  • For 3D printers I think prusa is the bramd that can be trusted with quality.

    They are expensive but made in Europe and very reliable out of the box. I’ve been printing tons of parts for the renovation of my house and tools organization with no issues. I just start the print and come back once it done. Now I even do it remotely from work.

    Compared to my brother who had a Ender 3, tinkered quite a lot with it but was constantly baby sitting the prints and eventually just gave up on it.




  • I lived for two years in Cameroon when I was a kid (around 4-5 years old), we were regularly spending time with another family who had kids and the same age.

    Fast forward 15 years later, I’m 19 entering university in a totally new city in France. The first day every student is sitting in the amphitheater and they call the name of every student.

    When they call the last name of the person close to me I recognize the name so I use it as an ice breaker to start a conversation saying that I knew a family with his name in Cameroon when I was a kid … He says that yeah he lived in Cameroon as a kid at the same time as I did, so here we go we found each other again 15 years later !


  • I think I’m on an accepting phase too.

    I’ve been through a lot personally and emotionally since I started reading about collapse 9 years ago.

    I had a look at this publication a few years ago, it put me in a rough place for a few days.

    Recalibration of limits to growth: An update of the World3 model

    Humanity will survive I’m certain of it, however our thermo industrial civilization will not and most of the people currently living in the planet will not.

    It will happen whatever I personally do.

    The best I can do now is to find ways to have the happiest life I can using as little ressources as possible for my family, my community (neighbors, friends …) and me. It’s a process that forces us to reassess a lot of things we were doing but it is fascinating.

    Practically it means finding ways to lower our monthly expenses, try to consume local as much as possible and learning a lot of new techniques…




  • Yes, the map sources try to include the CO2 emissions of all the chain.

    When doing that you see that nuclear still has very low emissions. Nuclear is a lot of CO2 emissions for construction but after that there is not much. The fact that most of the French nuclear reactor are almost 40 years old means that the impact of construction is already diluted.

    Uranium mining is polluting, yes, but you need so little that it does not really have a big impact on the CO2/kWh ratio. 1kg of natural uranium produce as much energy as 14,000kg of coal !

    What is interesting on this map is that right now the green countries either have a lot of nuclear, a lot of hydroelectricity or both. Country with a lot of wind and solar struggle to meaningfully lower their CO2 emissions. I think it will come but right now the backup power used for when solar and wind production are low is often polluting and counterbalance the low emissions of renewable energy.




  • You forgot water in your scenario.

    To be fair most people in a first world country don’t need to think about water since it’s just “there”, all the time.

    But as soon as the electricity goes out the water supply goes out too.

    No water supply means no water to drink, with no water the human body die within 3 days, so people will start to rely on any dirty water they can find.

    About dirty water, no water also means no WC. I repeat: no WC so no evacuation of feces and urine. Within a few day a big city swill be covered with human excrement. Mixed with no clean water access it means that deadly waterborne diseases will spread extremely quickly.
