  • In fifty years when a 30kW solar power system is working like a 20kW system the geopolitical system will probably be different

    Buy or from whoever is making it. America, Australia, and China are certainly making panels, most likely other countries

    Other electrical equipment is made everywhere

    The “what if you need more” argument is also a thing for gas hot water, internal combustion engines and everything else

    Electric is no different, except it doesn’t need fuel




  • Again, making assumptions about what every light will be like. Different places installed different things at different times.

    Again?

    It’s a fair assumption, for the last 70 years electric capacitance sensors (metal detectors) have been a tiny fraction of the cost and complexity of weight sensors. I have never seen a weight sensor at traffic lights in any of the three countries I have driven in. Roads don’t last 70 years, weight sensors on roads are lucky to last 20 years

    https://en.wikipedia.org/wiki/Traffic_light doesn’t see fit to mention any sensors other than inductive loop (metal detectors) and the long list of related things on that page don’t include alternative sensors, though video sensors do also exist

    No way does Germany use anything other than inductive loop detectors, unless they have Netherlands style AI camera systems to change lights before the vehicle arrives

    And a search on what technologies Germany uses resulted:

    • Induction loops
    • Cameras

    Weight is not included, no surprise to me as it’s so expensive to maintain

    My point is you don’t need people with doctorate level education to run a solar plant, you occasionally need people with a technical level education to fix stuff, or near unskilled to clean

    And if you need parts they don’t come with the x hundred percent markup for certification that nuclear has
