Abstract: A kinetic energy collector mechanism for generating electric power from passing vehicles, using a main axle connected to a flywheel, wherein the main axle is supported on two bearings and/or rollers, said main axle having a half-cylindrical support section for the vehicle wheels, and having attached on each end at least one flywheel that is mounted so as to transmit load in only one direction while it can rotate freely in the opposite direction, said main axle rotating in an angle ranging between 0° and 120°, preferably 45°, equivalent to 1/8th of a turn as the vehicle wheels pass over the half-cylindrical section of the main axle, thus driving the attached flywheel; wherein the main axle is returned to its original resting position by means of springs, then reapeating the rotational motion every time the main axle is driven by passing vehicle wheels; and wherein, the flywheel has enough driving force to rotate and drive a generator and its corresponding regulator by mechanical means that transmit the load to

Abstract: A rotary driven poster, for use in advertising, informative ends and other uses that include at least a main body with presenting faces that contain the advertising or informative composition of visual reception. The poster is mounted to a support with the body connected to a device that drives it with a uniform circular movement. The poster further includes a rotation center of the main body. The rotation center is connected to the support and possesses a radial arm on which a motor-reducer is mounted. The motor-reducer has an axis that supports a wheel. A ring-shaped piece is fixed to the structure of the main body and in concentric disposition with the rotation axis whose radius is equivalent to that of the radial arm. The ring-shaped piece has the support track of the wheel. The wheel is also the rotary driving means of the main body by way of the support track.
