Fish Schooling as a Basis for Vertical Axis Wind Turbine Farm Design

Most wind farms consist of horizontal axis wind turbines (HAWTs), but an alternative paradigm for wind energy extraction is found in vertical axis wind turbine (VAWT) designs. A single spatially-isolated VAWT has a significantly lower power coefficient.

Effects of Cerium Removal from Glass on Photovoltaic Module Performance and Stability

In recent years, better stabilizer formulations for ethylene vinyl-acetate have been developed, giving more confidence in the long-term stability of PV packaging materials. Because of this, some manufacturers have stopped using Ce-doped glass. National Renewable Energy Laboratory researchers studied Ce-free glass.
