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.
Every Tool Shapes the Task
Imagine the world like a cake
Imagine the world like a cake. Imagine that you slice it into the customary slices by vertical cuts. Each slice of that cake should signify for us, a constituency. Each is geographically located as one segment of the larger cake. Each slice is more influenced by its immediate neighbors than by what might be in the cake quite far away.
What technology has done in the world increasingly is to put horizontal cuts in that cake. You don't only talk up and down. Now you can talk across barriers.
Power makes knowledge sufficient
Whether it is civil rights' violations in many countries, whether it is the increasing numbers of unemployed people in our own country, whether it is the homeless we see on our way to work, it isn't as though we don't know.
But there is that horrible realization that, while the knowledge of facts may be a necessary condition for action, and we talk about democracy in civic action, it is unfortunately not a sufficient one.
While knowledge may be a necessary condition, it may in fact be a less necessary condition that the one that makes that a sufficient condition, and that is access to power.
To do some more pushups on the internet
There may be a lot of things that have to be studied, but there is also what I call "occupational therapy for the opposition" that says, send them off to do some more pushups on the internet. You need to be mindful that it is possible to use information, and the need for information, as a delay for the call for action.
Adding up to hair-brained
I have for myself come to the point where I say that people or groups or governments make the decisions that make sense to them, even if they look totally hair-brained to me.
My task then is to figure out the constellation of forces, the pushes and pulls, that in fact do add up to that hair-brained decision-making. Then we can go into the next iteration and say, "What can we do about the balance of the push and the pull that seems to result in totally non-constructive decisions?"
Who the problems are
Recently my attention was drawn to a quote from Peter Drucker who said, "If there isn't dissent, we would not know where the problems are."
I said to my husband, "Look, if there isn't dissent, we wouldn't know who the problems are." I think one has to keep that in mind.
Your new electronic microscope
Learn what is in this Internet. But then keep your head clear and go back to your goals. What in fact, in the best of all worlds, do you want to do? Do any of the activities with your new electronic microscope bring you closer to that?
Cyberspace as a global dump
If we think that cyberspace is a public space, then let's think of the oceans. They used to be as much of a world resource as anybody could think of but didn't belong to anybody. So everybody put their garbage into them. The potential of cyberspace as a global dump is quite substantial.
