This high-speed FESS stores 2.8 kWh energy, and can keep a 100-W light on for 24 hours. Some FESS design considerations such as cooling system, vacuum pump, and housing will be simplified since the ISS is situated in a vacuum space. In addition to storing energy, the flywheel in the ISS can be used in navigation.
