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 ...

Researchers at Rice University have found a new way to improve a key element of thermophotovoltaic (TPV) systems, which convert heat into electricity via light. Using an unconventional approach ...

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 ...
