In 2008, Robert Steinhaus retired after 34 years working in nuclear research at the Lawrence Livermore National Labs. During his career, he worked on the U.S. nuclear weapons program and on magnetic mirrors.  Mr. Steinhaus has been advocating for fusion and fission concepts for several years, as part of the Thorium Energy Alliance and The Fusion Energy League.  In our interview we talk about his LLNL career and the links between fusion research and its connections to U.S. leadership in nuclear research.
