I am only hypothesizing because I know what I don't know. As for your question, could it be that Mr. Bordynuik and his previous team were good at developing and building the process from a technical point of view but were not as proficient on the commercialization of the technology?? In steps Mr. Heddle and voila, he finds a situation where the process will add value and announces the sale of 6 processors. I think that if Econavigation doesn't see an economically beneficial output from the process they would not be interested in it nor would they be spending money to quantify that benefit.
Now you may ask, "Why hasn't the stock skyrocketed?" Well, I think that Heddle is not as forthcoming with claims and rhetoric as Bordynuik was in the past and is moving more cautiously and meticulously so as to avoid the backlash from the market and investors that eventually led to Bordynuik's resignation. Heddle is an accomplished and successful businessman. He doesn't necessarily communicate as efficiently as we would like but, I think that stems from him coming from the private sector and adapting to the public sector.
