Fast Company reports on a solar powered lamp developed to help refugees and those in developing nations reliant on kerosene lamps. From the article:
The SolarPuff is a two-ounce, flat-pack solar lamp which quickly expands into a 4.5-inch cube. The lantern can last eight hours and easily recharges with clear sunlight. It provides enough light for refugees or people in impoverished areas to perform tasks at night, without instigating any dangerous fires or needing batteries.
