By now, Blacksburg residents and commuters who travel Main Street will have noted an egg beater-like apparatus on a pole in front of the YMCA. The raising of the pole for the mini wind-turbine on April 19 was a major milestone in what has turned out to be a year-long effort by Virginia Tech students, faculty members, and staff, and community volunteers to build a wind and solar demonstration site and education center at the YMCA center at 1000 North Main Street.
