💡 From Persistence to Breakthrough
“I have not failed. I've just found 1,000 ways that won't work.” —Thomas Edison
Every transformative technology passes through three phases: concept, development, and commercialization. For the 4-stroke automotive engine, this journey spanned 37 years—from 1861 to 1898—until the Benz Motorwagen became the first mass-produced car.
The development of Kamtech’s On Board Energy (OBE) system followed a similarly demanding path. Fueled by dedication, not full-time effort, our mission was clear: to conserve energy and build a cleaner, more peaceful world.
Like the scholars whose innovations often remain buried in technical papers, our team faced countless setbacks. With perseverance, we often went to the authors themselves, who had hands-on experience in solving problems.  The development was inspired and instigated by Professor Antoni K. Oppenheim, who outlined the original vision in a 1982 SAE paper.  Early support was given by famous mechanic Smokey Yunic.  Mark Beierle, of our first licensee, Earthstar Aircraft, helped perfect the platform, producing prototypes # 3-5. The production version in flight is seen above.  Then, more recently, Professor Huynh Thanh Cong advised us on the final phase of the development.  But history proves one truth: success is born from relentless iteration.  
🚀 Ready for the Next Licensee
After years of redesigns, rebuilds, and rigorous testing, we’ve created a production-ready design of the Rad Cam engine, a compact, efficient power source that outperforms conventional 4-stroke engines in ease of manufacture, robustness, thermal efficiency, compactness, and cost.  A modular design that has been:
  • Proven in light aircraft
  • Adapted for electric vehicles
  • Refined through six prototype platforms and improved with hundreds of modifications.
Kamtech OBE is ready to reshape mobility. We’re seeking visionary partners to bring this breakthrough to market.
