A Journey Fueled by Passion
From a young age, Knob was drawn to the intricacies of mechanics, particularly motorcycles and combustion engines. After a short stint in motocross racing, he pursued his passion academically in Prague, specializing in aviation technology and combustion engines. Despite facing health challenges during his studies, Knob’s determination saw him transition into a successful entrepreneur, focusing on the creation of innovative technologies.
Knob’s breakthrough came when he began manufacturing gearboxes and sequential shifting mechanisms for race cars, reinvesting profits into further research and development. This dedication to innovation earned him the prestigious Český Goodwill award in the Innovation category in 2024.
The Game-Changing Range Extender
One of Knob’s most notable inventions is the range extender – a motor generator designed to recharge the batteries of electric aircraft or hybrid cars. This innovation addresses the limitations posed by heavy batteries, allowing electric planes to extend their range without compromising on safety and performance. Knob’s patented motor generator eliminates vibrational forces, making it ideal for aircraft equipped with sensitive instruments.

This technology has garnered attention globally, with Knob securing patents in the USA, China, Korea, and several European countries. His motor generator promises not only to revolutionize aviation but also to find applications in hybrid electric vehicles, offering a compact solution that can be integrated even under vehicle floors.
Future Endeavors and the Birotary Engine
Knob’s ambitions don’t stop at the range extender. He has also developed a Birotary engine – a three-cylinder, four-stroke piston engine arranged in a star configuration. This engine design combines the advantages of traditional piston engines and rotary engines, achieving high efficiency with reduced vibrations.

Currently, Knob’s Birotary engine is in its advanced prototype stage, integrated into ultralight aircraft. While further development is temporarily on hold due to financial constraints, Knob remains optimistic, seeking strategic partnerships to bring this promising technology to market.
A Critical Eye on Green Policies
Knob also voices critical views on current global warming theories and green policies like the Green Deal. He argues that these policies often overlook the fundamental science behind combustion engines and their efficiency. Despite his skepticism towards mainstream environmental strategies, Knob remains committed to sustainable innovation, particularly through his work on range extender.
Conclusion
Václav Knob’s story is one of resilience, innovation, and unwavering commitment to advancing automotive technology. His work exemplifies the spirit of Czech engineering prowess and offers a glimpse into a future where his inventions could play a pivotal role in sustainable transportation solutions.
As Knob continues to explore the boundaries of what is possible in engine technology, one thing is clear: his contributions will leave a lasting legacy in the automotive industry.
