This article focuses on the ReadySet- a one-stop solar charging device with lantern- that was designed for use in Uganda, but has found demand in the US as well. It is a case study in "trickle-up innovation," and a "slick product designed for the bottom of the pyramid for first world consumption." The fact that this concept works (and is certainly not the first) has important ramifications. Not only does it spread the benefits of clean energy to those who effectively have no energy, or an unreliable supply, but also to markets here in the US where energy is abundant and accessible. The environmental burden therefore becomes more equitable, at least in theory, and not concentrated on the developing world exclusively. Secondly, the higher margin potential in more affluent markets allow a greater buffer for innovation, which can be used to specialize the product or service in developing markets. Ideally, this model may become a template for greater success in the sector.
