Tracing Power Lines with the Pylon Appreciation Society
Pylons
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.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
Ruins, Rub-outs, and Trash
Tracing paper into palimpsest
Kahn's preferred medium was charcoal. He liked to use the side of his hand to rub out the thing he was drawing in order to draw it over, and over again.
Turning the tracing paper into a palimpsest; where some trace of each previous marking is still there, only blurred out and faded back by Kahn's rubbings-out and re-renderings, so that in what he made there is also the record of how it was made.
Charcoal on trash collected over time acting as ersatz animated film recording how Kahn's ideas developed.
So insufficiently palimpsestic
I worry that unlike Kahn's process and tools, the processes and tools we use are aimed at helping us satisfy the demand for moving fast and breaking things, not to be good, or to better ensure the doing of good work.
My son Gerrit told me about a YouTube video from a conference where the presenter asked for a show of hands from video game developers in the audience who could produce or successfully compile their own code from the previous quarter. Or from the previous year. Or from two years ago. And by that time the point had been made: nobody had their hand in the air.
Good for the next man
Lou Kahn said that a house is only good if it's good for "the next man."
He knew that the likelihood of its spaces and places continuing to be loved after "the first man" has come and gone requires the kinds of attention to detail you'd have to be paying if the next man and the next-next man were embraced as stakeholders from the onset.
