Fantasy and science fiction are both involved in the process of innovation in techno-scientific societies. Long regarded as a hindrance to rationality, and to science, science fiction has become the object of praise in recent decades.  Innovative organizations use science fiction to stimulate the creativity of their teams, and more and more entrepreneurs are using its influence to develop innovation. Scientific practice relies in part on an imaginary dimension. The mapping of the technical imagination of science fiction has become an important strategic issue, as has its patentability.  The conquest of space, the construction of cyberspace and virtual reality, biotechnologies and nanotechnologies are all at the center of futuristic fictions that participate in scientific speeches and discoveries.
