Study finds reduction of low-frequency noise from transition to electric buses improved residents’ health

Green Car Congress

The health of residents living alongside a bus route in Gothenburg, Sweden, improved when hybrid buses were replaced by buses fully powered by electricity. Previous noise-level measurements had indicated that disturbance from low-frequency noise in indoor environments was present in the residential area. —Kerstin Persson Waye.

New smelting reduction process to recover Co, Ni, Mn, and Li simultaneously from Li-ion batteries

Green Car Congress

A team from metals research institute SWERIM in Sweden reports on a smelting reduction process to recover cobalt, nickel, manganese and lithium simultaneously from spent Li-ion batteries. To provide a better reference for the industrial implementation, the proposed smelting process needs to be demonstrated on a pilot scale.

What Is a Heat Pump?

Cars That Think

That liquid is now hotter than it started out, so some of the heat it holds flows easily (likely with the help of a fan) into the surrounding environment—be that the great outdoors or just the rest of your kitchen. These are referred to as water-source heat pumps. They then compress that gas, which condenses back into liquid form.

How Generative AI Helped Me Imagine a Better Robot

Cars That Think

The phrase refers to how the AI software iterates through design mutations and converges on high-performing designs. In these kinds of engineering environments, co-designing with generative AI, high-quality, structured data, and well-studied parameters can clearly lead to more creative and more effective new designs.
