Here is our final installment of Maker Pioneers featuring inventors, entrepreneurs, and makers who are dreaming up clever solutions to today’s energy and environmental problems. In this video, we meet Kurt Fleischer. Kurt is a senior research scientist at Pixar, where he worked on building filmmaking software and directly on such films as Cars and WALL-E, before becoming a member of their research team. On his off time, he likes to apply his engineering skills to work on projects with his daughter, Lena, such as the Water Totter seen in this video. He used this project, which turns an old-style seesaw into a water pump, as an opportunity to teach Lena about concepts in engineering, conservation, energy generation, and a few life lessons.
