Buffalo Grid has developed a solar-powered cellphone charging station that gets activated by an SMS. The system can be beneficial for people living off-grid as recharging their phone is now an SMS away.
