For anyone wanting to do something, open source makes it easier for you to get started, for creative ideas to flourish and for difficult problems to be solved by collaborating with others. I talk with Joshua Pearce about his new book, "Create, Share and Save Money Using Open Source Projects." Joshua is a professor of materials science and electrical engineering at Michigan Tech University where he directs the Michigan Tech Open Sustainability Technology Lab - acronym MOST. He's also the editor of Hardware X, a peer-reviewed journal dedicated to open source scientific hardware.
