SunGlacier succeeded to harvest water out of extreme hot and dry air in the desert of Mali. – powered by solar energy -.
General Middendorp, Dutch Chief of Defence, invited the SunGlacier team to perform different tests at UN camp Castor in Gao, Mali.
The first results will be unveiled at the press conference, organised by The Dutch Ministry of Defence, on April 25th in The Hague.
The SunGlacier team is looking forward to testing its latest structure in ultra-harsh locations. The DC04 “Desert Twins” – with their design inspired by a Moon lander – will embark on a mission that some experts say is too extreme to succeed. We are still optimistic because SunGlacier is focused on bending the impossible to make a beneficial project into a reality.
Is it really possible to harvest usable amounts of fresh water from air in one of hottest and driest areas on this planet? To find the answer our team is transporting the Twins to the Sahara for testing in a desert with temperatures of 40C – 45 Celsius (104F – 113 Fahrenheit ) and a relative humidity less than 10%.
If the DC04 Desert Twins succeed in producing water on site in these harsh conditions, there will be proof that our concept can be used nearly anywhere. In a few weeks updates will be published on this website and our Facebook page: SunGlacier.
Keep a watch for “impossible” updates coming soon!
The Sphere for the World Expo 2017 in Estana, Kazakhstan, is nearly completed. SunGlacier is one of 4 projects that will be projected in the Sphere. Everybody entering the expo will see our project. Certainly a new highlight!
SunGlacier is invited to perform experiments in the deserts of Mali. The Dutch Chief of Defence, general Tom Middendorp made the official announcement. This will be the ultimate challenge to harvest solar water from hot and dry desert air.
The 20-inch cube of stainless steel is embedded with solar cells that power a refrigeration device, which in turn cools off an inverted cone to create condensation. Gravity then drips accumulated condensate into a glass to provide fresh drinking water. The challenge was to cool down the cone to just above freezing point without using a huge amount of energy. After several trials we managed to achieve that goal with 25 Watts of energy. The small solar panels on the top and sides of the cube produce 40 Watts, which allows to store excess energy in batteries for less sunny conditions. With the SunGlacier team we are doing research to find more solutions for cooling down surfaces in its most efficient way, off-grid, powered by solar, easy to scale up, and cheap to produce. Many people need to enjoy their own source of drinking water in the future, especially in drought-hit areas. Next to this device, we are developing a system that doesn’t have moving parts, perfectly to use for open agriculture. Later more about this new project.
Ap Verheggen, SunGlacier’s creative mind, just returned from Iran where he joined a unique Wetskills event. Ap is appointed as an ambassdor and student coordinator for the Wetskills organisation, that mix Dutch and local students, in order to find “out of the box” solutions for real life water related challenges. Many countries already participated before in the Wetskills events: United States, Great-Brittain, India, South Africa, Taiwan, etc..
Following two weeks of hard work, cooperation and fun, the fice Wetskills teams presented their pitches and posters of this Wetskills Water Challenge in Iran. The ideas pitched were vastly ranging from technical solutions to give more time in adapting lifestyle for Rafsajan pistachio farmers to integrating sensor technology to create awareness by installing a large flamingo in Lake Urmia, reacting to water level, to entice inhabitants to a race to fill up the lake. A nice new introduction of rice farming in combination with dredging was given as solution for silting up of Anzali port and peach juice production as alternative livelihoods for the Hashgerd plain included a good sense of community work and regional economy development. Missing links were noticed in society and technology for the case of clean drinking water and by closing the gaps a solution was found.
Minister of Environment and Infrastructure of Kingdom of The Netherlands, Ms. Schultz van Haegen (middle) announced and awarded the winning team of Wetskills-Iran.
Scientists from several universities in South Africa visited the SunGlacier sculpture at Museum Beelden aan Zee. They were suprised by the amount of water that the sculpture produced. South Africa is hit by drought as well, and these young generation experts were impressed by the SunGlacier technology.
