THE INVENTION

The apex of a triangle in contact with a racetrack traces out a recognizable four-leaf clover as it rotates. The shape of the racetrack in its mathematical form has been US patented, No 6,718,938 B2.

The racetrack forms the engine casing inside which the engine segments rotate. 

DEVELOPMENT

The concept for the engine was conceived over 15 years ago. After much work, effort and development, it was brought to reailty in 2008 by its inventor, Peter Szorenyi.

The Engine was awarded an ACT Research and Development Grant of $63,000 in

2001. Since that time, three prototypes of the engine have been produced and the design refined. A “proof-of-concept” engine run was achieved on February 26, 2008. The current prototype is assembled and ready for further testing. 

Suitable parties are sought for the future development of the engine.  Those interested are encouraged to contact REDA through the Contact section.
