Grad Student Updates Century-Old Math Equation to Improve Wind Turbine Efficiency

Grad Student Updates Century-Old Math Equation to Improve Wind Turbine Efficiency

Divya Tyagi, a graduate student at Pennsylvania State University (Penn State), has revised a 100-year-old math equation to improve modeling for wind turbine efficiency. Tyagi used a century-old equation originally developed by aerodynamicist Hermann Glauert. Glauert created the equation to find the maximum power coefficient to determine optimum rotating actuator disk performance, and this initial […]

    Decarbonization Improves Most Countries’ Energy Security: Study

    Decarbonization Improves Most Countries’ Energy Security: Study

    Transitioning to clean energy and away from fossil fuels by 2060 would reduce trade risks and improve energy security for most nations, a new study has found. Rare earth minerals like lithium, copper, nickel and cobalt are “prized materials” for corporations and countries rushing to secure supplies for clean energy systems. The most concentrated natural […]
