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

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. cyclopentane), a potent greenhouse gas (e.g. CFCs, or chlorofluorocarbons), or toxic (e.g. A at 115 VAC, or 586 W, which works out to a COP of 3.0
