A device 10 for installation within or on a structure for transferring kinetic energy from a load moving across the structure to a pneumatic or hydraulic system 3 for harvesting this wasted energy. A rocker having an upper surface for passage of the load is pivotally or slidably mounted in a cradle, the cradle housing at least one pneumatic or hydraulic pipe disposed between the rocker and the cradle.

A system manages the reactions of fluids to their changes in their environment in order to convert these reactions into energy thereby harvesting the same while protecting the device against destruction or malfunction when the environmental conditions exceed predefined thresholds.

A system for converting vehicular kinetic energy into electricity includes at least one on-road energy collection sub-system and a transmission sub-system. The on-road energy collection sub-system includes at least one flap lever configured to pivot in response to a vehicle driving thereover, and at least one flap lever shaft coupled to the flap lever such that the pivoting of the flap lever drives movement (rotational and/or translational) of the flap lever shaft. At least one output shaft is coupled to the flap lever shaft such that the output shaft is driven to rotate to provide a unidirectional rotational output in response to the movement of the flap lever shaft. The transmission sub-system is configured to receive the unidirectional rotational output from the output shaft as a rotational input and to selectively modify the rotational input for transmission to a flywheel sub-system.

Among other things, an integrated portable energy conversion mat is to be installed at a pavement surface over which a car or truck is to pass. The mat has a width at least as wide as the distance between the outermost edges of the treads of the tires located at an axle of the car or truck. The mat has a top surface over which the tires of the car or truck are to pass. The mat includes a sealed enclosed space housing and energy conversion system. The energy conversion system includes two sets of channels that extend along a length of the mat and contain hydraulic fluid under pressure. An energy converter converts energy carried by the hydraulic fluid in response to the tires of the car or truck passing over the top surface into electrical energy. An electrical port is coupled to the energy converter and exposed at an outer surface of the mat. The two sets of channels are spaced apart across the width of the mat by a distance that corresponds to the distance between the treads of the tires located at an axle of the car or truck. The energy converter is located within the sealed enclosed space of the mat and in the portion of the mat that is between the two sets of channels.

A roadways power and energy mechanical road captures and harnesses energies imparted to the roadway by the tires of vehicles driven on the roadway. Pistons, crank shafts, and additional mechanical interconnections mounted in a housing installed beneath the surface of the roadway are connected to generators adjacent to the roadway to convert linear mechanical motion to rotational mechanical motion to generate electrical power.

An energy harvesting system (100) for harvesting energy from vehicles travelling on a road (102). The system (100) includes a plurality of flexible hoses (104) which are embedded in a road overlay (106). Each hose (104) holds a hydraulic fluid, e.g. water, such that, when a vehicle wheel (108) passes over the hose (104), the fluid is displaced. The system (100) further comprises a plurality of double-acting hydraulic fluid cylinders (109) which are in fluid flow communication with the fluid in the hoses (104) and are configured to convert pressure applied to the fluid into rotary motion which drives an electrical generator. One hose is connected to each end of the cylinder (109) to drive it in opposite directions to induce linear reciprocating motion which is converted to rotary motion by way of a mechanical drivetrain. Due to the double action, it drives at least two drive shafts simultaneously.

A road-based energy harvesting system that converts kinetic energy from passing traffic to electricity using a hydraulic motor, powered from a pressurised fluid in a closed circuit, which drives an alternator. The system may have two platforms, operating in a see-saw fashion to transfer torque to compress at least one piston in a cylinder. During a first half cycle the piston performs a high-pressure stroke with a first working hydraulic fluid and during the second half cycle the at least one piston performs a low-pressure stroke with a second working fluid, such as air. The system may include a vehicle recognition system for detecting the mass of an oncoming vehicle and varies the resistance of at least the first piston in a cylinder to optimise energy extraction.

An electric power generating device includes a hydraulic power unit in fluid communication with hydraulic fluid and a hydraulic piston, the hydraulic piston creating compressed air to drive a pneumatic piston, the pneumatic piston driving a pneumatic motor, the pneumatic motor driving an electric generator/alternator. The electric power generating device can further include a canister air exchange comprising a small diameter pipe wrapped perpendicular inside a small section of larger pipe which creates a pressure induced spin movement to drive an electric generator/alternator.

A hydraulic electric power generation system for roadway installation has a plurality of fluid-filled compressible pump channels positioned for compression by a vehicle to drive the fluid in a channel outwardly through outlet sides of the channels. The channels are contained in a mat adapted for positioning of a roadway surface in a manner such that the channels are compressed by the tires of vehicles travelling on the roadway. An outlet manifold collected the fluid driven out through the outlet sides of the channels and directs it to through piping to a hydraulic motor and coupled electric generator. The fluid exiting from the motor passes to a sump, from which it can be returned to a mat manifold at inlet sides of the channels. The channels are provided with one-way valves to prevent backflow.
