Plenty of Clean Water at the Nanofrontier
The single most important application of nanotechnology could be solving the global shortage of clean water—benefiting people in both industrialized and developing countries significantly. A new podcast explores how Eric Hoek and his engineering research team at UCLA developed a new nano-membrane that promises to dramatically reduce the cost and energy needed to desalinate seawater and clean wastewater. In the near term, these membranes could work in municipal desalination plants in water-thirsty areas, such as those planned for the California coastline. In the future, this groundbreaking technology can be adapted to meet the clean water needs of poor countries and people who rely on low cost, decentralized water treatment systems.
