Hello Mary Yugo, I've looked at all of your posts for months, and appreciate your candor, spunk, restraint, keenness, patience and persistence -- it seems that the desire for a major game changing breakthrough since 1989 leads to premature big gambles that so far always fail -- so the whole enterprise develops a traumatic history with many cycles of flash and fizzle for each new device -- so there isn't support for gradual basic research that establishes tiny beachheads, one after another -- the research that led to the game changing discovery of uranium fission in early 1939 was fairly routine, straightforward simple nuclear chemistry, and it took months before the correct paradigm was found -- likewise the evolution of transistor technology after 1948 depended on advances in growing extremely pure crystals of germanium and silicon via "zone refining", and finding and eliminating nano level impurities that poisoned the electronic properties of n and p conducting regions -- very painstaking, detailed baroque recipe work that usually was trial and error -- however, the evolving frontier of science and technology is a forever evolving and expanding complex fractal horizon -- so if CF is possible, someday it will unpredictably show up in some arcane corner in the fractal -- perhaps in "water tree" corrosion in dense polyethylene insulation in high voltage power cables?
Merry Christmas and a vigorous New Year! Rich
