Our MAGDA received two patents

The University Centre for Energy-Efficient Buildings of CTU has completed the development of a mobile autonomous device for extracting water from air humidity, which will fit on the back of a regular van and will function as an emergency source of water in a desert environment. His functional sample successfully passed tests in the laboratory and obtained two Czech national patents with a view to their expansion abroad.

The MAGDA device (Mobile Autonomous water Generator from Desert Air) passed the test in the laboratory of CTU UCEEB, where high temperatures and low specific air humidity were maintained. A harsh test in the desert was also planned, which was temporarily postponed due to anti-epidemic measures. It is still expected to take place if a suitable opportunity arises. Water production for the temperature and humidity conditions of the desert was measured in the range of 0.6 to 1.5 l/hour with an energy consumption of 2.3 to 2.9 kWh.

MAGDA consists of two boxes (overall dimensions 1 x 1 x 1.4 m) and a photovoltaic field with an area of 35 m2. The device is designed to have an average water production of 10 l/day. One box is intended for the production of drinking water, the other provides electrical energy to drive the entire device.
