I don't think the Kremlin can win by attrition like they have in the past. They're burning through USSR stockpiles and not replacing them, they're in the middle of a demographic crunch even without the war, and the last mobilization was deeply unpopular.
This isn't the USSR, it's just a corrupt, isolated, shrinking Russia being dragged into a barbaric war by their Mafia leaders in the Kremlin.
Trains can run on renewable energy. For now almost all container ships use bunker fuel, which is absolutely terrible. Would be great to see them switch to renewables energy like sails and solar panels.
