New water technology such as this method of seawater desalination is vital for our continued existence on this planet. However, we must no forget about ‘old’ water tech, such as rainwater harvesting and rain water tanks. Harvesting rainwater and storing this water in rain barrels or water tanks can ease the demand on other sources […]

March 22, 2013 is the 20th anniversary of World Water Day. Although about 70 percent of the earth’s surface is covered by water, only 0.001 percent is fresh and available for human consumption. The largest portion of this—70 percent—is used for agriculture. Global agricultural water consumption is expected to increase by approximately 19 percent by […]
A defence contractor better known for building jet fighters and lethal missiles says it has found a way to slash the amount of energy needed to remove salt from seawater, potentially making it vastly cheaper to produce clean water at a time when water scarcity has become a global security issue.
A significant part of the electricity needed for buildings could be generated using plant-covered roofs within a few years, thanks to research carried out at Wageningen University of the Netherlands. Similarly, fields of crops such as rice could help produce electricity without the requirement to choose between using land for growing food or biofuels. The […]
WUHAN — Chinese scientists have developed a new irrigation technology that consumes 50 percent less water than drip irrigation technology.
Billboards provide parched drivers cruising down the highway in Lima, Peru with ample ideas for ways to quench their thirst, from soda to beer, but only one turns the desert air to drinkable water right there. The billboard is a marketing campaign created by ad agency Mayo DraftFCB intended to inspire would-be engineers to apply […]
MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapour. The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up and down. Harnessing this continuous motion could drive robotic limbs or generate enough electricity to power […]
From pulling water from fog to saving fuel used to boil water, these three companies are the finalists of a contest to change the way we use our most precious resource. It’s impossible to overstate the value of water. Without it, we’d be dead.
Water experts called for urgent management of water resources and exploration of new sources in the wake of growing demand for water and huge water deficit in countries situated in the arid zone. They suggested fog harvesting a right solution to maintain greenery in the Middle Eastern countries, thus making a strong ground for such […]
