Looking at Atmospheric Stability to Predict Wind Power

Power generated by a wind turbine largely depends on wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power. Two researchers say that this variable power can be predicted by looking at atmospheric stability.

Superconducting Current Limiter

A new superconducting current limiter based on YBCO strip conductors has been installed at a power plant. At the Boxberg power plant of the Swedish company Vattenfall, the current limiter protects the grid for own consumption that is designed for 12,000 volts and 800 amperes against damage due to short circuits and voltage peaks.

Sunflower-Inspired Pattern Increases Concentrated Solar Efficiency

There are only a handful of concentrated solar power (CSP) plants in the world. The technology could potentially generate enough renewable energy to power the entire U.S., provided that land and sunlight are in ample supply. Researchers have now come up with a design that reduces the amount of land required to build a CSP plant, while increasing the amount of sunlight its mirrors collect.

Pollution Reducer & Heat Generator

New technology from North Carolina State University and West Virginia University can reduce air pollutant emissions from some chicken and swine barns while also reducing their energy use by recovering and possibly generating heat. A proof-of-concept unit incorporates a biofilter and a heat exchanger to reduce ammonia emissions.
