I don't see how this can succeed. Kerosene is widely used as a cooking fuel also, so it's not going to be replaced by this as a power source. These 1.6 billion people who don't have access to electricity, probably also don't have access to recycling facilities...so these batteries are going to end up in a dump after 3 years, leaching heavy metals into the water supply? Or is Nokero going to ship them to recycling facilities for free? Using what kind of transportation fuel, and over what distance (Hong Kong and Sudan are pretty far apart)? What is the embodied energy of this product? Too bad that information is missing from their website. They do have some interesting information there though: fuel lanterns emit 190 million tons of carbon dioxide per year...not very much in the grand scheme of things.
