This $5 Solar Lamp Replaces The Fumes And Fire Risk Of Kerosene Lanterns

The SolarAid lamp is designed for "off-grid families and school children," and is both cheap to buy and cheap to run. It's tough, and unlike kerosene you don't need to buy fuel for it. It won't choke children while they do their homework, and it is twice as bright as a kerosene lamp.
