The exceptional feature-length documentary "Let there be wate?!? charts the creation of a Czech invention that aims to obtain drinking water even in the driest places on the planet and establish oases in deserts at almost zero cost. The film, which is produced by the company Bio Illusion, premieres on November 23, 2021 and will be released in Czech cinemas on November 25, 2021.
The collective documentary about the Czech invention called SAWER (Solar-Air-Water-Earth-Resource) describes the events that influence, change and determine the Czech participation in the EXPO 2020 exhibition. The film about a two-year battle with the circumstances presents seven courageous Czech scientists who married into his head that he will make a device that is the only one that can obtain water even from the dry desert air. The research and development of the device was carried out by scientists from the University Centre for Energy Efficient Buildings of CTU in Prague and from the Institute of Environmental Technology, Faculty of Mechanical Engineering of CTU in Prague.
The film maps the assembly of SAWER, its testing in the laboratories in Buštěhrad and finally in the desert conditions of the United Arab Emirates. It is embedded in the wider context of the problem of water scarcity in many areas of the world. A Czech invention obtains water from the dry desert air, which can be used not only to irrigate plants for food production, but also mainly as drinking water for people and livestock. The only thing SAWER needs to produce water is solar energy and air.
