The batteries we would buy in Kiribati worked, so that wasn't necessarily the root of my lighting problem, but the lifespan of said batteries was a definite issue. Their operational efficiency depended HEAVILY on the device being used. A Kasio [sic] keyboard, for instance, blasted at full volume by a neighbor practicing for an Independence Day botaki might need to be changed out every two songs or so, unless, of course, the neighbor is practicing at 3:00am...then the batteries had uncanny staying power. There was also the case of the "inconvenient crap-out" where a low-wattage item would die when most needed, say, during an aforementioned stroll down a rock cluttered dirt road...barefoot...three miles from your home...during the rainy season.
Batteries are, and will continue to be, a MAJOR issue in developing nations as more and more technology and goods continue to be introduced without a proper means to maintain and dispose of them after life has ended. So you can imagine my elation when I stumbled upon this website (while the technology is by no means new, continue reading to see why Freeplay is nevertheless a modernistic company):

The Sustainable Times also has a really wonderful article.
