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

Research focuses on supercritical carbon dioxide (S-CO 2 ) Brayton-cycle turbines, which typically would be used for bulk thermal and nuclear generation of electricity, including next-generation power reactors. The Brayton cycle could yield 20 MW of electricity from a package with a volume as small as four cubic meters.

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

Charged EVs

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. If you want to heat up a space that is cold, there are a number of options, from burning a fuel to directly converting electricity into heat (i.e.
