Physicists in the Netherlands have built a heat engine that might be the tiniest ever created. Based on “piezoresistive” silicon, and smaller than a typical biological cell, the engine could find ...

As the world battles rising inflation, a cost-of-living crisis, climate change and more, it’s clear that the fossil-fueled status quo is not working. Fossil fuels may have seemed like the crutch we ...

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an ...

Airthium, a clean technology company based in Austin, Texas, has developed an innovative heat engine designed to replace fossil fuels and decarbonize industrial heat and power generation. The company ...

Physicists successfully created a working heat engine that consists of only one atom. When built on a larger scale, the output of this single-atom engine could replicate the one from a car engine.
