sharp has created the first mobile phone with a built-in solar panel. the device is a clam-shell style phone
that yields one minute of  talk time or  two hours of standby with 10 minutes under the sun. if left outside
long enough, the battery can be fully replenished. a small animation on the phone’s screen tells users how
full the battery is. users also don’t have to worry about leaving their phone outside in the rain, since the
design of the case makes it waterproof. by having the built-in solar panels, the phone allows users to
charge up on the go and is also a greener option since the energy isn’t coming from an outlet.the phone
was only released in japan this year, but the built-in solar panel design may be coming to a device near you.
