MPa enable the system to operate with very high thermal efficiency, exceeding even those of a large coal-generated power plant and nearly twice as efficient as that of a gasoline engine (about 25%). This configuration uses gas-foil bearings and includes a small turbine (red). Turbo-alternator-shaft design for the SNL S-CO 2 test loop.
