Capturing Clean Water from Power Plant Cooling Towers

Written by , on June 13, 2018

About 39% of all the fresh water withdrawn from rivers, lakes, and reservoirs in the United States is used for cooling electric power plants. Most of that water ends up in clouds of vapor. Engineers at MIT have now developed technology which captures fresh water from power plant cooling towers.  Read more »

Cheap and Efficient Ways of Using Wood To Purify Water

Written by , on May 14, 2018

Engineers at the University of Maryland’s School of Engineering have investigated ways of using energy from the sun and a block of wood smaller than an adult’s hand to heat water to produce steam point which can be condensed to provide purified water in an efficient, easily accessible, environmentally friendly, biodegradable way and at an extremely low cost.  Read more »

A Shocking New Approach to Desalination

Written by , on November 30, 2015

A team at MIT has come up with an innovative approach to treating salty, brackish or contaminated water to make it usable by using an electrically driven shockwave within a stream of flowing water. The shockwave divides the stream into two regions which are easily separated.  Read more »

Researchers from the University of Alexandria have developed a cheaper, simpler and potentially cleaner way to turn seawater into drinking water using materials that can be manufactured easily and does not rely on electricity.  Read more »

Water You Can Eat

Written by , on September 5, 2015

The London-based Skipping Rocks Lab has developed an edible alternative to plastic water bottles. Americans alone use approximately 50 billion plastic water bottles each year. Only 23% of these are recycled leaving 38 billion to decompose – a process which can take centuries. The new form of packaging, called Ooho!, is described by its makers as […]  Read more »

Lake Chad – Linking Climate, Water and Terrorism

Written by , on February 23, 2015

The changes in the lake have contributed to local lack of water, crop failures, livestock deaths, collapsed fisheries, soil salinity and increasing poverty throughout the region. All of this has turned the region into a hotbed of tribal violence and terrorism.  Read more »
