Mark Beierle: Validating Rad Cam As president of Earthstar Aircraft, Mark Beierle signed the first Rad Cam license and led prototype development. Together, Duncalf, Yunick, and Beierle had transformed Oppenheim’s concepts into a functioning engine. 

His final production‑ready design proved Oppenheim’s combustion theories correct, achieving near‑50% thermal efficiency. Beierle’s expertise and relentless testing transformed Rad Cam into a practical, efficient power source with the potential to revolutionize EVs.olve.
