Here you have the video of the program “ Spain flush with sky”:

Francis: “The sun is about to set and the night takes hold immediately of the city. In your homes, you give it to a switch and then light up the kitchen, the living room ... but How a big city lights?, Is there a person in charge of activating a device?. We are going to see that: of how it illuminates a city. Illuminate a big city like Madrid is very complex, so there are experts who devote half a lifetime to study it.If I want to know how to light the cities, there is only one person who can tell me. Which part is the first to be turned into a city, such as Madrid?”
Alejandro Sánchez (University Professor): “The first thing that usually illuminate are private facilities, that have a lighting system a bit archaic, but that more or less works and is a clock, which at a certain time, you set it and goes on”.
Francis: “And tstreets or the more important city centers How to go?”
Alejandro: “The most common is to have a special sensors to detect how much light there is, well, hey, will darken and then sends the signal to begin to illuminate. And another, is a type of watch, special, called "astronomical clock" which calculates what is the ideal time to start to light streets.Then, you see how lights only what you want and when you want”
Francis: “What are we seeing now?”
Alejandro: “Now we are seeing how the suburbs are very bright, the M-30, however there are other areas of Madrid, which still is not lit, because they have the astronomical clock, which still has not sent the signal lights”.
Francis: “And goes through phases…”
Alejandro: “Sure. Then, depending on what kind of watch they have, are illuminated some zones or other first”.
Francis: “I called attention to the bottom is on and yet is off around”
Alejandro: “We have the same street, with different phases”.
Francis: “What happens?”
Alejandro: “It is due to these different watches, which I mentioned. For example, we could imagine that this first part is with a clock, an hour, plop, at that time is on”
Francis: “Can we see now how this going on?”
Alejandro: “Yes, also looks like a different color ....it is because.thay are heating lamps and take a while”
Francis: “And there is a common point in the lit monuments in Madrid, for example "
Alejandro: “Yes, More or less at around 10 pm is programadio, to illuminate the monuments: La Almudena, Royal Palace. La Torre Picasso”.
Francis: “What is the trend in the world with this about light?
Alejandro: “That the lighting fits what is really happening on the street: no people, then the lighting is minimal and where there are people, which is maximum, that is a smart lighting "
Francis: “Well, I was very clear that there is nobody who press a giant switch to light up a city and that cities do not light all at once, Spain does not light up all at once, but it goes in phases , now we can say that Madrid is 10 pm and that everything is illuminated”….” We have seen how, thanks to technology, our homes, streets and cities remain lit when the sun sets in the West. Spend more or less light, the Spanish are nocturnal by nature: when we go out, at whichever hour, we always find people on the street. A recent study from Nielsen, conducted among 15,000 Internet users, confirms that the Spanish are the ones who later fell asleep in Europe”.
I hope that you want to come to Spain in order to confirm it.
Till soon, kind regards,
Luis.
