The annual Columbia Gorge Wind Challenge will be at the Fort Dalles Readiness Center on Saturday. Over 50 middle and high school teams will take part in the event. Google’s Dave Karlson says those teams will be given a box of parts when they arrive and will make working wind turbines. There will also be a STEM fair featuring hands-on exhibits from OMSI, Gorge Makerspace, Bonneville Power Administration, and more. The Challenge will run from 8:30 a.m. to 4 p.m. Saturday at the Fort Dalles Readiness Center. It is put on by Google, the Gorge Technology Alliance, and Columbia Gorge Community College.
