The depletion of energy resources poses a significant threat to the development of human society. Specifically, a considerable amount of low-grade heat (LGH), typically below 100°C, is currently being ...

UC Davis engineers have invented a Stirling engine that captures Earth’s escaping heat to generate power from the night sky.

Scientists are learning how to turn the chill of outer space into a quiet source of electricity, using the night sky itself as a heat sink. By carefully managing how surfaces shed heat after dark, ...

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 ...

Jet engines are relatively simple in their basic design, but advancements in gas turbine engine technology have mostly done away with the cool-looking bucket-type reverse thrust systems. These thrust ...

MIT says its new solid-state thermophotovoltaic heat engine can harvest more energy from heat than the average steam turbine, at a fraction of the cost and using no moving parts. Huge implications for ...
