Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

This startup is about to install bladeless rooftop wind turbines on box buildings

Baua Electric

Aeromine, launched in 2022, makes compact 50 kW or larger “wind harvesting platforms” that it mounts on the edge of a building’s roof. The rooftop wind units, which have no external moving parts or blades, capture wind flowing up and over the building and convert it into onsite electricity. Specs are here.) Get started here. –ad*
