Learning to live with low technologies
Let's analyze for a moment the current life, the one that connects us to our mobile phones, real computers.
According to a 2009 study, they consist of: hydrogen, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, potassium, titanium, chromium, manganese, iron , cobalt, nickel, copper, zinc, gallium, arsenic, bromine, strontium, yttrium, zirconium, molybdenum, ruthenium, palladium, silver, indium, tin, antimony, barium, tantalum, tungsten, platinum, gold, lead, and bismuth. Just that !
The supply circuit is very complex. When one thinks of the circuit of a simple supermarket egg ... one can imagine what is involved in the supply of raw materials for a mobile phone (search for deposits, extraction of the subsoil, transport, transformation ...): plastics from Saudi Arabian oil, Chilean copper, Democratic Republic of Congo cobalt, Bolivian lithium, Russian nickel, Chinese zinc, etc.
Who can say that he masters such a sector?
Who knows how to estimate the geopolitical consequences that they entail (wars, maintenance of dictatorships, exploitation of the populations ...).
This reality directs us towards a society essentially based on low technologies, undoubtedly harsher and basic, perhaps a little less powerful, but much more resource-efficient and locally controllable.
How to integrate it into our project? no tractor, no sophisticated machine for pumping water, heating that uses only the thermodynamic circulation until the use of dry toilets, the materials used will be essentially wood, worked with hand tools, the straw and earth, bamboo, etc.
We will have to build ourselves a wind turbine to raise the water, build a heating of buildings that uses thermodynamics (as the Romans knew so well do it), to make the thermal insulation with straw, etc ...
Of course, we will still take advantage of the technologies of our civilization to start projects. So the permaculture mounds will be dug with a digger, the fence will be made of steel mesh and the shed will be delivered ready to be mounted because these are the elements that allow us, little by little to bring together the actors of our evolution.
We will thus learn a lot from each other, by experimentation with trial and error, and we will have to deploy a lot of intelligence to succeed simple things.
