Most of you have heard about the projects being done around the slum areas of the Philippines, wherein a plastic Coke or Sprite bottle is converted into a "light bulb". Everyone can see that this solution has one very obvious drawback--it won't work at night.
Enter NOKERO, the REAL solar light bulb:
‘World’s Only’ Solar-Powered Light-Bulb | Gadget Lab | Wired.com
(from WIRED) When I was a kid, a solar-powered lightbulb was a standing joke. A light powered by light? That’s like perpetual motion. Impossible! (I was pretty nerdy even back then). But with the wonders of modern technology, the same technology that brought us food-pills and jetpacks, the solar-powered lightbulb is here.
Made by Nokero, the lightbulb is claimed to be the “world’s only solar lightbulb”, although it seems to work a lot like the solar-powered lamps that my father has had in his garden for years. Designed for campers, the light has four solar-panels which charge the battery by day and five LEDs inside which glow for up to four-hours at night.
