Poor Singapore, chewing gum is banned in that country so I suppose they may never get to experience the Chewing Gum Battery Concept! It is a simple and innovative idea where paper battery is kept charged at a solar empowered dispensing station, and can be easily used for gadgets whose battery dies out unexpectedly. I suppose it is intended for tourist places or maybe college campus, but it sure is a neat way to get instant power.
Chewing Gum Battery is a 2012 iF Design Talents entry.
