The new SR20-D2 and SR22 pyranometers are made for solar radiation measurement experts, respectively in PV monitoring systems and climatological networks. SR20-D2 is highly accurate and offers two types of irradiance outputs: digital via Modbus RTU and analogue 4-20 mA. SR22 pyranometer has high-quality quartz domes, with a spectral range covering the full solar spectrum.
Megan Treacy for TreeHugger: A new technology developed by University of Nebraska-Lincoln electrical engineering doctoral student Jie Cheng solves both of those problems by harnessing the excess wind energy usually wasted as spillage and storing it for use when wind speeds dip, making wind turbines more efficient and consistent. Cheng's system converts and directs the extra wind energy to an air compression tank, where the energy is stored until wind speeds dip below the maximum capacity. Using a rotary vane machine that is connected between the turbine's gearbox and generator, excess energy is diverted and stored in the air compression tank. When the wind dies down, the tank then kicks in and reverses airflow back to the rotary vane machine to generate electricity. In a recent study of his prototype, Cheng found that a 250-kW system would produce an additional 3,830 kWh of electricity per week or an additional 16,400 kWh per month based on historical wind data from Springview, Nebraska. That extra electricity is about 18 times the monthly energy use of a typical American household. Cont'd...
