Can UPS save millions of dollars on truck fuel simply by cutting down on its drivers' left turns?
Apparently, the company has been trying "to re-engineer their fleet routing," the Financial Times reported last month, as a way to find more fuel-efficient modes of delivery – and part of this means they're now limiting left-hand (or cross-traffic) turns.

As the Financial Times explained:

[I]nformation technology has an important role to play in making existing vehicles more efficient, particularly when it comes to aggregating small gains across large fleets. Take something as simple as reducing left-hand turns. For US drivers, this means less time idling in the middle of the road waiting for oncoming traffic to pass.

UPS route engineers are thus relying on "an underlying map database that can penalise or disable left-hand turns in the route planning process. The system is well suited to the delivery business because drivers can run circular routes, ending up where they started."
The FT goes on to explore the fuel-use implications of just-in-time delivery; air & truck delivery vs. water & rail transport; a "computer model that would create commercial freight routes in the way that MapQuest or Google Maps make maps for motorists"; and something called Gift: the Geographic Intermodal Freight Transport model.

Elsewhere, sudden transformations of the earth's surface, as a result of mudslides, floods, volcanic eruptions, and other topographical catastrophes, can make existing maps obsolete within seconds.
This is precisely what happened several weeks ago when an earthquake struck on the floor of the south Pacific, off the coast of the Solomon Islands, near Australia, raising coral reefs several meters out of the water – thus killing the reefs and creating a new, sun-bleached archipelago.
"Submerged reefs that once attracted scuba divers from around the globe lie exposed and dying after the quake raised the mountainous landmass, which is 32-kilometres (20-miles) long and 8-kilometres (5-miles) wide," Seed magazine reported.
The sudden terrestrial shake-up also "revealed a sunken vessel that locals believe is a Japanese patrol boat, a remnant of the fierce fighting between Allied forces and the Japanese in WWII."
Pulp sci-fi novelists may want to bear this in mind when coming up with future storylines.
For instance: an earthquake off the coast of Chennai thrusts a submerged geological ridge into the sunlight – revealing an unexplained metallic anomaly within those slabs of shell-encrusted limestone. Scientists called in to investigate are almost immediately hospitalized after visiting the site, suffering from headaches and nosebleeds. Local fishermen report identical symptoms.
Instruments, however, record a complete absence of radiation – so there must be something else going on.
Intriguingly, the exposed metal structure appears to be growing....
Etc. etc. Like I say: pulp science fiction.
Moving on, we learn that geothermal energy is on the rise in southern Germany.

According to Monocle, "Munich and its hinterland have become the new frontier for deep-seated geothermal energy":

Drilling three to four kilometres into the earth's crust allows engineers to tap into boiling hot water, which can be used to heat buildings and run zero-emission power plants. The southernmost past of the state of Bavaria, along the Alps' foothills, is the literal hotbed of geothermal exploration, with planned investments of €3.2bn.

Siemens, unsurprisingly, is fast on the draw, with a new plant already under construction there, in a town called Unterhaching.
That same issue of Monocle also points us to the "hexagonal wooden islands" of architect Vicente Guallart (whose work was previously seen on BLDGBLOG here).
This "astonishing series of artificial islands," Monocle writes, comes "in two basic forms – flat or 'hillock' – and [they] have been a great success with sunbathing locals." In the architect's own words, these create "multiple coastlines," extending seasonal fun onto previously nonexistent landforms.

This also raises the interesting question, though, of designer terrain – or even branded landscapes, specific earthen features associated with, say, Nike or the Hilton Hotel chain – and whether or not terrestrial augmentation, such as Guallart's hexagonal wooden islands, will be the next step in boutique design. Rather than a boutique hotel, in other words, you'd have a boutique landscape.
A bit further afield, meanwhile, "shape-shifting 'smart dust' may explore alien worlds," New Scientist reports.

Thousands of miniscule wireless sensors, or "smart dust", could one-day be used to explore other planets, swirling across the landscape by subtly altering their shape.

These individual pieces of "smart dust" will "navigate by shape-shifting," as they drift in artificial clouds of nanotechnology – implying, incredibly, that machines may someday form entire weather fronts, with their own microclimates and atmospheric effects – crossing extraordinary landscapes, such as the "outcrop called 'Olympia' along the northwestern margin of 'Erebus'," on Mars.

Finally, for now, it was announced this week that the US military "is building a three-mile concrete wall in the centre of Baghdad along the most murderous faultline between Sunni and Shia Muslims."

The wall, which recognises the reality of the hardening sectarian divide in Baghdad, is a central part of George Bush's final push to pacify the capital. Work began on April 10 under cover of darkness and is due for completion by the end of the month... Although Baghdad is full of barriers and checkpoints, particularly round the Green Zone where the US and British are based along with the Iraq government, this is the first time a wall has been built along sectarian lines. Its construction comes as the security situation appears to be deteriorating despite the recent US troop "surge".

The fact that physical structures, such as checkpoints and Bremer walls – in other words, pieces of architecture – are being used "to pacify" Baghdad fascinates me no end.

Adding to the tactical surreality of this decision – after all, building a wall to separate warring neighborhoods will almost certainly result in more extreme mortar attacks and general social distrust – we find this glimpse of architectural construction under continuous military guard:

The Baghdad wall, which will be 12ft (3.5 metres) high, is being built by US paratroopers who left Camp Taji, about 20 miles north of the city, on the first night in a dozen trucks carrying stacks of huge concrete barriers, each weighing 14,000 pounds (6,300kg). Cranes, protected by tanks, winched them into place. Building has continued every night since.

The ultimate "strategy" here is to create "a series of gated communities, in which US and Iraqi troops control entry and exits."
More soon – and happy Earth Day, by the way.
