This illustration shows the principle of the Energy Tower. The tower should be sited within a hot and dry climate at relatively short distance (less than 100 km) to big water resources (normally the nearby sea). The water is pumped up to the top of the tower (chimney) and then sprayed into it. There it evaporates and thus cools down the air which as a consequence increases its density. The density difference between outside and inside air is the driving force which causes the downdraft within the chimney. This falling air is used to power turbines to produce electricity.
