Where Sun Meets Water

As solar power technology advances, its versatility increases in mobile, off-grid applications. Relief organizations such as the Solar Electric Light Fund deliver power and communications technology to remote villages, providing nighttime illumination, refrigeration of medicines, and internet access. One of the greatest benefits of remote solar power, however, is its ability to deliver drinking water via pumping and filtration. Princeton-based WorldWater & Solar Technologies has developed a series of mobile solutions based on solar-powered water delivery. Their Mobile MaxPure Freshwater system provides 30,000 gallons of fresh water in a year for under 1 penny per gallon, and can also generate up to 3.5kW of solar power. WWST also manufactures units that supply potable water from brackish sources (5,000 gallons) and seawater (3,000 gallons).
