At the end of February 2020, the SAWER autonomous device in a container design returned to the Bustěhrad CTU UCEEB laboratories after six months of testing in the United Arab Emirates. The test operation in the desert confirmed the potential to produce water without the need for external energy in an estimated amount of around 100 liters per day.
As a next step towards the commercial use of the device, scientists from the Energy Systems of Buildings team of the Czech Technical University UCEEB are now proposing a simplification that will facilitate installation at the place of operation. This mainly consists in the realization of a prefabricated solar roof over the containers (structure, solar collectors). All material for the solar roof is stored in containers for transport to the installation site.
After modifications, four workers should be able to get the system up and running in three days, while the installation of the first prototype in the desert took five experts a full 11 days. The time commitment was due to the experimental nature of the facility and the trial of different technologies using local renewable energy sources for the process of extracting water from the air.
