A Penn State student refined a century-old math problem, originally published in 1935, that determines the optimal aerodynamic performance of a wind turbine. The student's work improves upon the ...

In fact, the turbines were able to reach an efficiency of 53%, which is just shy of Betz's Law, a theorem that says no wind turbine would be able to convert more than about 59.3% of wind energy into ...

On a quiet afternoon in University Park, Pennsylvania, aerospace engineering student Divya Tyagi (22) sat buried in equations that had defeated generations of aerodynamicists. The puzzle, first posed ...

We haven't seen a floating offshore wind turbine like this before. Touchwind claims its innovative single-blade turbines will solve several problems to drive down cost and downtime, using a single, ...

Divya Tyagi, an Indian-origin engineering student at Pennsylvania State University, has simplified a century-old math problem ...

Wind energy infrastructure doesn’t produce power if the air isn’t moving, and solar doesn’t generate power if the sun’s not out. But that doesn’t mean that either source of energy is "worthless" ...

Editor’s Note: Call to Earth is a CNN editorial series committed to reporting on the environmental challenges facing our planet, together with the solutions. Rolex’s Perpetual Planet Initiative has ...
