L'invention concerne un ensemble turbine de génération électrique comprenant un premier rotor qui peut tourner autour d'un axe de rotation sous l'action d'un fluide sous pression et un ou plusieurs aimants (13) disposés sur le premier rotor pour tourner avec celui-ci, et comprenant en outre un second rotor agencé de manière à tourner coaxialement au premier rotor par l'effet du fluide sous pression et des enroulements de bobine électrique (30) disposés sur le second rotor de manière à tourner conjointement avec celui-ci pour produire de l'électricité lorsque le premier rotor et le second rotor sont mis en rotation par le fluide sous pression dans des directions opposées.
