Renewal Fuels, Inc. (OTC: RNWF), operating under the American Fusion brand, announced the appointment of Dr. John E. Brandenburg, Ph.D., as Chief Technology Officer of its wholly owned subsidiary Kepler Fusion Technologies, effective immediately. The move brings a seasoned plasma physicist with over four decades of experience in fusion energy and advanced propulsion to lead the development of the Texatron™ aneutronic fusion platform toward commercial-scale deployment.
Dr. Brandenburg’s career includes senior roles at Lawrence Livermore National Laboratory, Sandia National Laboratories, The Aerospace Corporation, the Florida Space Institute at Kennedy Space Center, and Orbital Technologies Corporation. He has held high-level U.S. government security clearances and contributed to sensitive defense and energy programs. His doctoral research at the University of California, Davis focused on field-reversed plasma layers, laying foundational knowledge for his work in fusion.
At Lawrence Livermore, Dr. Brandenburg researched magnetically confined thermonuclear fusion and performed LASNEX modeling on inertial confinement fusion pellet designs. At Sandia, he worked on relativistic electron beam physics. As Principal Scientist at The Aerospace Corporation, he directed the CMTX compact fusion propulsion experiment and supported national security programs, receiving a Letter of Commendation for contributions to the Cobra Judy Replacement Project.
Since February 2019, Dr. Brandenburg has served as lead scientist and technology architect at Kepler Aerospace Ltd. and Kepler Fusion Technologies, playing a central role in developing the Texatron™ compact toroidal fusion concept. Under his leadership, the Company has advanced theoretical research, proof-of-principle plasma confinement validation, and fusion-based clean energy systems development. He is the inventor or co-inventor on multiple U.S. patents covering plasma reactors, propulsion systems, and persistent ionization plasma generation, including U.S. Patent Nos. 6,205,769; 5,956,938; and 7,037,484.
Dr. Brandenburg is also the author of numerous peer-reviewed publications and the book The GEM Unification Theory: Extending the Standard Model to Include Gravitation. He is a Lifetime Member of the American Institute of Aeronautics and Astronautics.
Brent Nelson, CEO of Kepler Fusion Technologies, stated, “Dr. Brandenburg is one of the most accomplished plasma physicists working in fusion energy today. His decades of experience at premier national laboratories and his hands-on leadership in developing the Texatron™ platform make him uniquely qualified to guide our technology toward commercial deployment.” Richard Hawkins, Chairman and CEO of Renewal Fuels, Inc., added, “His career spans Lawrence Livermore, Sandia, Aerospace Corporation, multiple issued patents, and peer-reviewed scientific leadership. As we build an infrastructure-grade fusion platform, his technical vision and commercialization focus will be invaluable.”
