This is the third year the GTA is helping host the Gorge Wind Challenge with partners Google and Columbia Gorge Community College. In this one-day event on March 17, middle and high-school teams compete to build the best wind turbine. It’s a remarkable event with no advance preparation needed from the students and everything – materials, lunch, t-shirt – provided for free. Volunteers are needed to help guide the teams through the turbine build. Training is provided. More info and registration here.
