     Finally, the heat loss factor that can be tackled is related to heating systems efficiency.
     For instance, one might want to replace older heating technologies for now ones. For instance, gas boilers can be replaced by condensing gas boilers: 
     water vapour, produced by the combustion reaction is condensed to retrieve the consequent amount of thermal energy that is released during this process, instead of just losing
     the potential heat by releasing the steam in the outside environment.

+Throughout the nineteenth century, identification means evolved towards documents with physical description of the individual (at the time, photography was not widespread), seals, signatures,\dots.

+Then, at the beginning of the twentieth century, passports started to include photographs and all sorts of information: height, date of birth, place of birth, address\dots

+    When traveling around the world, airports are a major frontier place. As most long-distance travel are made with planes, most people go through airports 
+    when going in a foreign country. This makes airports a very sensitive place, as they are the gateway to a country. They must filter between desired traffic (tourists, workers,\dots) and undesired traffic (criminal, terrorists, illegal merchandise\dots).
+    Therefore, security is a huge matter when it comes airports. They are the most surveilled and secured places one can experience in the modern world.
+    The size of such a challenge is proportional to the tremendous flow of daily passengers.

+    Finally, airports are the perfect place to describe the concept of hybrids.
+    Hybridisation is the phenomenon happening the a human being becomes inseparable from a material object.
+
+    In the case of an airport, the human being and its passport, especially in the context of the airport are deeply interwoven.
+     Obviously, the passport has no mean being in an airport without the corresponding human being. But the symmetric situation is also true, the individual has no use
+     being in an airport without its passport. This little reasoning shows that the individual and the passport are inseparable from each other.
