A rotor system 10 for a vehicle 5 has at least two rotor axles 21 on side supports 50, about which rotate rotor vanes 30, which may be semi-circular or helical, in a direction of circulating airflow 40, 42 of rotor system 10. An axis of rotation of each rotor axle 21 is orientable horizontally and perpendicular to advancing airflow over vehicle 5 during forward motion. Rotor axles 21 are tiered and their axes of rotation are parallel. Rotor system 10 also has front and rear cowlings 52, 54 which direct air to circulate around obverse and reverse sides of rotor system 10. Rotor axles 21 may be connected to a generator. Each rotor axle 21 may have a plurality of vanes 30. Also claimed is a vehicle 5 with rotor system 10, which may be for land, air or water transport.
