Engineers have developed a heat engine with no moving parts that is as efficient as a steam turbine. The design could someday enable a fully decarbonized power grid, researchers say. Engineers at MIT ...

Finding a new renewable source of cheap energy is the Holy Grail of our generation. Scientists are looking at cold fusion, hydrogen and bio-fuels, but maybe they should be looking backwards instead of ...

Sustainable municipal waste management solutions often involve waste-to-energy plants that can produce electricity while also providing steam to district heating systems. Efficient steam turbines are ...
