The Alyeska oil pipeline, which runs from Prudhoe Bay to Valdez. This is on S.R. 4, south of Delta Junction. It's on a fault line, so this stretch is built to withstand a substantial earthquake -- the pipe can move several feet in any direction without breaking.
This pipeline was once used to carry freshwater from Buntzen Lake to the Burrard Thermal Generating Plant. A new larger underground pipe is now used.
In November 2013 the provincial government announced that BC Hydro will stop generating electricity at Burrard Generating Station by 2016.

Pipeline Road is considered by many to be one of the best birding locations in all of Central America if not the world. It's possible to see 300 species in a single day, and a world record of 450 species in 24 hrs. was set there in 1985...The 17 km. road provides access to both forest and wetland birds. Numerous side trails plus 11 creeks and rivers can be followed into the forest. Army ant swarms often attended by antbirds and sometimes Rufous-vented Ground-cuckoo are found frequently.

In sections where the pipeline is elevated, a zig-zag design is apparent. This configuration contributes to the flexibility of the line, converting the changes in the line length to sideways movement. Between anchors or the four supporting legs, the pipeline can move sideways on its cross beams a total of 12 feet in case of thermal expansion and contraction, and another 2 feet in case of seismic activity.
092013: Nogales, AZ - This Inukton Pipeline Robot is used to travel down pipes and tunnels that may be too small for a person to crawl through. The Inukton has a camera mounted to the front of it and the Border Patrol Agents can control the robot and view what its seeing from a control box. The Inukton Pipeline Robot was purchased Asset Forfeiture Funds, so it did not cost the taxpayers any money.

The Trans-Alaska Pipeline System, usually called the Alyeska Pipeline in Alaska or the Alaska Pipeline elsewhere, is a major U.S. oil pipeline connecting oil fields in Alaska's North Slope to a North Pacific seaport where the oil can be shipped to the Lower 48 states for refining.
The main Trans-Alaska Pipeline runs north to south, almost 800 miles (1,300 km), from the Arctic Ocean at Prudhoe Bay, Alaska to the Gulf of Alaska at Valdez, Alaska, passing near several Alaskan villages and towns, including Wiseman (pop. 21), Bettles (pop.39), Livengood (pop.29), Fox (pop.300), Fairbanks (pop. 34,540), and Glennallen (pop.554)
Oil emerges from the ground at up to 180 °F (80 °C), and travels through the pipeline at temperatures above 120 °F (50 °C). In some elevated portions, heat conduction from the oil through the Vertical Support Members (VSMs) would melt the permafrost in which the VSMs are embedded. This would cause the pipeline to sink and possibly sustain damage. To prevent this, these portions of the pipeline include heat exchangers atop each VSM, passively cooled by convection to the air. Each heat exchanger is thermally coupled by a heat pipe to the base of the VSM. Running through the VSM, the heat pipe transports heat from the base to the heat exchanger. Since ammonia, the working fluid in the heat pipes, has a freezing point lower than the permafrost, the heat pipe works throughout the year, even during the coldest winter nights. This convection cooling system is thought by TAPS engineers to be the greatest innovation associated with the pipeline.
Another innovation associated with the pipline is the zig-zag configuration aboveground. Since pipe shifts around far more easily aboveground than when buried, the zig-zag path of the pipeline allows the pipe to move from side to side and lengthwise. This movement may be caused by earthquakes or by thermal expansion and contraction. The VSMs also include "shoes" to allow for horizontal or lateral movement, and crushable blocks to absorb shocks from earthquakes, avalanches, or vehicles.
A major challenge of the Human Genome Project was "annotation", or making descriptive sense, of the raw DNA sequence. Output from an automated capillary sequencer, with each of the four DNA bases labeled a different colour, forms the raw data. These data are then processed with various annotation "pipelines", including assembly of the raw reads into larger "contigs" and ultimately a finished genome sequence.
Represented here is the transition from primary sequence data (left) through the "brain filtering" and computer processing of bioinformatics (right). The image has been treated with a simulation of the "bleach bypass" developing technique used on photographic film in the pre-digital, genome project era.
[The preceding pompous description goes with this piece of "art", submitted for consideration as part of a gallery exhibit for an institutional fundraiser. I can call it pompous with impunity, because I wrote it.]
