    Wood tower@4. I am slightly obsessed with tall wooden structures. This one will be ~30 meters, and occupied buildings now 'top out' at about 50 meters. A 75 meter church. A 118 meter radio tower. Little notice seems to be paid of 180-meter ATLAS-1 Trestle:

    ATLAS-I - Wikipedia

    Constructed (because it had to be) completely without metal.

    All are notable design/construction achievements. But this obsession is fueled because (a few kinds of) trees grow to 120 meter self-supporting structures. Just rings of cells replacing themselves with a new set, higher and wider. No cross-bracing or glue lam or any other 'engineering'.

    The wood of tree, presumably, could grow itself higher in this way. It is liquid water cavitation that limits uppityness.
