Atmospheric water generators (AWGs) sound like magic: machines that can pull drinking water out of air. The idea is mentioned in the Bible, where the elders would pray for water collected as dew on plants and the catch on turning this into a machine is in the physics. To turn invisible vapor into liquid, you must remove heat, especially the latent heat of condensation. In real machines, that usually means refrigeration (cooling air below its dew point) or heating/desorbing moisture from sorbents. Either way, energy use rises fast as humidity drops. While many solutions exist on the market, the solutions aren’t magic. Too much energy needs to go into the AWG machines to make the water from thin air concept work.

Peer-reviewed assessments put many active AWGs in the rough range of ~0.35 to >1.1 kWh per liter depending on climate and design see this paper. A broader scientific review of atmospheric water harvesting thermodynamics estimates maximum yields around 0.34 to0.73 L/kWh under various assumptions, equivalent to roughly ~1.4 to 2.9 kWh per liter in the “best case” envelope. See PNIH resource. Lab and field results can be lower or higher depending on temperature, humidity, airflow, and heat exchange losses.

The core problems of AWG, water from air generators

• Low humidity = tiny water per cubic meter of air. The drier the air, the more air you must process to get a liter, which means bigger fans, larger heat exchangers, and more power.
• Cooling penalty. Condensation-based AWGs must cool air below dew point; that’s energy-intensive, especially in hot-dry regions where dew point can be very low.
• Heat management. You must dump heat to the environment (or recover it). Poor heat rejection and frosting risks can crater performance.
• Water quality isn’t “free.” Collected water still needs filtration/UV/mineralization and safe storage, adding energy and maintenance.

So how can AWGs be solved?

The most promising pathways don’t “beat physics” — they change the system boundary:

• Use low-grade heat or solar thermal to regenerate sorbents instead of running compressors. MOF-based devices have shown solar-driven harvesting in arid climates (Kim et al., in this 2018 Nature article).
• Hybridize with HVAC/dehumidification you already pay for to run. If a building must remove humidity anyway, capturing and polishing that water can be “incremental” rather than “extra.” While it might not run showers, the water can be used to water gardens or flush toilets. See our article on top uses for AC water.
• Raise efficiency via better sorbents + heat recovery. New cycling strategies and materials aim to cut regeneration energy and speed cycles (Kang et al., 2024).
• Target the right use cases. Emergency backup, remote sites, islands, and places where trucking water is expensive can justify higher kWh/L.

10 promising companies in the AWG space

1. SOURCE Global (solar “hydropanels”) — promising for off-grid drinking water where sunlight is abundant (SOURCE how it works).
2. Watergen — large deployments and claimed efficiency improvements; best fit in warm/humid conditions. See our past article on Watergen.
3. Genesis Systems — containerized systems positioned for disaster resilience and humid climates.
4. Aquaria — scaling “water from the sky” for housing developments; success depends on cost per liter vs local supply (Time on Aquaria).
5. Skysource / Skywater Alliance (WEDEW) — notable for renewable-energy framing and resilience applications (XPRIZE profile).
6. AirJoule — one to watch if real-world data confirms lower energy via novel separation/recovery approaches (AirJoule investor deck).

   

7. Uravu Labs — interesting liquid-desiccant path tied to renewables and local bottling models (Mongabay India).
8. Kara Water — consumer appliances; compelling product story, but energy economics must be transparent (Kara Water).
9. EcoloBlue — long-running commercial/home units; performance varies heavily with climate (EcoloBlue specs).
10. WaHa from Saudi Arabia is positioning around “water + dry air” and grid-independent operation; worth watching for verified field performance (WaHa). Professor Omar Yaghi, a distinguished chemist from the University of California, Berkeley, and pioneer of reticular chemistry (inventor of Metal-Organic Frameworks/MOFs). Born in Jordan and working in California, he was awarded the 2025 Nobel Prize in Chemistry, shared with Richard Robson and Susumu Kitagawa, for this work. Waha is active in Saudi Arabia and the UAE.

    

    

AWGs are rarely the cheapest way to make water where pipelines, wells, or desalination are available. They are commonly used by armies to create water in remote locations where energy isn’t an issue. Diesel or solar does the heavy lifting. But as materials improve, and as systems tap waste heat, solar thermal, or existing dehumidification loads, AWGs can become a practical niche tool, especially for resilient, point-of-use drinking water in the places that need it most in off-grid sites and in emergency settings.

Let’s aim for the day when fusion energy is real, and we can all pull water from the air to drink. Just add some Mayu minerals to make the water work well for your body.

The medical cannabis boom felt in Israel may show signs of a giant cooldown. Syqe was one of the darlings of the medical cannabis pharma space, as a doseable drug. This is an industry I helped spark into life when I started the Canna Tech Conference in Jaffa about 10 years ago. Much has changed and a lot of the hype has died down, mainly due to loosened restrictions on access to cannabis, making it easy for people to self medicate in the United States and Canada.

One of the challenges in cannabis as medicine is dosing (read this article on half of all medical cannabis drugs being mislabled). What’s written as THC or CBD concentration may be far from what’s inside the plant or how it affects your body, and how it’s delivered. Syqe, an inhaler dosing system in Israel promises to make dosing a pharmaceutical science, but in waiting for the coveted US FDA approval, Syqe says it needs to lay off 50 of its staff of about 150 based in Tel Aviv. If their product works they may be actually a solution to the mislabeling.

The company grew into medical marijuana stardom when Philip Morris / PMI, the cigarette company invested $20 million in 2016 and later entered into an agreement to acquire the company for ~$650 million, contingent on regulatory success. In that acquisition plan, PMI committed $120 million to push Syqe’s inhaler device through U.S. FDA regulatory hurdles. Is the money running out without results?

This backing gave Syqe financial muscle and strategic reach—but also raises reputation and strategic risks, given tobacco’s fraught public perception in the health space. Imagine if McDonald’s bought into a regenerative kale farm. The cash infusion could scale production, but people would always wonder if the lettuce was being served with a side of fries.

According to recent news Syqe Medical recently cut 50 employees, about 32% of its workforce, with the majority coming from its development (R&D) department. If the company succeeds or not, is only an insider’s guess. The inhaler uses a unique cartridge containing dozens of “VaporChips,” each holding a measured dose of cannabis flower, allowing accurate administration according to a doctor’s prescription. The question is does it work in dosing, can it work? Sometimes funds run out before the right tests can be checked and confirmed by the FDA.

On the general issue of cannabis, if you are traveling to Dubai or Abu Dhabi, take note: medical cannabis, even if only in your blood, and self-medicated can land you in jail according to the law in the United Arab Emirates. Even CBD oil is a risk.

In 2012, Green Prophet sounded the alarm about depleted Gulf fish stocks and weak enforcement in Dubai. Revisit Tafline Laylin’s original piece here: Dubai Finally Gets Serious About Overfishing.

Thirteen years on, what’s changed—and what hasn’t? Regulatory frameworks are clearer. The UAE now requires licences for commercial and recreational fishing and sets rules on species, sizes, seasons, and gear. See the official portal: Regulating fishing practices (UAE).

Marine protection and monitoring have expanded. Authorities report more scientifically informed monitoring and new research capacity,including offshore survey capability and support vessels for fisheries and habitat assessment (overview at Life Below Water – UAE.)

Emirates, the UAE airline, is giving aviation waste a second life—and a stylish one at that. Following the rapid sellout of its 2023 launch, the Dubai-based airline has unveiled a second limited-edition collection of handmade bags crafted from retired aircraft interiors.

The Aircrafted by Emirates 2025 Collection includes 167 collector pieces now available for purchase through the Emirates Official Store. Like the first drop—which raised over $17,000 for children via the Emirates Airline Foundation—most proceeds will again support children in need, blending sustainability with social impact.

Each bag in the new collection is a one-of-a-kind artifact from aviation history. Materials have been salvaged from Emirates’ retrofitted Airbus A380 and Boeing 777 aircraft—upcycled elements like aluminum headrests, leather from First and Business Class seats, and even the faux-fur covers from the Captain’s chair.

The result? A line of thoughtfully crafted trolley bags, backpacks, and handbags, ranging in price from $80 to $350. Some feature functional Emirates seatbelts as straps. Others are lined with brand-new fabric and include hardware upgrades like zippers and leather conditioning. All materials are laundered, deep-cleaned, and disinfected before being reimagined into luxury bags.

What makes this even more impressive is that the entire collection is handmade by Emirates’ own cabin tailors—a 14-person team usually tasked with maintaining aircraft interiors. Now, thanks to the growing popularity of the initiative (including a special Aircrafted Kids line), these artisans are working full-time on creative reuse. We hope they are getting a good wage.

This isn’t a PR gimmick, so they say. The project is a spinoff of Emirates’ massive fleet retrofit, launched in 2022—a multi-billion-dollar effort to upgrade 219 aircraft. So far, the airline has reclaimed more than 30,000 kilograms of high-quality aircraft materials, proving that large-scale industrial projects can have a second life, with both aesthetic and environmental benefits.

Aircrafted by Emirates offers a new kind of aspirational shopping experience—luxury that’s upcycled, local, and charitable. For consumers looking to reduce their carbon footprint without sacrificing quality or design, this initiative points to a broader future for sustainable fashion in the Gulf and beyond.

And yes, if past demand is anything to go by—these bags will fly off the shelves.

If you think of the Middle East, sand, not soil comes to mind. But the complex ecosystem which includes Turkey, Lebanon, Israel, Iraq, Iran and the United Arab Emirates has a rich soil tradition, the Levant especially as it is once considered the bread basket of the planet, and it’s where emmer wheat was first cultivated.

Now the United Arab Emirates has declared they will build a soil museum of the Middle East. Like seed banks, dispersed in underground vaults and fridges throughout the world, a soil bank can help us know more about the complex and rich ecosystems of the east.

Designed to promote soil conservation and responsible resource management in arid environments, the guide will serve as a blueprint for institutions across the region. Backed by ADFD funding, the guide will be transformed into a practical training and capacity-building programme featuring technical workshops and scientific mentoring. ICBA will lead the technical delivery, drawing on its expertise in sustainable agriculture and its success in launching and operating the Emirates Soil Museum.

The Abu Dhabi Fund for Development (ADFD) and the International Center for Biosaline Agriculture (ICBA) will fund and develop the Middle East and North Africa’s first comprehensive guide for establishing and operating soil museums.

Mohamed Saif Al Suwaidi, Director General of ADFD, said: “This initiative reflects our unwavering commitment to environmental sustainability and knowledge partnerships. We believe science-backed solutions like this museum guide can shape regional resilience and inform effective policies for generations to come.”

The agreement also outlines the organization of an international scientific symposium on 5 December 2025 to coincide with World Soil Day, with the participation of over 200 experts, researchers, and decision-makers from around the world to discuss soil, salinity, and climate change issues in arid regions.

Established in December 2016 with support from ADFD, Emirates Soil Museum is the first specialized soil museum in the region. Located at ICBA’s headquarters in Dubai, the museum aims to raise awareness about the role of soil in the environment, agriculture, and food security, while showcasing the diversity of soil types in the UAE.

Since its launch, the museum has welcomed more than 13,500 visitors from various sectors of society and has become a reference center for environmental awareness and non-traditional education. Time for a wider understanding of soil and how it sustains life.

Tucked away in the red sands at the base of Mount Alvaah in Sharjah, Al Faya Lodge is a striking blend of contemporary design and desert heritage. Designed by the Dubai-based architecture studio Anarchitect, the boutique hotel and saltwater spa reimagine two stone buildings originally constructed over 50 years ago. Once a clinic and a grocery shop, these modest structures have been transformed into a luxurious five-room retreat that embraces both sustainability and the rich history of the UAE’s desert landscape.

Al Faya Lodge is a delicate balance of old and new. The original stone buildings have been preserved and enhanced with thoughtful interventions that give them a new purpose. To preserve the spirit of the desert, Anarchitect used local materials like concrete and stone in the new structures that complement the original buildings. Weathered steel, with its striking rust hue, was chosen to highlight these additions, tying the design to the rich iron ore deposits found in the region. This use of metal not only reflects the area’s natural landscape but also nods to its industrial history, being near one of the UAE’s first petrol stations.

The lodge’s design takes the region’s extreme climate into careful consideration. Sharjah’s desert environment presents a unique set of challenges, from searing heat and prolonged sun exposure in the summer to chilly nighttime temperatures. Jonathan Ashmore, Anarchitect’s founder, emphasized that any design in such an environment must account for these factors. “The elements—sunlight, sandstorms, and temperature swings—require materials and designs that are both durable and practical,” he explains. The team rose to this challenge by creating raised terraced decks, over-sailing roofs, and shaded screens to keep the hot sun at bay, while also ensuring comfort for visitors.

Durability was a key factor when choosing materials. Polished concrete, granite, and travertine were selected not only for their ability to withstand the desert’s elements but also for their beauty. Hardwood and plastered-render were incorporated to weather naturally over time, enhancing the building’s aesthetics while ensuring a long lifespan in the harsh desert climate.

Each of the five rooms at Al Faya Lodge has been designed with star-gazing in mind, featuring skylights to give guests an unobstructed view of the desert sky. The master suite even has a private roof terrace, perfect for soaking in the serene surroundings. The lodge can be booked in its entirety, offering exclusive use of the saltwater spa and open-air swimming pool, along with access to other luxurious amenities, including a dining room, reception area, and an outdoor terrace with a fire pit for evenings spent under the stars.

The result is a desert retreat that celebrates both the timeless beauty of the landscape and the importance of sustainable architecture. Al Faya Lodge’s thoughtful design invites guests to reconnect with nature, while also showcasing how modern architecture can thrive in some of the world’s most extreme climates. With its perfect blend of luxury, comfort, and environmental sensitivity, Anarchitect has created a one-of-a-kind destination that sets a new standard for desert architecture.

ADQ, an Abu Dhabi-based investment company, the Environment Agency – Abu Dhabi (EAD), the region’s largest environmental regulator, and Archireef, a climate technology company based in Hong Kong, have deployed artificial 3D printed terracotta reef tiles to aid coral restoration in the Persian Gulf off the shore of Abu Dhabi.

The tiles were designed by a team of marine biologists and architects and produced through custom 3D clay printing in Archireef’s new production facility.

The partnership between ADQ and Archireef funds research and development of eco-engineering solutions for marine biodiversity restoration – combining scientific research with the use of the latest technologies in 3D printing, IoT, and AI.

“Our partnership with Archireef brings a unique and innovative coral restoration method to Abu Dhabi to safeguard our Emirate’s natural environment and promote sustainable development. It is a memorable moment for ADQ to be part of this project providing a lifeline to endangered coral reefs, which is the first of its kind in the UAE and the wider region.

Underlining our commitment to adopting practical solutions powered by R&D and innovation to address environmental challenges, this biodiversity restoration initiative aligns with our ESG aspirations, and we believe it will have a positive impact not only on our planet but also on local communities we operate in,” said Anas Jawdat Albarguthi, Chief Operating Officer at ADQ.

In contrast to other types of artificial reefs, the 3D printed terracotta reef tiles are environmentally friendly and engineered to closely mimic the natural pattern of corals and prevent sedimentation build-up, which is a major threat for corals. It basically chokes them.

The plantation site is at Um Khorah Island in the Al Dhafra Region, in Abu Dhabi, housing around 1,200 coral fragments grown in specialized nurseries, owned by EAD.

Abu Dhabi waters are home to 34 different types of hard coral. In 2017 alone, the Emirate lost most of its corak, 73% of its reefs, due to mass coral bleaching, caused by an increase in water temperature due to climate change, manmade coastal disruption and the shipping industry and pollution.
