  • Finite element analysis of turbine generator rotor winding shorted turns

    Abstract Online magnetic flux monitoring via permanently installed air-gap flux probes is a well- established technology to determine the presence of shorted turns in a turbine generator rotor winding. Flux measurements are normally performed using flux probes installed in the machine air gap (on a stator wedge) and connected to portable or permanently installed instruments. In this ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Eco-Brella: prototype development of the umbrella as harvester of solar and wind energies

    The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable of harvesting ...

  • Diffuse reflectance spectroscopy using a handheld FTIR

    As has been previously discussed (1), FTIR spectroscopy is emerging as a technique that can be effectively used for applications and/or in locations that heretofore would be considered too demanding. The development of portable FTIRs, and more recently handheld FTIRs, is significant because it enables this powerful analytical technique to solve problems for a whole range of new applications, both ...


  • Introducing The RNRG Goalpost Boom

    We are happy to introduce a new goalpost mounting solution for installing redundant class 1 anemometers. This new boom, designed specifically for use with our 80m XHD TallTower, positions anemometer cups at exactly 80 m above ground level—2.5 m away from each other—and 1.99 m ...
