Thanks for the article. I found your articles professional quality and for free. :-) My father worked for a chemical company(10000 workers in Asturias, Spain) as chemist . He realize that he could buy a conventional ceramic oven for doing the same that another specific one that costed 100 times more. He tried to convince management. They denied the permission. He tried again with different ideas, it never worked. PD: Well, it worked better in another (later) smaller(100) company. The trick if he had a good idea, was to say it was an american method (Seems they didn't trust in local intelligence, this was in Madrid, Spain)
