A power generation mechanism includes a first movable member, a second movable member, a twisted coil spring, a power generator, and a housing. The first and second movable members are gears. First and second wound parts of the spring are wound around a first center shaft in opposite directions. Initial elastic energies ie1 and ie2 are respectively applied to the first and second wound parts, absolute values of ie2 and ie1 being equal. The second movable member is turnable by a force from outside the mechanism, engaging teeth of the first and second movable members together to turn the first movable member. With ie12 accumulating on the first wound part and with the teeth disengaged from each other, the first center shaft is turned in an opposite direction by ie12 to generate power in the power generator. Also, the first center shaft is turned by ie1 and ie2.

An epicyclic transmission gear and disk brake based regenerative braking device includes an epicyclic transmission unit to transfer braking energy through arrangement of sun gear and the planetary gears to a clock spring of a clock spring torque storage module. The device includes a disk brake unit that arrests the rotation of a sun-planetary gear assembly in the epicyclic transmission unit such that momentum available at the extended hub is transferred to a ring gear. The ring gear is connected to an inner casing of the clock spring torque storage module that charges the spring. The device includes a chassis unit that dissipates excess energy through spinning of an outer casing of the clock spring torque storage module by a spring calibration wheel that rides over a sinusoidal contoured surface of the outer casing.

A system for efficiently capturing the kinetic and/or potential energy of a moving vehicle includes an arc roller configured to move along an arcuate path upon impact by the moving vehicle, and a torsional spring configured to wind in response to the movement of the speed bump and, thereby, to store energy associated with the impact. The torsional spring may be configured to wind continually in response to the movement of another speed bump and, thereby, to store additional energy associated with the impact of the vehicle with the other speed bump. The system may include alternators or generators producing electricity from energy released from unwinding of the torsional spring. Electricity is further stored and utilized for onboard computing, traffic analytics, safety feature operating functions and communications.
