Patterson probably failed because he never had anything that worked and was deluding himself and others.
Dennis Cravens tested them carefully, independently of Patterson. I looked closely at his work, and I visited the experiment. As far as he & I could tell, they worked. Perhaps we were deluded but I don't think so. I do not think you can point to any technical reasons showing how and why we were deluded. If you cannot say "you were wrong for reasons A, B, C" where A, B and C are specific technical reasons, then you are merely saying it is your gut feeling we are wrong. Your gut feeling cannot be tested, proved or disproved.
(A "gut feeling" means intuition. Intuition is often right. It is powerful, instinct-based feeling that should never be ignored. But it cannot be debated. It is never proof of anything.)
