Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
I recognize this is a very niche endeavor, but the art and craft of maintaining a homepage, with some of your writing and a page that's about you and whatever else over time, of course always includes addition and deletion, just like a garden — you're snipping the dead blooms. I do this a lot. I'll see something really old on my site, and I go, “you know what, I don't like this anymore,” and I will delete it.
But that's care. Both adding things and deleting things. Basically the sense of looking at something and saying, “is this good? Is this right? Can I make it better? What does this need right now?” Those are all expressions of care. And I think both the relentless abandonment of stuff that doesn't have a billion users by tech companies, and the relentless accretion of garbage on the blockchain, I think they're both kind of the antithesis, honestly, of care.
