In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

Composite Flywheel Energy Storage

Current research in flywheel energy storage in the Composites Manufacturing Technology Center at Penn State University is aimed at developing a cost effective manufacturing and fabrication process for advanced composite rotors. Composites are desirable materials for flywheels due to their light weight and high strength. Lightness in high speed rotors is good from two standpoints: the ultra-low friction bearing assemblies are less costly and the inertial loading which causes stress in the material at high rotational speeds is minimized. High strength is needed to achieve maximum rotational speed. Therefore, advanced composite rotors enable the storage of greater amounts of energy on a per unit weight or volume basis, in comparison with other materials. Furthermore, fiber reinforced composite rotors have been shown to fail in a less destructive manner than metallic rotors -- an important factor for safety reasons. Flywheels offer the potential of higher energy and power density in comparison with conventional energy storage devices such as chemical batteries. There is much interest in flywheels for energy storage in applications as diverse as satellites, stationary diurnal storage, uninterruptable power supplies, and hybrid electric vehicles.
