The LED Solar Pebble is a new multi-functional, solar powered device developed by Plus Minus Solar. The Solar Pebble is a sustainable light source that can be used in developing areas such as Africa. In developed nations, it can function as an eco-friendly charger for smartphones, MP3 players and other mobile devices. The Solar Pebble requires no batteries or electricity and generates its own power from its built-in small solar panel. The production costs of the Solar Pebble are low enough that it could be distributed as a humanitarian product, possibly using profits from its sales in developed countries.
Look for the Solar Pebble release in June of 2010.
