Some simple facts about the so called “Thompson Coupling”

1) the “Thompson Coupling” is essentially an assembly of two universal joints with a linkage that ensures that the angles between the universal joints and the input shaft and output shaft, respectively, are the same

2) the knowledge that this arrangement offers a constant velocity performance is at least 100 years old and is nothing new or novel, a vast variety of linkages have since been developed or patented with exactly the same objective in mind, none of them has ever been considered as a commercially viable product in any industry

3) in order to be competitive with existing technologies in a mass production environment such as the automotive industry, a new product will be assessed in accordance with two selection criteria, “Power Density” and “Cost”; the “Thompson Coupling” or any other “two universal joint linkage assembly” inherently cannot compete in these two selection criteria, by a large margin

4) whilst “inventions” like the “Thompson Coupling” provide good entertainment material for the ABC, it is inexcusable that so called “Professional Institutions” like “Engineers Australia” and others, do not, or more likely, are not capable of researching the background and technical potential of a new technology, and consequently are culpable of misleading the public; the “Thompson Coupling” ranks in the same category as the “Sarich Engine”, neither of them were either novel, at the time of their patent lodgment, or have the potential to ever succeed as a mass product; “Engineers Australia” has promoted both of them

5) there is a fine line between “ignorant inventor enthusiasm” and plain fraud

anyone still interested in investing in the “Thompson Coupling” here is an opportunity
