Solar-Powered Purse

This solar-powered purse, designed by a student from Brunel University, promises to make finding keys and other items at the bottom of a bag easier. Dubbed the Sun Trap, the purse has a solar cell on the outside of the bag. The energy is stored in an internal battery which lights up the lining. The lining is made from an electroluminescent material and is lit up by the bag's zip which acts as a switch. The bag goes dark when the zip is closed or after 15 seconds if it is accidentally left open. The purse could also be used as an emergency charger for mobile phones and other wireless devices. :: BBC News via The Greener Side
