Apparatus for obtaining fresh water by artificially generating a precipitation. The apparatus comprises at least one darkening body that forms a darkening surface which has a width and/or length of at least 3 km and an albedo of less than 0.1. The apparatus further comprises at least one base frame which is arranged on a ground and configured to support the at least one darkening body so as to keep the at least one darkening body spaced apart from the ground in order to form a space between the at least one darkening body and the ground. Still further, the apparatus comprises a precipitation collection system which is arranged at least partially within the space and configured to collect the precipitation falling on the darkening surface.

Electrical-power generating module, characterised in that it comprises at least one wind turbine (E) having blades (E1) forming blade tips (E11) and at least one photovoltaic surface (P) comprising an undulating rigid structure (S) covered with flexible photovoltaic panels (F), the wind turbine (E) being disposed above the flexible photovoltaic panels (F) with the blade tips (E11) passing close to the flexible photovoltaic panels (F) in order to deter birds and clean the flexible photovoltaic panels (F).
