"Nanotechnology as an idea doesn't have any problems per se, particularly as nanotechnology that does have problems doesn't exist. However, there are problems with some of the public depictions or expectations of nanotechnology, especially if portrayed as "just around the corner" instead of part of the abstract sci-fi realm along with things like anti-gravity."
"The main practical problem with nanotechnology is the phrase being overused as funding hype for what anyone else would call material science or synthetic biology."
Also, we learned that the so called "cost effective solution" is illusory for the most part. Nano DOES NOT WORK in mass production. The equipment required to apply the nano material DOES NOT EXIST.
Scott Moore is likely a fuel cell addict that knows that the fuel cell dream dies off with every $10 gain in the price of Platinum.
We had a high placed auto m. engineer just comment that the nano tech. does not understand mass production reliability requirement. He said it is fog shot to claim that equipment is in place to be able to reliably produce the high quality cats that the nano people are claiming.
Basically, Mazda stuffed a very EXSPENSIVE nano cat into one of their production vehicles that developed a "fiber film" over time. What he is saying is that the parade was short lived, contrary to the mantra of "right around the corner."
The primary issue for nanoparticles is they are less stable at high temperature, thus wash coat depletion is accelerated. This phenomenon opposes increasing operating temperature requirements, such as locating element ever closer to the heat source.
