Windstar turbines are definitely on the right track, there are so many windy areas that could be exploited with the right equipment, underneath larger turbines on wind farms is just one of them, urban areas and the built environment is another. Kevin Wolf is ill-informed however when he states that Wind Harvest is the only company who have years of testing and international patents in the field of vertical axis wind turbines. In Europe there are a few other companies that have been working in this field for a number of years, most notably www.turby.nl, www.vweltd.com and www.quietrevolution.co.uk.
