LA Metro is spending billions to upgrade its rail transit system. On projects like extending the Purple Line to the Westside, it wants to harness green energy. But a project to capture wind on a Red Line train platform has experts in physics scratching their heads. For KCRW's Independent Producer Project, Roger Rudick reports that going green may not be so black and white.
Metro officials say the turbine generated enough electricity to power 12 homes, but they're still evaluating the technology. There are photos of the Metro turbine on the WWLA blog.
