Professor Antoni K. Oppenheim was more than a scientist—he was a visionary who reshaped the field of combustion engineering. 

While others accepted the limitations of the 19th-century technology, the Otto cycle engine, Oppenheim saw its flaws such as::

• Hot flame fronts, which slowly move through the combustion chamber and are the source of harmful NOx emissions, and (image 2) 

• Quenching layers: The cold surfaces inside the combustion chamber where unburned hydrocarbons and CO form. (image 3)

Jim Duncalf has devoted his life to protecting the Earth and advancing energy innovation. From the start of his career, he has worked to develop clean, safe, and practical ways to power our modern world. As spokesperson for the Illinois Department of Energy (1976–1980), he spoke at universities, business forums, and expos, introducing pioneering technologies that reduced energy use and reshaped public understanding of energy efficiency.

Today, Jim continues to challenge laws that grant monopolies to large utilities—especially in transportation. He argues that reliance on coal, petroleum, nuclear, wind, solar, and hydro comes with hidden costs: devastating ecosystems, polluting the air, and releasing toxins that claim millions of lives.

At the center of his advocacy is Kamtech’s On Board Electric (OBE) technology—a truly zero-emission breakthrough. When powered by additive-free fuel, its exhaust is composed only of water vapor and carbon dioxide, the very foundation of life.

For more than two decades, Jim has been a passionate voice for bringing this innovation into the mainstream, pushing for a future of mobility that is efficient, clean, and economical. His vision is clear: a world where progress no longer comes at the expense of the planet.

Phạm Duy Tùng: Driving Rad Cam Forward A graduate of Ho Chi Minh City University of Technology and Education, Tùng was key in keeping Rad Cam rooted in Vietnam. With hands‑on engine experience, translation skills, and persistence, he guided early prototypes and helped avoid costly mistakes.  

The results of those trials showed a plus for design but a minus for several materials we used. Our experience was much like how Thomas Edison put it. "We did not fail. We just found 10,000 ways that don't work!"  

His dedication and persistence ensured Kamtech OBE 1 survived challenges and continued until we solved virtually all remaining problems.

Professor Hung: Advancing OBE 1  In 2026, Professor Nguyen Dinh Hung joined the Rad Cam project, bringing expertise in engine control, fuel injection, and HCCI. He introduced an innovative air‑assist system, leading to a new patent. His work strengthens OBE 1’s efficiency and sustainability, while training future engineers to carry this breakthrough forward.
