Electrical “wand” extinguishes fires

A 200-year-old observation that electricity can affect the shape of flames is being revisited with an experimental device that uses an electric field projected from a probe to rapidly suppress flames. The scientists behind the development, who presented their findings at the 241st National Meeting of the American Chemical Society, say that the discovery could […]

Novel CO2 turbine promises leap in generator efficiency

Turbines that utilize supercritical carbon dioxide (S-CO2) for the generation of electricity could deliver a huge 50 percent improvement in efficiency compared to steam turbines, say scientists from Sandia National Laboratories. Used for thermal and nuclear generation of electricity, the new Brayton cycle S-CO2turbines would replace steam-driven Rankine cycle turbines, which have a much lower […]
