El siglo de la luz, Historia de la electricidad en México (2000)

From turning on a lamp to making complex machinery work is now a simple and everyday action. Millions of people would not be able to imagine their daily activities without the presence of electric energy. If prehistoric man was able to produce fire and through this possess the first source of light, 5,000 years would have to pass so that this mysterious force generated by nature could be controlled by man and transformed into electricity.
