Millions of people around the world live in darkness without access to lightbulbs and power. Within dense city-slums, windows are few and far between so people often open up a skylight in the roof to allow light in. A clever trick has been to place a 2L Bottle with water to disperse light and a little bleach to discourage microbial growth. Yet what about nighttime? What then? Perhaps an even better solution is a waterproof LED within the bottle, connected to a small solar panel and a battery system.
Can we leverage the power of Crowdsourcing to design something to improve the lives of other in lesser-developed countries? Can we utilize new technologies like inexpensive 3D Printers like a Reprap to prototype and manufacture those designs as they are needed, using what components are readily available. GrabCAD thinks so.
We have 4 LEDs, a single 7.5V 220mA Solar Panel, two NiHm batteries and a 2L Coke bottle. Using these components, design the casing for the LEDs so it can be inserted into the bottle, as well as the case for the panels and batteries. The designs will be made by our custom 3D Printer, a massive machine measuring 600 mm x 400 mm x 600 mm which uses similar extrusion techniques to the Makerbot.
