"A concerned technician" is the alias used by a blogger and tuitero who since 2011 has been on the internet with that alias. I am a technician specialized in electrical lines and machines, I train in the old FP, the 5-year-old. . . when an Industrial Master was that, a master. I've been at the foot of the canyon for about 30 years, working for almost every power company in this country. The last 20 in a foreign multinational as Senior Service Engineer.
