Although we have entered 2012 approximately 1.5 billion people around the globe remain without access to a stable or safe source of light. Commonly in some of the world's poorest regions, kerosene lanterns are the standard form of night time lighting, which leads to the possibility of fires, explosions, asphyxiation and toxic fumes. Cheap, accessible solar lighting presents an obvious solution to this problem and the latest tilt at making this a reality is WakaWaka - a solar LED lamp concept that can fit snuggly onto a soda bottle.
WakaWaka lamp is a solar charged, portable LED lamp that hopes to hit the market with a low US$10 price tag, which is the equivalent of 2-3 months worth of toxic kerosene fuel. Unlike its competitors, the WakaWaka promises to provide 16 hours of light from one day of solar charge. Solar Pebble comes close with 12 hours of light but the others fall behind with only 4-6 hours of usage time.
