An electricity generating wind turbine system for installation on roofs of urban homes has been designed by UK energy consultant Derek Taylor (Wind Power Monthly, Vol 11, No 7). Developed by Taylor's company Altechnica, this roof wind energy system is like a roof venting system in appearance and takes advantage of the prevailing wind direction. "it takes advantage of the airfoil type of effect these roofs have on air flow passing over thern,"says Taylor. According to Taylor, in windy areas the system should meet the electricity requirements of a low energy house.
