Solar Bottle

One sixth of the world’s population has no access to safe drinking water, increasing their risk of waterborne diseases such as diarrhea, cholera, typhoid fever, Hepatitis A and dysentery. In this scenario, the Solar Bottle designed by Alberto Meda and Francisco Gomez Paz is indeed commendable.

The duo have designed a container that brings the best out of the SODIS system, a simple, low-cost solution for treating drinking water at a household level. Contaminated water is filled into transparent plastic bottles. When exposed to full sunlight for six hours, the pathogens in the water are destroyed.

The Solar Bottle has one transparent face for UV-A + infrared rays collection and one aluminum color to increase the reflections. The high ratio surface/thickness of the low cost four liter container improves the performance of solar disinfection and its flat shape makes it stackable and facilitates storage. A handle makes it possible to regulate the angle for best solar exposition and ensures easy transportation.

The design won the duo the INDEX AWARD last year.
