Professor Antoni K Oppenheim

Luminary Of Rad Cam

Antoni was like the father of this project. He was determined not to let us fail in this challenge he gave us. When things looked insurmountable Toni would open up one of his large file cabinets and in a few minutes would find an answer. Then with the patience of a teacher, he would break down solutions or new concepts into understandable words. He never once said he did not have time to examine our progress. He was determined not to let us fail in this challenge he gave us. He always showed great enthusiasm for developing answers on how to improve the efficiency and performance of the Rad Cam engine concept. He was never short of new and innovative ideas. With quiet modesty, he was happy when we proved his concepts were viable. He is sadly missed.

Smokey Yunick

Mechanical Consultant

Smokey Yunick, was one of the most creative and knowledgeable engine designers perhaps in the world. He did consulting for various automakers during his years, most notably Hudson, Ford, and General Motors. Duncalf contacted him in 1991 shortly after taking on Professor Oppenheim's challenge to develop a truly "ideal engine." A few days after Duncalf explained Oppenheim's thoughts on better piston dynamics Smokey called with a recommended a constant acceleration cam profile. He explained that such a dynamic would put the least initial force on the engine and produce the longest dwell time at both ends of the stroke. His insights into lubrication were also helpful. He too never put a time limit on his contributions. Duncalf went into this project partly because he had long been a fan of Smokey's articles in Popular Science magazine.

Jim Duncalf

CTO and Patent holder

Jim is the guy who took on the challenge to lead the efforts to fulfill Professor Oppenheim's vision of an "Ideal Engine". His zeal for this project was inherited from father. In 1923 Jim's father electrified his parent's farm. The power came from a converted windmill connected to a bank of discarded railroad signal batteries. It was very popular in the area. Then in 1935, the police destroyed the system. A legal monopoly was given to the wealthy owner of a local power company. In many countries, large electric power companies are now seeking a similar legal monopoly to provide electric power to all the world's cars. In the last couple of decades some of the richest people in the world art trying to get a legal monopoly to sell electricity to the world's cars. But today a rising backlash is about to happen. Please resist!

Mark Beierle

Engine designer/builder

Mark Beierly, the head of design and major stockholder of Earthstar Aircraft Company, was our first licensee. Mark and his team built several generations of prototypes, the last one being a production version. Every one of the prototype engines gave clear proof that Professor Oppenheim's writing in several papers and books regarding combustion dynamics were valid. When Duncalf, Yunick, and Beierle turned Oppenheim's concepts into a working design the engine's thermal efficiency was very close to 50%. Beierle efforts, skill, and experience in engine design and his dedication to the building and testing of the engine were key in making the Rad Cam a practical and efficient power plant that will revolutionize the EV sector.
