I seem to recall an IEEE Spectrum article about power infrastructure in Iraq. Several years ago, literally billions into building and rebuilding power stations and substations. After just a couple of years, they were nearly all derelict or inoperable. The reason was that while lots of great equipment was installed by GE and other well known names in the electric power business, the Iraqis who were brought in to run the new stations were given no training on maintenance. (I'd hate to be the guy who overlooked that small detail). Regards, -Roberto -- Roberto C. Sanchez http://people.connexer.com/~roberto http://www.connexer.com
