Sharp has been created on Solar Mobile Phone.  This is the 1st solar mobile phone in the world. With built in solar panel, it’s allowed users to charge the phone with solar source.  Users can use the phone (Talking) up to 2 hours with only left the phone with in 10 minutes under the sun.

A small animation on the phone screen help users to know the battery is fully charge if left more duration under the sun. Really practical while no any electricity source around you. The water proof solar panel is also usefull while in the rain. Maybe you left the phone outside. When rain is coming down, the waterproof solar panel is still keep the phones enable to use.  But it only realease at Japan by this year. I hope it will be distributed around the world next year.
