Talking with wind energy engineer Fort Felker about turbine manufacturing is like taking a breath of fresh air. A hearty fellow with a big voice and a slight southern drawl, he doesn't come across as someone who holds a patent in winglet technology, a PhD in Mechanical Engineering from Stanford University and was instrumental in the design of the modern wind turbine. He comes across as someone who believes in the power that renewable energy has to change the world – and the important role that solid mechanical design and analysis tools play in order to make that happen.
