If you read news sites like Physorg.com there are many stories of breakthrough technologies. It seems however, that these breakthrough technologies just don't appear on the market or take several years to do so. Why do these technologies take so long to appear? Why do these technologies sometimes not appear? Do these news sites hype the story to present an unrealistic picture of the technology or is there some obstacle that prevents these technologies from appearing on the market? What could be done to increase the speed at which these technologies enter the market?
