Austin’s new development at the site of the old Robert Mueller airport includes a small solar farm consisting of fifteen of these lovely blue “solar sunflower” collectors, designed by Cambridge’s Harries/Héder Collaborative, whose concept was selected from a pool of 37 applicants to Austin’s Art in Public Places program. Details of the project are available here. The collectors, which have been installed but aren’t yet active, will collect energy during the day and release it at night as light for the nearby hike-and-bike trail.
