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.
Rediscovering the Small Web
The vast open seas
We didn't have Google in the early days. Other search engines like Lycos, Excite and Northern Lights did exist but were nowhere near as efficient as modern search engines. Finding something you were interested in was not as simple as typing a few words and getting to that information in one click.
No, the web was much more of an adventure. It was a place that you wandered to discover new areas, like exploring the vast open seas. A new virtual space that lead to all kinds of strange, interesting, exciting places. This is what the web was like, at least, in our collective imagination.
The gatekeeper
Google has become the de facto gatekeeper of the web, an arbiter of what is useful and what should get visibility. Except, most websites that appear on the first page, the links that you are most likely to click on—less than 1% of searchers click on something in the second page—are designed to be there by optimising for Google's algorithms. One consequence of this is that most of the websites that people get to "organically" are created by professionals and marketers who "position" themselves on those keywords. This means that the smaller, amateur web gets hidden in the shadows of web professionals who design around specific keywords and audiences.
It can also be art
It is worth remembering a website does not have to be a product; it can also be art. The web is also a creative and cultural space that need not confine itself to the conventions defined by commercial product design and marketing.
