Abstract
This paper presents a new conceptual design of an efficient flywheel battery, designed from commercially available components. The basic idea is based on a possibility of using a spare wheel of a vehicle, or its steel or aluminium disc, as the gyroscope rotor at an early stage of rotor development. Even low rotation speeds accumulate sufficient amount of energy to accelerate a small vehicle in a city.

Summary
Flywheels have been used in smooth running rotated mechanisms. Heavy rotation stone wheels served as flywheels in original purely mechanical powertrains. In case of sufficient slowdown of the gyrobus, the traction electric engine worked as a generator mode and supplied the energy back into the flywheel. This means that already at that time a part of braking energy was recovered. A hybrid bus APTS Phileas from 2004 (Figure 2) can be mentioned as an example This low-floor three-car bus combines an internal combustion engine, electric engine and flywheel of a power of 300 kW facilitating to store energy up to 4 kWh. The flywheel accumulates the energy derived exclusively from braking recovery. This paper aims to present a new design of a flywheel battery based on common components of vehicles, which allows effective accumulating of energy for later re-use for vehicle acceleration
