Installation for power generation by means of vehicular traffic that can be located at floor level (2) of a vehicles traffic lane, wherein it has generator of electrical energy (5) modules, each of which includes: a set of mobile crossbar components (20) mounted over both sets (21a) of hydraulic cylinders (21), an hydraulic circuit (3), a linear hydraulic actuator (32), movement transformer mechanism (4) from straight swinging movement into a one-way rotating movement, and a generator (5) of electrical energy; each crossbar component (20) is moved by the own weight of the vehicles (7) crossing it, propelling a set of hydraulic cylinders (21) that, through the hydraulic circuit (3), are connected to the linear hydraulic actuator (32); this last one, through the movement transformer mechanism (4), propels the rotating movement of the electrical generator (5). When the wheel (70) of a vehicle (7) steps a mobile crossbar component (20), this last one moves downwards, so it propels the mobile arms (22) of the hydraulic cylinders (21). Once the descending cycle ends, the automatic repositioning of the crossbar component (20) takes places as a result of the floor elastic means (23).

An energy conversion assembly including an input shaft coupled to a first annular gear through a first direction limiting device configured to allow rotation of the first annular gear in a first direction and substantially inhibit rotation of the first annular gear in a second direction. The input shaft may be coupled to a second annular gear through a second direction limiting device configured to allow rotation of the second annular gear in the second direction and substantially inhibit rotation of the second annular gear in the first direction. The assembly may include a first transmitting gear engaged with the first annular gear, a second transmitting gear engaged with the second annular gear, a conversion gear operatively coupled to the second transmitting gear, and a transmitting shaft coupled to the first transmitting gear and the conversion gear.

A linear actuator (10) for use in a modular assembly of such actuators comprises an actuator body (11), a shaft (12) guided by the body to be displaceable relative thereto in the sense of tlte longitudinal axis (13) of the shaft and a drive motor enclosed in the body and operable to axially displace the shaft relative to the body in two mutually opposite directions. The body has two mutually opposite sides (15a, 15b) respectively lying in two substantial parallel spaced-apart planes, which each represent a reference plane for positioning the body side-by-side with the body of another such actuator, and a further side (17b) connecting the two mutually opposite sides and stepped to form a projection (18) receiving the shaft (12) with the axis (13) parallel to the two planes and a rebate (19) beside the projection to permit the body to interlock with the body of another such actuator at that further side. The projection (18) and rebate (19) are of substantially the same width in the sense of the spacing of the two planes and the shaft (12) is disposed substantially centrally of the projection (18) so that when the body (11) is interlocked with that of another such actuator the pitch of the shaft axes (13) is equal to that width.

A wave energy thermal storage type seawater thermoelectric power generation device which comprises a buoy-type energy capture system, a platform system and a mooring system. A whole friction liquid heating, thermal storage and power generation device is arranged inside a platform, which improves the adaptability of the whole system to the external environment. A flywheel and liquid friction heating method is adopted to generate heat more efficiently. Inner ratchets and pawls are used to control the movement of a flywheel so that the flywheel always rotates in one direction, and when the rotating speed of the flywheel exceeds that of the inner ratchets, the external wave energy cannot be transferred to the flywheel through the movement of the inner ratchets so as to limit the upper limit of the rotating speed of the flywheel and protect the safety of the flywheel system.

A two-stroke electromagnetic has a busbar, a magnetic field generator, a piston, a crankshaft, a connecting linkage, and a power source. The magnetic field generator may be a permanent magnet or a solenoid. The power source provides electric current to the busbar and the solenoid. The piston is positioned concentrically with the busbar, which produces a magnetic field upon receiving current flow from the power source. The magnetic field generator is connected atop the piston and oriented orthogonal to the magnetic field generated by current flow through the busbar, so that interaction of the two magnetic fields produces a downward force on the piston, which is connected to the crankshaft by the connecting linkage.

An exemplary actuator includes a motor, a transmission, and a support structure. The motor includes two torque sources that apply respective input torques to a rotor, which rotates about a rotation axis in response to a net input torque. The torque sources are arranged such that the input torques are additive, resulting in a vector-summated torque output. The torque sources also generate corresponding reactive torques that are applied to the first stator and the second stator. The transmission couples and constrains the first stator and the second stator such that rotational motion of one stator causes counter rotation of the other stator. Thus, the reactive torques are subtractive resulting a differential torque output. In some applications, the differential torque output is used to actuate a suspension of a vehicle. The actuator is also coupled to the vehicle via the support structure, which also reflects a reaction force or torque to actuate other subsystems (e.g., anti-dive, anti-squat).
