[en] Within the frame of the Darwin program, the European Space Agency and the European Southern Observatory (ESO) intend to build a ground-based technology demonstrator called Darwin-GENIE, using the Very Large Telescope Interferometer (VLTI). The main objective of GENIE is to gain experience in the manufacture and operation of a nulling interferometer representative of the ESA IRSI-Darwin space mission. GENIE will prepare the Darwin science programme through a systematic search for exo-zodiacal dust clouds around Darwin candidate targets. GENIE also aims to perform Darwin related science including the detection of low-mass companions (if possible, hot Jupiters) around nearby stars. The prospective performances of some candidate configurations are presented in this paper.
