2. Flywheel energy storage - Wikipedia

   en.wikipedia.org/wiki/Flywheel_energy_storage

   NASA G2 flywheel. Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy.When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of the ...

3. Kinetic energy recovery system - Wikipedia

   en.wikipedia.org/wiki/Kinetic_energy_recovery_system

   KERS is also possible on a bicycle. The EPA, working with students from the University of Michigan, developed the hydraulic Regenerative Brake Launch Assist (RBLA) [30] This has also been demonstrated by mounting a flywheel on a bike frame and connecting it with a CVT to the back wheel. By shifting the gear, 20% of the kinetic energy can be ...

4. Bottle dynamo - Wikipedia

   en.wikipedia.org/wiki/Bottle_dynamo

   Bottle dynamo mounted on a bicycle. Dismantled bottle dynamo. Left: Housing with internal permanent magnet rotating through the friction wheel. Right: Induction coil. A bottle dynamo or sidewall dynamo is a small electrical generator for bicycles employed to power a bicycle's lights.

5. Diesel rotary uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Diesel_rotary...

   Diesel rotary uninterruptible power supply devices (DRUPS) combine the functionality of a battery-powered or flywheel-powered UPS and a diesel generator. When mains electricity supply is within specification, an electrical generator with a mass functions as motor to store kinetic energy in an electro-mechanical flywheel. When mains electricity ...

6. Regenerative braking - Wikipedia

   en.wikipedia.org/wiki/Regenerative_braking

   On electric bicycles, regenerative braking can be used in principle. However, as of 2024 it is rarely used on bicycles, mainly because it requires a direct-drive hub motor (while many bicycles use a mid-drive motor which drives the chain), and because it cannot be combined with a freewheel mechanism. Also, the amount of energy regenerated is ...

7. Flywheel storage power system - Wikipedia

   en.wikipedia.org/wiki/Flywheel_storage_power_system

   A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.

   Between a pandemic-fueled bike boom and growing interest in electric transport options, demand for electric bicycles, or e-bikes, has been picking up speed.

9. Flywheel - Wikipedia

   en.wikipedia.org/wiki/Flywheel

   The flywheel material with the highest specific tensile strength will yield the highest energy storage per unit mass. This is one reason why carbon fiber is a material of interest. For a given design the stored energy is proportional to the hoop stress and the volume. [citation needed] An electric motor-powered flywheel is common in practice.
