The S.A.W.E.R. system, developed at the CTU, can uniquely produce water from air. At EXPO 2020, it has now received an award directly from the hands of Sheikh of Dubai. EXPO ends today, but the system remains in Dubai for its academic and commercial potential.

S.A.W.E.R. is a unique Czech technology that can produce water from air, even at low humidity, for example in the middle of the desert. The version that was presented in the Czech pavilion at EXPO can produce over 1,000 litres of water per day. It was awarded as the best innovation at the end of the exhibition by a Dubai government organisation under the patronage of Sheikh Muhammad bin Rashid Maktoum, the ruler of Dubai and Prime Minister of the United Arab Emirates. The unique S.A.W.E.R. system also won second place in the American Exhibitor magazine competition at the EXPO.

The Czech innovation was among several thousand others presented by over 200 nations in Dubai and among almost 500 finalists of the competition. "This is an innovation that, without exaggeration, can help people all over the world. I wish this extraordinary international success to my colleagues and I thank them immensely for spreading the good name of CTU, especially to docent Tomáš Matušek," says Vojtěch Petráček, Rector of CTU in Prague.

However, the experts from CTU are not resting on their laurels and continue to improve the S.A.W.E.R. system. They are currently working on an improved version that will withstand the cold and be usable for military purposes. At the same time, they are working on making the system smaller so that in the future, an object the size of, for example, an ordinary bottle can be used similarly as the current container.

S.A.W.E.R. (solar-air-water-earth-resources) was designed for the first EXPO in the Arab world by the Commissioner General of the Czech participation Jiří F. Potužník in 2017 and thanks to the team of the University Centre for Energy Efficient Buildings it became a real and functional technology in the following four years.

"It is clear that even a small research centre in the Czech Republic can shine at the world level. Czech science, and I don't just mean S.A.W.E.R., is once again among the best," adds Jakub Dytrich from the University Centre for Energy Efficient Buildings of the Czech Technical University in Prague.
