The CTU University Centre for Energy Efficient Buildings exhibited at the Czech national stand at the OZWATER´23 fair in
Sydney the EWA (Emergency Water from Air) device, which is the latest addition to the S.A.W.E.R. family of systems for producing
water from desert air. The new product was developed in cooperation with KARBOX s.r.o., a leading Czech manufacturer of containers,
container and box bodies.
It is a mobile device for extracting water from the air in the desert environment, which, thanks to its parameters, is currently
unrivalled on the market. Its average daily water production in the desert is 25 to 35 litres. Of course, it can also be operated
in wetter environments where it can produce from 50 to 70 litres of water per day.
Firstly, the prototype has been tested for six months in our laboratories in Bustehrad, where we simulated desert climatic
conditions. Before the OZWATER'23 trade fair, we had tested EWA in the real environment of the very dry Australian outback.
There, the device generated an average of 25 litres of water per day for several days.
The Australian outback is facing a growing shortage of drinking water and therefore a high price for bottled water. Therefore,
EWA has the potential to be commercially successful and gain recognition similar to its sister technology S.A.W.E.R., which
produced water from desert air for the Czech national stand at the EXPO 2020 World Expo in Dubai, where it won the award for
best innovation.
