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 »

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 »

New Approach to Rice Growing Increases Yields and Reduces Water Use

Written by , on November 10, 2010

Oxfam America is promoting a new approach, called "the System of Rice Intensification" or SRI, for small farmers which helps them produce more rice at lower cost without relying on harmful fertilizers and pesticides that can decrease soil fertility and threaten clean air, soil, and water. Farmers using the SRI method simply transplant younger seedlings […]  Read more »

More Rice with Less Water
