Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

This configuration uses gas-foil bearings and includes a small turbine (red). In its final configuration, the TAC uses gas foil bearings, a high speed permanent magnet motor/alternator and labyrinth gas seals to reduce the rotor cavity pressure. Turbo-alternator-shaft design for the SNL S-CO 2 test loop. Source: Wright et al.

A closer look at why heat pumps are dominating EV HVAC systems

Charged EVs

cyclopentane), a potent greenhouse gas (e.g. The compressible-gas heat pump gets all the action because it is the most efficient (i.e. In an EV, while using the HVAC won’t detract from the maximum output of the traction motor, it does still demand energy from the battery, so there will be a hit to range.
