In spite of the technological age we live in it is reported that one-in-five people on this planet still don’t have access to clean drinking water. To help correct this imbalance, a new, energy-efficient desalination plant with an expected production capacity of 30,000 cubic meters per day will be built in the city of Al Khafji, Saudi Arabia, to serve its 100,000 people. Known more for its computers, IBM has joined forces with KACST (King Abdulaziz City for Science and Technology) to build the plant that will be powered by ultra-high concentrator photovoltaic (UHCPV) technology - a system with a concentration greater than 1,500 suns.  Read More

A single unit of the new desalination device - in the Y-shaped channel (in red), seawater ...

Following natural disasters such as the Haiti earthquake and Hurricane Katrina, potable water is often in high demand and short supply. In both of those instances, the disaster zones were near the sea, but converting salty seawater to potable fresh water usually requires a large amount of dependable electrical power and large-scale desalination plants - neither of which were available in the disaster areas. A new approach to desalination, called ion concentration polarization, could lead to small, portable desalination units that could be powered by solar cells or batteries and could deliver enough fresh water to supply the needs of a family or small village.  Read More

“In the developing world, more than 1 billion people cannot get clean drinking water... The United Nations says that dirty water causes 80 percent of diseases in the developing world, and kills 10 million people annually.” Those sobering lines are from the United Nations’ website, and underscore just how urgently needed water purification is in much of the world. What many people don’t realize, however, is that there are already naturally-occurring water filtration supplies available in many of these areas. They come in the form of seeds from the Moringa oleifera tree, and used properly, they can produce a 90.00 to 99.99% bacterial reduction in previously untreated water.  Read More

The deployment of MMP units in Darfur Refugee Camps has brought  clean water and power to ...

Recently we reported on Marines and their deployment of GREENS solar-power for technological devices on the battlefield. World Water and Solar Technologies (WWST) has also placed solar-powered water purification units throughout the world including war-torn Darfur, Sudan. Working with the Humanitarian International Services Group (HISG), two high-volume Mobile Max Pure (MMP) water filters have been installed that use the sun for their power. Placed in a carefully selected location where it could do the most good, each unit can generate up to 3.5kW of solar electric power and provide 30,000 gallons of clean drinking water for the many thousands of displaced civilians.  Read More

Thirst Aid – on-the-fly water purification

Pure Hydration’s Thirst Aid makes a lot of sense. If you’re ever inclined to go adventuring, particularly where the water is dodgy or outright dangerous, the robust pouch is light and does the job on the spot – just pour in the dirty water, wait a while, and then squeeze out the clean water. Good for 300 liters.  Read More

The ingenious Aquaduct Mobile Filtration Vehicle

April 9, 2008 A staggering 1.1 billion people worldwide lack access to clean drinking water, with an estimated 5,000 children per day dying from water-related diseases. In response to this global crisis, a group of inventors from the US developed the innovative and highly commendable Aquaduct Mobile Filtration Vehicle - a tricycle which uses pedal power to both transport and filter clean drinking water.  Read More

Sharp's new air purifiers combine purification and humidification

Sharp has released two new air-purifiers that combine three technologies to quietly and efficiently clean and refresh air in the home. The KC-C100U and KC-C150U use a triple filtration system, Sharp’s Plasmacluster technology and a humidification function to trap dust and pollen, decrease odors, and freshen and humidify the air.  Read More

Katadyn Vario Water Filter

December 10, 2007 The Vario from Swiss water purification specialists Katadyn provides a versatile solution to the age old problem of avoiding stomach bugs while on the trail. Capable of producing up to two liters of filtered water per minute, the Vario gives the user a choice between two or three different filtration stages - one for when speed is required and and a second for extending cartridge life.  Read More
