Abstract
A coaxial shaft is coupled to a platform that rolls or glides on a track. The coaxial shaft has two components which rotate in opposite directions from each other so that two rotation members can be rotated in opposite directions (clockwise and counter-clockwise). This rotation generates outward forces in each rotational member, which are summed so that the force components perpendicular to the track cancel each other out, and the force components parallel to the track constructively sum to produce and oscillation of the platform along the track. This oscillation can be used by a linear generator to produce a time-varying voltage output.

An apparatus for converting rotation motion to linear motion, comprising:
- a base having a pair of rails that are parallel to each other, a longitudinal axis defined midway between the rails and parallel to the rails;
- a platform mounted on the pair of rails and configured to roll freely along the pair of rails;
- a coaxial shaft extending from the platform centered over the longitudinal axis, and having a first portion that rotates in a first direction and a second portion that extends above the first portion that rotates in a second direction that is opposite of the first direction;
- a first boom coupled to the first portion of the coaxial shaft and having a first boom mass;
- a second boom coupled to the second portion of the coaxial shaft and having a second boom mass;
- and
- wherein, upon applying a rotational drive to the coaxial shaft, the first boom is rotated about the coaxial shaft in the first direction and the second boom is rotated about the coaxial shaft in the second direction in synchronization such that rotation of the first boom and rotation of the second boom meet on the longitudinal axis, and wherein rotation of the first and second booms causes linear oscillation of the platform on the pair of rails.
