Abstract: Power generating devices and systems that include devices, apparatus, systems and methods with a turbine assembly disposed in a recess under the road surface as the sustainable actuating mechanism include a pivoting treadle plate upon which is mounted a counterweight wherein the force of gravity raises load-bearing pivoting treadle plate that spans a recess below the roadway to a slope relative to roadways and also utilizes the movement of wheels of automobiles driving over the upper surface of the angled pivoting treadle plates or flaps with hinges to drive down the treadle plates to be substantially level and flush with the roadway as kinetic power to push down a downshaft, Pitman arm and crank to convert linear force to rotational energy to spin electric generators to generate electricity.

Abstract: An expandable and retractable wheel assembly in accordance with one or more embodiments includes a hub structure having a circular periphery and a rim expandable in circumference from a retracted circular position to one or more expanded circular positions. The rim engages and is supported by the circular periphery of the hub structure when in the retracted position. A plurality of linear actuators is attached to and supported by the hub structure. Each linear actuator includes a piston rod and a drive system for moving the piston rod from a retracted position to one or more extended positions, wherein a distal end of the piston rod engages and moves the rim when the piston rod is extended and also supports the rim in the one or more expanded rim positions.

Abstract: A transportation vehicle and methods for transporting persons, robots or cargo, and more particularly motorized vehicles, and methods for transporting over surfaces, including surfaces such as floors, roads, paths and sidewalks, and surfaces having obstacles or inclined surfaces and for enabling the ascending or descending of stairs without tilting while supporting a user or a load on a frame. The vehicle uses horizontal extending and retracting rods and vertical extending and retracting rods to pass over an obstacle or ascend or descend stairs. The horizontal extending and retracting rods are used as mechanisms to move the first set of ground contacting modules located to the fore of the vehicle or the last set of ground contacting modules located to the aft of the vehicle in a fore-aft plane to pass over an obstacle or to position the first set or last set of ground contacting modules upon a stair to be used for ascending and descending stairs.
