Massachusetts Institute of Technology engineers have developed a heat engine with no moving parts that is more efficient than a steam turbine. The researchers say the design could someday enable a fully decarbonized power grid. Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency – a performance better than […]

For seven years Ontario’s inventor Ian Marnoch has been developing a new kind of “heat engine” that he says can generate electricity more economically from lower-grade heat. While that heat could come from anywhere: the ground, the sun, or an industrial waste process, geothermal needs a much better temperature spread to achieve wide ranging use. […]
