The system has an air turbine (4) arranged along an air stream produced by vehicle, where the turbine drives an energy generator (2) i.e. alternator, in rotation. The turbine is connected to the generator by a mechanical movement drive train (20). The drive train between the turbine and the generator comprises a variation device for performing continuous variation of speed ratio. The drive train includes a variable gauge length pulley (24), which clasps a driving belt (26) of the generator. |
