It's important to keep in mind that the combustion process occurs in a very brief period of time. Due to a variety of conditions that include mixture density, homogeneity, temperature, fuel ...

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 ...

Over on his YouTube channel [Tom Stanton] shows us how to build a Stirling Engine for a bike. A Stirling Engine is a heat engine, powered by the expansion and contraction of a working fluid (such as ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

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 ...

For more than 100 years, the internal combustion engine (ICE) has been the mechanism of choice for vehicles of all shapes and sizes. Across all configurations, the principle is the same: a mix of fuel ...

The Lockheed Martin F-35 Lightning II is one of the few fifth-generation military aircraft currently in operation. Compared with all the others still flying in the world, it’s a true junior, having ...

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 ...
