Wind Turbines on CO2 Neutral Luminaries in Urban Areas

The objectives of the project are to investigate the potential of combining wind energy and solar energy to power a luminary and to design and construct a prototype. In the poster, especially the wind energy part of the concept is in focus. The basis of the design of the wind turbine is made by Mertens [1] and Beller [2]. In the present work, a simulation of three hybrid street luminaries (lamps) comprizing wind turbines is presented. The luminaries are: Green Power with a Savonius (left), United Electricity with a horizontal-axis (center), and Sanya with a helical H-rotor (right) turbines. The simulated luminaries are also equipped with photovoltaic panels, batteries and LEDs, detailed investigation of which is outside the scope of the present work. Analysis of the turbines’ performance based on producer-supplied power curves is presented together with an estimation of the wind climate in Copenhagen. A new twisted Savonius rotor is proposed for a luminary being designed for Copenhagen within the “Development of CO2 neutral urban luminary” project.
