A method where a propeller is set into locomotion relative to a medium at least partially surrounding the propeller. An actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and the propeller converts its rotational movement into locomotion relative to the medium. The aspect ratio of at least one cross-section of the propeller is three or more. Also a helical or modifiedly helical propeller for converting rotational movement of the propeller into locomotion of the propeller relative to a medium at least partially surrounding the propeller, where the aspect ratio of at least one cross section of the propeller is three or more. And a method of producing a propeller, including the step of providing a plate extending along the helical axis, where the aspect ratio of at least one cross section of the plate is three or more.
A method in which a propeller is set into locomotion relative to a medium in a human body which at least partially surrounds the propeller, wherein an actuator induces a rotation of the propeller relative to the medium and about a rotational axis of the propeller, and wherein the propeller converts its rotational movement into locomotion of the propeller relative to the medium, wherein an aspect ratio of at least one cross section of the propeller, which cross section is a cross section related to the propeller's rotational axis, is 3 or more, and on at least one cross section, a rotational center is inside the cross section of the propeller.
