    Lors de la dernière législative j’ai voté par internet (français de l’étranger).

    L’élection de notre député et un nouveau vote a été effectué car une partie des électeurs n’ont pas reçu les SMS avec les codes de vérification pour voter.

    C’est ça le problème du vote par internet, ça fait reposer le bon déroulé des élections sur des acteurs privés.

    Ça ouvre la porte a tellement de manipulations potentiels. Dans le cas des français a l’étranger aller voter leur signifier devoir prendre un billet d’avion a plusieurs centaines d’euros, une nuit d’hôtel et deux jours de voyage. Dans ce cas la balance penche en faveur du vote par internet malgré les défauts, en métropole c’est moins évident.

    Oil is honestly an amazing product, chemistry wise there is so much we can do with it and energy wise it’s a extremely concentrated and easily transported form of energy.

    Energy wise one liter of oil is equivalent to 10 person working for a day !

    I repeat, using one liter of oil is like having 10 “slaves” working for us for a day.

    Its easy to see why oil became the base of our modern civilization, and easy to see why we don’t manage to stop using it even though it’s destroying us.

  • I stopped reading the article there.

    Either the author is voluntarily misleading or he has no idea of what he is talking about.

    Here is the map all the fast charging stations (>100kW) along the way between Paris and the Mont St Michel.

    The Tesla model 3 in Europe uses the standard combo CCS plug so it can use all of these stations.

    I did not count them but at a first glance the number of charger is higher than “none”

    Edit: OK I read the article after all but I really don’t see what problem battery swapping would solve.

    I could see a use case for public transport that has to go a specific road and need to run non stop every days but even then I suspect that having overhead cable on a short section to charge the battery while running would be more appropriate than battery swapping.

    The article is talking about the lack of charging station but battery swapping just make the problem way way worse. A battery charger is just a parking spot and a high voltage AC - DC transformer connected to the grid. It’s relatively cheap and easy to install, does not take much space and work for all electric cars compared to a battery swapping station that can only work for one specific brand (specific model too ?) need robotics and plenty of storage. Its much harder and expensive to install and you need one charging station per brand. This means less stations overall.

    Finally there is the speed of charging, this is true that battery swapping is probably faster than fast charging but honestly I don’t find charging an electric car that inconvenient.

    On long highway trips I need to stop around 20 minutes every 2 hours, a 20 minutes break every 2 hours is not that bad, just enough time for a toilet break, a quick coffee before going back on the road.

    Energy is only a fraction of the issue and easily solvable, I’m not a 100% certain but I think that some mines are even powered with renewables energy.

    The main issue is tailings, millions of cubic meters of toxic, sometime radioactive, full of heavy metals mud. The tailings are piled up behind dams that regularly breaks and contaminate entire regions.

    Even of the dams don’t break it is still hundred of square kilometers of land that is contaminated for millennia.
