Embodiment Construction

[0168] figure 1 An exemplary system 100 is shown that may be part of a larger system (not shown) for storing and releasing energy. The subsequent figures will illustrate the application of embodiments of the invention to such a system. figure 1 The system 100 shown in FIG. 2 features an assembly 101 for compressing and expanding a gas. Expansion / compression assembly 101 may include or consist essentially of one or more separate devices for expanding or compressing gas (e.g., a turbine or cylinder assembly, each of which may include a movable boundary mechanism ) or graded series of these devices, and figure 1 Auxiliary equipment (e.g. valves) not expressly shown.

[0169] A motor / generator 102 (eg, a rotary or linear motor) is physically connected to the expansion / compression assembly 101 (eg, via a hydraulic pump, piston shaft, or mechanical crankshaft). The motor / generator 102 can be electrically connected to figure 1 Sources and / or sinks of electrical energy not ex...
