The Front CoverThe Spinner Anemometer consists of three single-path ultrasonic anemometers mounted on the spinner – taking measurements while the turbine operates. Accelerometers are included so that the correct azimuth angle of the sensor in question can be determined. The device was invented and patented by Troels Friis Pedersen of Risø/Danish Technical University. On page 6 you can read the full article about the Spinner Anemometer. Publisher's NoteFeatures

The Front CoverOriginally, rotor blade inspections were mostly performed using a cherry picker, a service platform or a hydraulic crane; today, the most common way of performing these inspections effectively seems to be by rope descent (abseiling). Availon recently developed a drone for the inspection of rotor blades. The image on the cover shows the drone in action. On page 6 you can find the full article about this development.

The Front CoverSaphon Energy, a cleantech start-up based in Tunisia, has designed and developed a breakthrough technology that might revolutionise the wind energy sector. The new wind converter, named the Saphonian, is radically different from conventional turbines and is largely inspired from sailing boats. On page 7 you can read the full article about this new design. Publisher's NoteFeatures

The Front CoverWind tower access has traditionally required the use of cranes, bucket trucks, repelling teams or any combination of the three. Since Helical Robotics was founded in 2010, engineers at our Wisconsin-based company have created ways to streamline the work using remote-controlled, robotic devices that can scale a wind tower without any additional equipment. On page 34 you can read the full article. Publisher's NoteFeatures

The Front CoverThe Cleveland State University (CSU) wind tower system design concept focuses on the use of cylindrical wind-deflecting structures to increase wind speed as the stream of wind approaches the turbines. The image on the frontcover shows a picture of the first fully functional proposed wind tower, fabricated and installed on the rooftop of the Planet Service Building located on the CSU campus. On page 7 you are able to read the full article. Publisher's NoteFeatures

The Front CoverAn international movement against wind energy is maturing – across the globe today there exist over 1,000 anti-wind groups. The origin of the opposition is, in some instances, fossil fuel and nuclear backed interest groups and, at other times, local community members with genuine concern. The article on page 6 is the introduction to a series of topical columns which will dig into the causes of anti-wind sentiment and the maturing of opposition against wind energy development.

The Front CoverAs a result of the rapid growth in the offshore wind sector, the demand for spatial environmental data is constantly increasing. Traditional visual aerial survey methods suffer from reliability, safety and data quality drawbacks. These can be overcome by new digital methods, and in the article on page 6 the author discuss the application of these new technologies to offshore aerial bird and mammal surveys. The image on the cover is an example of a high-resolution image collected while on survey. (courtesy APEM Limited). Publisher's NoteFeatures
