A new design with no moving parts converts heat to electricity more efficiently than a steam turbine and could lead to a fully decarbonized power grid. Engineers at MIT and the National Renewable ...

Engineers at the University of California, Davis, have built a small device that produces mechanical power at night by exploiting the contrast between ambient warmth and the extreme cold of outer ...

Heat engines are thermodynamic physical systems that convert heat energy into mechanical work by exploiting a temperature difference between a high-temperature heat source and a low-temperature heat ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

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 ...
