  • Having knowledge in power electronics i can confidently say the DC output of solar is easily and regularly inverted in phase with grid. In fact, DC is often used for undersea cables switching AC to dc then back to AC, All at extremely high voltage and varying demand(up yo 600kV/600MW but varying by installation).

    Wind turbines go online after the blades start spinning and connect to the grid in the same way as any other generator, controlled by internal electronics. Power is regulated through blade feathering and can be turned off as supply exceeds demand. This, other than for maintenance reasons, is why you might see one turbine spinning while the next is standing still. This capability actually means the grid is MORE stable with wind power.

    Any further fluctuation is managed in the same way as conventional power generation.




  • Yeah that’s fair. But the works and practice in mobilizing the workforce in the new deal played a big part in the US having industrial capability prior to WWII. Not mentioning other logistics, the power grid improvement alone may have made the difference in the war effort even being possible for the US. After the war private industry continued to benefit from cheap energy coming from those same projects. Hell if there’s a miuntain range in your state you’re almost certainly getting some of your power from a hydro plant made in the 30’s.









  • My 100% BS conjectures are:

    • to save energy versus committing the dream to long term memory

    • to facilitate childhood/adolescent development, as object permanence is learned you need the external world to be the consistent one. You can’t waste energy learning to adapt to the worlds in your dreams in later childhood.

    • as adults dream amnesia can help avoid relived or newly generated trauma incurred as the begin processes your external experience.

    Idk, there’s lots of possible benefits. In not about to do the research paper deep dive. But the wild part is that dreaming developed and the mechanism for not remembering the dreams also developed and there was a selective pressure for that to be the case.








  • Let’s start with infrastructure.

    Buses/metro/any public transit, barriered or not, sparsely or rarely exist. Even painted bike paths/walking paths, these usually exist ONLY in dense or older urban areas. You have either 1-1.5m wide sidewalk elevated 10cm or nothing separating you on foot from car traffic.

    So that 250m is often on the shoulder of car lanes.

    Now let’s talk property liability. You are responsible for injuries others sustain while on your property unless you have clearly posted signage expressing they were not allowed on your property. Even then and at best you’ll have to disrupt 6mo of your life tied up in courts+fees. (No right to roam. You do get the “perk” of open manhunting season on trespassers)

    So that shortcut through the neighborhood where your neighbor laid out gravel because they care about community? Nope, that’s cyclone fence or cinder block wall. That alley between flats? Gated off.

    It’s not even scale that’s the problem. You ALWAYS have to go around the ENTIRE block. A 250m Crow flight can easily be and most often is 1+km by foot, and only ever with a curb as your protection from traffic. You can’t safely get to geographically nearby places without putting yourself in mortal danger.

    Also note European road design limits traffic in residential areas where the US grid system means every road is a main road and wide enough to promote excessive speeding.
