desalination, Kenya -

  Converting seawater into safe drinking water at a large scale takes an enormous amount of energy, which makes it a costly and polluting process. Now, a Dutch-based blended finance manager Climate Fund Managers (CFM), and Solar Water Solutions are working together to develop the installation of up to 200 desalination units in Kitui County, Kenya. The project eventually aims to provide clean water made of brackish groundwater for 400,000 Kenyans by 2023. The new solar-powered desalination system works without connecting to a grid, without any batteries or chemicals, ever. This means the system will need zero battery investments, zero running costs,...

Safe and readily available water is important for public health, whether it is used for drinking, domestic use, food production, or recreational purposes. Despite the vast quantity of water on Earth, just 2.5% of it is freshwater, and an estimated 785 million people lack a clean source of drinking water. Desalination of seawater could be a vital technology to meet the world’s drinking water needs. Now, Korean engineers have developed a new desalination technique that takes just minutes to make seawater drinkable.   They used a new nanofiber membrane distillation process that could desalinate water with 99.99% efficiency. Engineers believe that commercializing such technology could...

According to the World Health Organization (WHO), roughly 785 million people worldwide lack a clean source of drinkable water. Desalination could be the key to meet the world’s drinking water needs. This year, we have seen a few different ways to desalinate water, including a desalination device that also harvests lithium & H2 from seawater affordably and a portable lamp that converts half a liter of saltwater into 45 days of light. Korean engineers have developed a nanofiber membrane that turns seawater into drinkable water by a membrane distillation process. In addition, the membrane can operate efficiently for long periods. In this process, the...

Jun 18, 2019   In early 2018, Cape Town, South Africa came dangerously close to being the world’s first major city to run out of water. People lined up for blocks to collect spring water. Stores sold out of receptacles like buckets and bowls. Bottled water was rationed in tourist-heavy parts of the city. April 12 was designated “Day Zero”—the day the water was expected to dry up. City officials prepared for riots, keeping army and police ready to be deployed to water collection sources. Rainfall in the region had been low for three years straight, prompting a drought. Thanks to...
