Developing World

The need for water innovation is greatest in the developing world, and while the end user rarely has the ability to pay for the technology, aid organizations and NGOs often do. That’s the market that Puralytics, a Beaverton, Oregon-based start-up, is targeting with the SolarBag. The company, which also makes water purification technology for high-tech laboratories, has developed a three-liter bag, lined with nanotechnology-coated mesh. When exposed to the sun, the bag can purify dirty water in a matter of hours and be reused hundreds of times.
