New Nanotechnology to Clean Polluted Water

Written by , on May 9, 2013

Scientists from Australia's Deakin University, together with French colleagues, say that they have manufactured a lightweight and reusable material that can absorb up to 33 times its weight in a wide range of spilt oils, chemical solvents and dyes, while repelling water. Deakin University's Dr Wei Wei Lei said that "The effective removal of oils, organic […]  Read more »

Nanotech Device Purifies a Family’s Water for $2.50 a Year

Written by , on May 8, 2013

Researchers at the Indian Institute of Technology in Madras have developed a simple point-of-use water filtration technology,using nanomaterials to filter and clean the water, which they say is effective for producing drinking water at a cost of just $US2.50 per year per family. The device uses a two-stage process to purify the water. In the […]  Read more »

A Billboard That Produces Drinking Water

Written by , on February 25, 2013

Peru's capital, Lima, has very high humidity but hardly any rain. Engineers from the University of Engineering and Technology have taken advantage of the high humidity to build a billboard which gathers the water through reverse osmosis and purifies it to give clean drinking water.  Read more »

Glass “Sponge” Separates Oil from Water

Written by , on October 23, 2012

Dr. Paul Edmiston and students at the College of Wooster in Ohio have discovered a material which absorbs small organic molecules while repelling water. The material, which they call "Osorb", is a nano-engineered glass that can absorb hydrocarbons, volatile organic compounds, pharmaceuticals, pesticides, and solvents which are either dispersed or disolved in water. The absorbed […]  Read more »

Producing Energy by Treating Waste Water

Written by , on August 13, 2012

Israeli company, Emefcy, has developed a microbe-based technology that harvests energy while treating waste water. The process starts with the same principle as most wastewater treatment – water is aerated so that bacteria in the liquid breaks down organic material. But instead of using electricity to push air into the water, Emefcy uses a permeable, […]  Read more »

Building Cladding Controls Heat & Purifies Water

Written by , on June 22, 2012

The Center for Architecture, Science and Ecology in New York has come up with a building exterior that not only helps the interior comfortable but purifies water. The exterior surface of the building is clad in modular glass blocks which are configured to capture, refocus and intensify sunlight. Greywater from sinks, showers and hand washing […]  Read more »

Monarch Power, a private research and development company in Arizona, is developing a lotus-shaped solar collector that is expected to produce up to 3 kilowatts of solar thermal power, as as well as steam for heating. The company also expects that the solar concentrator could be used to produce up to 3 kilowatts of solar […]  Read more »

Clean Drinking Water Using “Miracle Tree” Seeds

Written by , on June 19, 2012

The moringa oleifera is known as the “miracle tree” because it has been used in northern India and many parts of Africa for traditional medicine, food and cooking oil, a pesticide, a domestic cleaning agent and biofuel. Moringas are extremely hardy. They grow on marginal soils, regrow after being chopped down and are one of […]  Read more »

Using Satellites to Save Water

Written by , on January 7, 2011

NASA researchers have developed a system to help farmers better manage irrigation systems. The system uses data from NASA satellites, local weather observations and wireless sensor networks installed in agricultural fields to calculate water requirements of crops in individual fields and provide farmers with the information immediately. Water requirements and forecasts can be accessed from […]  Read more »
