Wow, no mention of Practical Engineering, yet?! https://www.youtube.com/@PracticalEngineeringChannel
This guy is doing a public service. He admittedly loves public infrastructure and civil engineering and does an amazing job of balancing the technical details and gist of the underlying physics and engineering constraints with the context of the real world applications.
Sometimes the topics are almost comically mundane, but I jumped into them and found it thoroughly interesting. One example is his 10-minute explainer "What is a Culvert"[1]. It's the perfect debunking of something seeming "trivial" to the casual observer. In another video he comments on why on construction sites you see so many folks "just standing around".
He has videos you can watch with your kids about things you might ordinarily just wave your hands about, like "How Water Towers Work"[2]. And then bigger more much involved explanations on topics you certainly have heard of but never bothered to look into, like "What Really Happened During the 2003 Blackout?"[3].
lol I feel like I sound like a advertisement but I really just love his work and thoroughly recommend having this channel in your repertoire. He's also just earnest, not unnecessarily dire or animated, and often gives what feel like fair and balanced perspectives on some of the social issues surrounding these topics.
