Solar Bottle: Purify water while the sun shines
When great design meets great utility, a product like the Solar Bottle is born. The Solar Bottle is the brainchild of Italian designers Alberto Medo and Francisco Gomez Paz. The designers were introduced to the SODIS (Solar Water Disinfection) system at Milan's International Furniture Fair and were inspired by this effective but inexpensive method of purifying household drinking water.
The SODIS system is based on the fact that when water is filled into transparent PET bottles and exposed to six hours of sunlight, the UV-A radiation and increased temperature from the solar energy will effectively kill disease-causing pathogens in the water. In an effort to design a container that does maximum justice to this technology, the duo created the award-winning Solar Bottle (still a prototype).
The design definitely does complete justice to the intent. Each 4-liter bottle is flat to allow easy stacking and has two sides – one transparent side for collection of UV radiation and another dark side for adequate heat-absorption. The sturdy handle not only makes the bottle easy to carry, but also doubles as a stand while it is being exposed to sunlight. This simple technology combined with the great (and yet affordable) design conceals within itself the immense potential to save millions of people around the world who have meager-to-almost-nil supply of safe drinking water. We hope this product soon sees the (sun)light of day.
