New study of Solar-powered device harvests litres of drinking water from thin air by KAUST.

 New study of Solar-powered device harvests litres of drinking water from thin air by KAUST.


Researchers at King Abdullah University of Science and Technology (KAUST) have invented a solar-powered device that can extract several liters of water from thin air daily, offering a potential lifeline for people in arid regions.

The system operates in a two-stage cycle that captures water from the air with an absorbent material and then uses sunlight to extract it in a sealed chamber. Unlike traditional two-stage systems that require manual switching, this technology automatically alternates between cycles. Inspired by how plants transport water, the system uses mass transport bridges to connect atmospheric water capture with freshwater generation.

The system generates two to three liters of water per square meter daily, suitable for drinking or farming, and has been successfully tested on crops like Chinese cabbage and desert trees. It operates continuously without maintenance, using cost-effective materials like water-wicking fabric, low-cost salt, and a plastic frame, making it affordable for large-scale use in low-income areas.

This breakthrough joins a surge of new water-harvesting technologies driven by climate-induced water scarcity. Recent innovations include an MIT device that extracts potable water from air using absorbent fins and a NASA spacesuit that recycles urine into drinking water in under five minutes.

UK Government announces first steps to reform water sector.

 UK Government announces first steps to reform water sector.

Environment Secretary Steve Reed announced initial steps to address the water sector crisis on July 11, 2024. These measures aim to stop illegal sewage dumping and attract private-sector investment for infrastructure upgrades, prioritizing customer and environmental interests. Reed emphasized accountability for water companies, planning to collaborate with the sector and investors to secure investment, create jobs, and clean polluted waterways.

He has announced: After writing to Ofwat, the Secretary of State has secured agreement that funding for vital infrastructure investment is ringfenced and can only be spent on upgrades benefiting customers and the environment. Ofwat will also ensure that when money for investment is not spent, companies refund customers, with money never allowed to be diverted for bonuses, dividends or salary increases.

Water companies will place customers and the environment at the heart of their objectives. Companies have agreed to change their ‘Articles of Association’ – the rules governing each company – to make the interests of customers and the environment a primary objective.

Consumers will gain new powers to hold water company bosses to account through powerful new customer panels. For the first time in history, customers will have the power to summon board members and hold water executives to account.

Strengthen protection and compensation for households and businesses when their basic water services are affected. Subject to consultation, the amount of compensation customers are legally entitled to when key standards are not met will more than double. The payments will also be triggered by a wider set of circumstances including Boil Water Notices.

Secretary of State for Environment, Food and Rural Affairs, Steve Reed said: We will never look the other way while water companies pump sewage into our rivers, lakes and seas.


This unacceptable destruction of our waterways should never have been allowed, but change has now begun so it can never happen again.

In summary, the government is addressing the unacceptable destruction of waterways by announcing steps to clean up the water industry, reduce sewage pollution, protect customers, and attract investment for infrastructure upgrades. This reform process, aimed at restoring the health of rivers, lakes, and seas, will unfold gradually over the coming weeks and months, supported by manifesto commitments to hold failing water companies accountable through special measures.
