Human history has witnessed a great leap forward with the discovery of fire. Greek mythology attributes this major advance to Prometheus, when he brought to men this fundamental element, hitherto reserved for the gods of Olympus. Since then, its use has spread over the entire planet and today it is more about “controlling fire”, i.e. controlling energy in all its forms. That’s when the Smart City comes in.
