Driving device utilizing inertia

The driving device utilizing inertia mainly contains a battery (10), a motor (20), a flywheel (30), a casing (40), a transmission box (50), a generator (60), a rectifier (70), and a charger (80). The flywheel (30) is mounted on a shaft and is housed in a vacuum chamber. The flywheel (30) freely spins by itself after being actuated by the motor (20). The flywheel (30)'s torque is then delivered to the transmission box (50) which in turn delivers the torque to drive a vehicle. On the other hand, the spinning flywheel (30) drives the generator (60) to produce electricity which is stored in the battery (10) series-connected to the generator (60) via the rectifier (70) and the charger (80). As such, the driving device is able to power the vehicle while the surplus energy is stored in the battery (10) for activating the motor (20) and turning the flywheel (30).
