    Hmm, it probably depends what you think is weird, but I have one in their on the feasibility of extracting ammonia from biomass. There’s also one on early steam turbines by a fellow named Geoff Horseman, which is a fun name.

    Edit: Oh, I also have a professional critique of my dating profile photos. That’s weird in a different way, since I actually got that done, and it unexpectedly came as a PDF.

        It’s a beast too - 202 pages. From the part I read, I could probably make one that kinda works, but that’s it. Unfortunately the author didn’t go into the details I was hoping for, like why exactly steam turbine airfoils are hook-shaped. One neat thing is that they have a nice little formula for comparing totally different turbines over time to show how they gradually do more with less.

        The ammonia paper is weird because it’s a super impractical and difficult idea - normally you fix nitrogen in a big Haber-Bosch plant and turn it into biomass. Both came up because they’re applicable to primitive tech stuff.

        I have more and probably weirder, but the things I care about tend to be moved out of the download folder.

          I can definitely relate. I have several PDFs of advanced textbooks from when I wanted to learn some very niche skill. The latest one is an economics textbook from when I wanted to learn about different types of auctions and the maths/game theory behind each.
