This desalination device delivers cheap, clean water with just solar power

In a coastal city in Namibia, a small shipping container near the beach sits surrounded
by solar panels. Inside, new technology uses that solar power
to turn ocean water from the Atlantic into drinking water.

Namibia is in the middle of a prolonged drought. The president recently declared the second state of emergency in three years because the lack of rain is leading to severe food shortages. But if scaled up, this technology could help supply households and agriculture with fresh water. The basic tech that it uses for desalination, called reverse osmosis, isn’t new. But because the system can run on solar power, without the use of batteries, it avoids the large carbon footprint of a typical energy-hungry desalination plant. It’s also significantly cheaper over the lifetime of the system.

South Korea is building a $10 billion agriculture city in Egypt

IMG_3355

Within six months, 311,400 acres of land in Egypt will be transformed into an agriculture city. The $10 billion deal was signed on Tuesday by Egypt and the Korea-Arab Society (KAS). The project will feature 50,000 smart greenhouses in addition to a number of seawater desalination and solar power plants.

Graphene oxide could offer a solution to unlocking our most abundant water source

Many of us struggle to satisfy our thirst even though we live on a water world.  That is because the Earth’s oceans are salty. Just 2.5% of the Earth’s water is freshwater, and of that, 60% is trapped in glaciers, 30% in groundwater (not all of which is accessible), and just 10% is on the surface in lakes and rivers.

Mobile Water Purification Offers Hope To Disaster-Hit Regions

Courier Water

Water shortages are a growing problem around the world, especially in developing countries. Desalination, or turning seawater into potable water, is one way of increasing water supplies, but desalination plants require vast amounts of energy and infrastructure. Now a Japanese team has developed Courier Water, a mobile desalination unit that has tremendous potential for helping people in areas affected by water shortages or natural disasters. The unit’s defining feature is its mobility. With its compact design, Courier Water can be installed on a four-ton truck, allowing it to travel far and wide.

New Chlorine-tolerant Material Could Streamline Desalination Processes

New Chlorine-tolerant Material Could Streamline Desalination Processes 

 

Getting access to drinking water is a daily challenge for more than one billion people in the world. Desalination may help relieve such water-stressed populations by filtering salt from abundant seawater, and there are more than 7,000 desalination plants worldwide, 250 operating in the United States alone. However, the membranes that these plants use to filter out salt tend to break down when exposed to an essential ingredient in the process: chlorine.
