Gold Fault Laser

In the general chaos of renovating a house here in Los Angeles, I missed this lecture and reception on Friday night, launching a semi-fictional “Geothermal Futures Lab” at SCI-Arc.

It involves installing a gold-plated laser somewhere deep in the San Andreas Fault to extract geothermal energy from the landscape. Think of it as a kind of gonzo version of the San Andreas Fault Observatory at Depth.

The press release, from architect Mark Foster Gage, is a great example of a solipsistic inventor’s imagination at full blast—featuring “geothermal resonance technologies,” nano-gold foil-wrapped laser components, an “experimental phenolic cured resin foam,” and so on.

The functioning of the equipment would also rely, at least partially, on existing “metal deposits along the strike-slipping continental plates,” bringing to mind both the naturally occurring nuclear reactors in Gabon and the giant Earth-battery cells circulating beneath the forests of central Canada: landscapes whose geochemistry lends them to these sorts of giant, speculative energy installations.

Or see Norway’s extraordinary Hessdalen lights, a geologically electrified valley that seems ripe for a Mark Foster Gage-like architectural-energy proposal.

In all these cases, of course, what’s also worth noting is that, as fantastic as this sort of facility might seem—whether it’s a lab extracting electrical energy from the San Andreas Fault, as Foster Gage suggests, or one positioned above geochemical differentials in the Canadian soil—as soon as the power it supplies can be made available through the national grid, it would immediately pass from some sort of absolutely bonkers sci-fi vision of the near-future to, frankly, something utterly mundane. It would simply be where the power comes from, and people would shrug it off as a mere utility (if they think about it at all).

But what this also means is that we might already, right now, be missing out on seeing the truly otherworldly nature of our own power-generation facilities, which have all too easily disappeared into the infrastructural background of the modern world. Science fiction is already here, in other words, we just tend to refer to it as infrastructure. See, for example, Crescent Dunes or PS10. Or, for that matter, take a harder look at oil.

In any case, here’s a sample from the project text, obligatory typos and all:

The exhibited technology capitalizes on the unique tungsten-saturated substrate of the San Andres fault through the use of a visible-light Q-switched Nd:YAG lasers, tuned to extract sustainable magno-electrical energy from a +678 degree Kelvin supercritical water deposits located adjacent to a stable magma chamber 4.4km beneath the Earths surface. This supercritical water, that behaves both as liquid and gas, is vaporized through 3,780 Kelvin bursts which at peak power induce a supercritical matter state releasing energy in exponential excess of its matter equivalent. The presence of heterogeneous frequency fields in metal deposits along the strike-slipping continental plates supercharges the pockets of supercritical water with magnetic nuons which are forced upwards with velocity µ as a result of the pressure gradient along the vertical faults. Due to the variable decay rate of metals in the presence of such high trajectory nuons, the prototype laser resonance mechanism itself is encased in an experimental phenolic cured resin foam (Cas no. 000050-00-0 with a normal specific gravity of 120 kg/m3) which insulates the process from outside magnetic interference. For rapid nuon decay protection the foam resin is additionally coated with the same seven µm micrometer nano-gold foil used to encase existing NASA satellites. This thick film of gold nano-molecules particles gives the machine its striking gold aesthetic appearance.

A nuon-resistant radiant machine buried in the San Andreas Fault, extracting energy from the friction between tectonic plates? With lasers? Yes, please.

The exhibition itself is up until March 4; stop by SCI-Arc to see more or check out the project’s website.

Conversion Moment

While we’re looking at work by Zecc Architects, it’s worth checking out their proposed renovation of a water tower in Utrecht.

A circular room with panoramic views of the city, and a modern fireplace in the center? Yes, please.

[Image: Proposal for a converted residential water tower in Utrecht, by Zecc Architects; rendering by 3D Studio Prins].

I even love where the tower’s original brick core is revealed, despite appearing in something as mundane as a restaurant.

[Image: Proposal for a converted residential water tower in Utrecht, by Zecc Architects; rendering by 3D Studio Prins].

As a very brief aside, meanwhile, one of many things that remains amazing to me about the architectural world today is that these sorts of buildings—grandiose brick megastructures, from water towers to old tobacco warehouses to classic New York brownstones—are immensely popular as domestic renovations or large-scale residential conversions, but they otherwise seem to be completely beyond the pale for architects to consider designing from scratch in the present day. Even when contemporary architects do take on such commissions, they seem to leave their creativity at the door.

As a former New Yorker, it always blew me away that incredible building stock existed in neighborhoods such as DUMBO—that is, huge warehouses featuring recessed arched windows, ornamented brick, and, at times, gorgeous exterior buttressing—or that even the most random online image search for historical warehouse districts pop up such incredible and evocative buildings. Yet there seems to be no appetite, either amongst developers or architects, to explore what architects could do with these same styles and languages today.

Even just imagining a 21st-century brick super-warehouse (or circular tower) built from scratch in New York City—or Boston, or Bermondsey, or Hamburg—featuring modern interiors and finishes, and designed to avoid the headaches of older building stock, makes my head swoon, and there is no doubt in my mind that elaborate, architecturally complex brick megastructures could be realized today without falling into kitsch or postmodern quotation. And there is also, in fact, no inherent reason why creating brickwork residential super-projects should lead to an emerging financial ecosystem for absent investors in the process.

But, hey: I’m not a real estate developer and I have no way to change the game.

Drawing Science/Drawing Fiction

I’ve been remiss in posting about a graduate course I’ll be co-teaching with the brilliant Nicholas de Monchaux up at UC Berkeley for the 2018-2019 academic year. The application period is currently open through December 2017.

Called “Drawing Science/Drawing Fiction: The Future of Californian Ecology,” the year-long Master’s course will be a combination of architectural design, experimental drawing methods, and narrative speculation, exploring what de Monchaux calls a “new relationship between architecture, media, ecology, and craft.”

The idea is to look ahead, not just at the future of California, but at the future of what California represents: cutting-edge industrial design, the global cinematic imagination, unparalleled demographic integration, agricultural innovation, adaptive infrastructure, and, of course, the risks of climate change.

With the entire state of California at their disposal, students will be able to focus on everything from the U.S./Mexico border to the San Andreas Fault, from Silicon Valley and space tourism to the sci-fi productions of Hollywood. Agriculture, Artificial Intelligence, electric cars; species loss, wildfire, drought; policing, governance, human labor.

There are architectural scenarios to design and explore for all of these.

In an interview with Boom California published in 2014, novelist Kim Stanley Robinson—who was also interviewed here on BLDGBLOG way back in 2007—commented on the science-fictional appeal of California. By the time he went to college, he remarked, the landscape of the state had fundamentally changed; it was being terraformed for human habitation by the forces of industry and suburban development.

California, he realized, was itself a design project.

[Images: From David Maisel’s “The Lake Project”; used with permission of the artist].

Robinson explained to Boom that, in the blink of an eye, California became a “completely different landscape. At that same time I started reading science fiction (…) and it struck me that it was an accurate literature, that it was what my life felt like; so I thought science fiction was the literature of California. I still think California is a science fictional place. The desert has been terraformed. The whole water system is unnatural and artificial. This place shouldn’t look like it looks, so it all comes together for me. I’m a science fiction person, and I’m a Californian.”

Science fiction is the literature of California.

[Image: Early rendering for Michael Maltzan’s Six Street Viaduct in Los Angeles].

Briefly, this theme was developed further by an essay by Michael Ziser published in the same issue of Boom. “Postwar science fiction is to a surprising degree a phenomenon of the western United States,” Ziser wrote. It was also quite specifically Californian.

“As the producers of Golden Age sci-fi were lured to the region by the new economic opportunities available to writers in the pulp, television, and film industries of Southern California,” Ziser continued, “they were also drawn into an imaginative relationship with California’s physical novelty as a place sprung de novo from the plans of hydraulic engineers, road builders, and tract housing developers.”

Many of the major themes of science fiction in this period—the experience of living in an arid Martian colony, the palpable sense of depending in a very direct way on large technological systems, unease with the scope and direction of the military and aeronautics industries, the navigation of new social rules around gender and race—can be read as barely veiled references to everyday life in California. For sci-fi writers, teasing out the implications of an era in which entire new civilizations could be conjured almost from nothing through astonishing feats of engineering and capital was a form of realism. They were writing an eyewitness account of what was the most radical landscape-scale engineering project in the history of the world.

This idea of an “imaginative relationship with California’s physical novelty” is something we will be exploring in architectural form throughout the Studio One experience. In the process, we will approach California itself as a subject of design and compare the state to other regions currently experiencing their own de novo re-inventions, whether it’s a thawing Arctic or China’s ongoing building boom.

To develop and articulate their visions, students will be pushed to experiment with new forms of architectural representation, modeling, and drawing—or, as de Monchaux writes, “Our chief medium will be drawing, but we will engage and embrace a world of devices and tools—from scripting through mapping and virtual reality-that are changing, and expanding, the capacity of architecture to influence the world.”

I will be up in the Bay Area multiple times for this throughout the academic year, although not on a full-time basis; if you’re a fan of de Monchaux’s work, of science fiction, of architecture, of design’s potential for conjuring radical visions of landscape futures, then please consider applying. You have roughly two more months to do so.

The Bartlett School of Architecture has made all three volumes of Fabricate, their excellent series of books and conference proceedings dating back to 2011, free to download.

[Image: Matter Design’s La Voûte de LeFevre, Banvard Gallery (2012)].

More than 700 pages’ worth of technical experiments, speculative construction processes, new industrial tools, and one-off prototypes, the books are a gold mine for research and development.

3D printers, buoyant robots, multi-axis milling machines, directed insect-secretion, cellular automata, semi-autonomous bricklaying, self-assembling endoskeletons, drone weaving—it’s hard to go wrong with even the most cursory skimming of each volume, and that doesn’t even mention the essays and interviews.

Download each book—from 2017, 2014, and 2011—and be prepared to lose a few days reading through them.

Arch History

[Image: Spiral Arches by Daydreamers Design].

A project I noted while serving as one of many, many design jurors this year for the Architizer A+Awards used a spiraling outdoor corridor of arches in the United Arab Emirates to tell the history of the Islamic arch.

[Image: Spiral Arches by Daydreamers Design].

The Hong Kong-based team behind the project, Daydreamers Design, explained that they organized the arches into ten typologies, then arrayed those into a much larger sequence, “in historical order.”

[Images: Spiral Arches by Daydreamers Design].

In other words, as you meander down the hallway, you also move forward—or backward—through arch history.

[Images: Spiral Arches by Daydreamers Design].

For what it’s worth, I’d love to see something similar done with Western design orders, or even cathedral buttresses.

In any case, the project did not win any A+Awards, but it remains noteworthy, nonetheless. Watch a short video of the project, below.

Inflatables Give Structure To Air

[Image: A project by Haus-Rucker-Co].

ONE
Three men with oversize briefcases show up in New York City. They drop their cases onto the sidewalk and leave them there, disguised amongst the workday crowds, several blocks away from one another, unattended. Ten minutes later, the cases pop open: a whirring sound is heard as small industrial fans begin to operate, inflating carefully packed chains of linked polyethylene structures. Buildings emerge, expanding out from each case until entire rooms and corridors block the street. No one knows how to turn the fans off. The buildings are growing, labyrinthine, turning corners now and halting traffic. A news helicopter captures the scene from above as the transparent walls of huge empty buildings made of air flash with the colored lights of police cars.

[Image: An “inflatable nested toroid structure” patented by NASA (PDF)].

TWO
A man toils for thirteen years, sending ever-more complex test diagrams off to polyethylene factories in Florida. He wants to know how much it would cost for them to manufacture these parts he’s been designing, and designing well: temporary inflatable rooms that link off from other rooms, multi-scalar gaskets able to withstand knife attacks, even strange, one-time entry points that can be resealed from within. A retired cargo pilot, he dreams of giving structure to air. He writes, Man can live on air alone!, and sketches obscene bulbous shapes on paper napkins to the discomfort of passing strangers.

[Image: Inflatable toroid test; via NASA/Wikipedia].

THREE
A building made of polyethylene and sealed air takes shape on a beach near Cape Canaveral. Tourists flock to it, taking selfies and filming short videos with their kids. But the midday sun is relentless; the structure is heating and the winds are picking up. Within two hours, the complex inflated shape begins to tremble and beat against the sand, until, accompanied by an audible gasp from the assembled crowd, it is sucked out to sea. It tumbles and rolls and rises through the sky, a spinning point reflecting glints of subtropical sunlight as it disappears over the Atlantic horizon. No one can say who it was, but all witnesses insist there was a man inside. Sure enough, smartphone video of the structure being lifted over the waves reveals a man bracing himself against the interior walls, bearing an expression somewhere between mania and glee. Two weeks later, French police find him, disoriented and unshaven, lacking his passport, at a seaside bar in Arcachon. “I have a very strange story to tell you,” he slurs, before falling off his seat.

The Walled City (10-Mile Version)

[Image: “The Walled City (10-Mile Version)” by Andrew Kudless/Matsys].

A new exhibition opens next week at the Hubbell Street Galleries in San Francisco, part of the California College of the Arts, called Drawing Codes: Experimental Protocols of Architectural Representation. The idea behind the group show is to look at “the relationship between code and drawing” (emphases theirs), or “how rules and constraints inform the ways we document, analyze, represent, and design the built environment.”

Drawing Codes is curated by Andrew Kudless and Adam Marcus, with Clayton Muhleman, and it features work by Erin Besler, Elena Manferdini, Jimenez Lai, the Oyler Wu Collaborative, Rael San Fratello, and many more.

As Kudless—of Matsys fame—pointed out to me over email, the curators “gave all of the participants a set of codes that they had to follow (e.g. all black and white, orthographic projection, 25″ x 25″, etc.),” using this set of constraints to, among other things, foreground differences in approach between each participating architect.

If everyone’s doing the same thing, then how each person does it becomes more revealing.

[Image: “Half-Hearted Diamonds” by Jimenez Lai/Bureau Spectacular].

Perhaps ironically, it was actually the drawing by Kudless himself—which I first saw on Instagram—that caught my interest.

Called “The Walled City (10-Mile Version),” that project imagines an entire metropolis that is nothing but one, continuous wall.

Kudless explained that it came about by posing himself a rhetorical question: “What would a city look like if it was a wall and nothing else? I’ve been fascinated with walls that have grown thick enough to be buildings in themselves. From medieval European city walls to the Great Wall in China, there is something really interesting about taking something that is ostensively about separating two territories and turning into an inhabitable space in its own right.”

[Image: Close-up from “The Walled City (10-Mile Version)” by Andrew Kudless/Matsys].

The results: a rule-constrained exploration of how a wall could become a city.

I started to play around with slowly increasing a wall’s length while preventing it from moving outside a site or intersecting itself. At a certain point in the growth process, the wall takes over the entire site. There is still an inside and outside to the wall, but sometimes the outside is deep inside the site boundary or vice versa. At that point, I was left with a big squiggly wall, but realized that I needed some sort of roofscape to make it read as a city and not just a thick wall. That’s when I turned to Google’s autocomplete feature to give me suggestions on what programs [spatial functions] a rooftop might support. I worked my way from A to Z pretty much accepting whatever suggestion Google’s autocomplete gave me and started designing parametric definitions that could implement that program on a number of different sites along the wall’s top.

The various social and architectural functions distributed around the massive roofscape included, for example, Rooftop Antenna, Rooftop Bar, Rooftop Cafe, Rooftop Deck, Rooftop Exhaust, Rooftop Film, Rooftop Garden, Rooftop Hotel Pool, and so on.

Interestingly, Kudless also pointed out that, if he were to run the same generative script again, it would likely produce “a similar, but not identical city,” and it would almost certainly not result in a wall exactly ten miles in length (which, in this case, was purely a coincidence, he explained).

In any case, I’ve been impressed by Kudless’s work for a long time; check out these older posts on his projects Nevada Sietch and robotic drawing protocols, for example, and then stop by the exhibition when it opens next week. There will be a reception on January 19 at 5:30pm at 161 Hubbell Street. More info.

“500 Years of Utopia” Opens

[Image: Thomas More’s Utopia].

There are two quick thing coming up this week that I wanted to post about:

1) At 7pm on Wednesday, November 9, I’ll be moderating a public conversation with an amazing group of Los Angeles-based designers, architects, and critics at USC’s Doheny Memorial Library. This is part of a larger evening, organized around the theme of “500 Years of Utopia.”

2016, after all, is the 500th anniversary of the publication of Thomas More’s book, and we’ll be launching a small exhibition looking back at More’s influence on political, urban, and even architectural thought—but more on that, below.

[Image: “500 Years of Utopia” title card; design by David Mellen].

Kicking things off at 7pm on Wednesday evening, Los Angeles Times architecture critic Christopher Hawthorne will be interviewing Alex Ross, music critic for the New Yorker and author of The Rest Is Noise: Listening to the 20th Century; they’ll be discussing the relationship between émigré composers in Southern California, the music of exile, and “utopian thought.”

This will be followed by a panel discussion featuring urbanist and landscape architect Mia Lehrer; games designer and critic Jeff Watson; architect and writer Victor Jones; and critic Christopher Hawthorne.

We’ll be looking at the role of utopia in contemporary design, with a specific focus on questions of access. We can talk about utopia all we like, in other words—but utopia for whom? In other words, if utopia is already here, who has access to it? Who has the right to design utopia? Who has the right to critique it?

[Image: Early type experiment for “500 Years of Utopia”; design by David Mellen].

Last but not least, we’ll hear from journalist and critic Claire Hoffman, who will introduce us to her newly published memoir Greetings from Utopia Park: Surviving a Transcendent Childhood.

The event is free and open to the public; however, please RSVP if you hope to attend. More information is available at that link, including parking, street address, and more.

[Image: Thomas More’s Utopia].

The second thing I wanted to mention, then, is in the same place and on the same evening, but at 5:30pm. We will be kicking off our brand new exhibition, in USC’s Doheny Memorial Library, called “500 Years of Utopia.”

For 500 years, utopia—a word coined by Sir Thomas More to describe the ideal city—has been used as popular shorthand for a perfect world and lies at the heart of the Western political imagination. But what does it really mean today in the context of 21st-century urbanism, especially in a megacity like Los Angeles that has been the setting for utopian and dystopian thinking almost since its founding? A new exhibition of materials from the USC Libraries’ collections explores these questions, the history of utopian thinking, and the fine line between utopia and dystopia.

In addition to a wealth of utopian/dystopian material taken directly from the USC Libraries, we’ve used an interesting graphic approach of overlaid, differently colored exhibition text, one (in red) offering a utopian interpretation of the media and objects on display, the other (in blue) offering a dystopian spin. Decoder glasses will be on hand to assist…

Please stop by for our opening reception at 5:30pm on Wednesday, November 9. It, too, is free and open to the public, and it segues directly into the event that kicks off at 7pm.

More information is available over at USC.

Local Code

[Image: Local Code by Nicholas de Monchaux].

Architect Nicholas de Monchaux—whom you might remember from, among other things, a long interview on BLDGBLOG a few years back—has a new book out this week.

[Image: Local Code by Nicholas de Monchaux].

Local Code is an exploration of design variants and latent possibilities in overlooked parcels of urban space. It is “as much design speculation as narrative (and as much obsession as exposition),” he explains.

[Images: Local Code by Nicholas de Monchaux].

The book includes no fewer than “3,659 drawings of designs (by me!) for vacant lots and spaces in New York City, Los Angeles, San Francisco, and the Venice Lagoon, highlighting how such spaces can play an essential and unique role in providing ecological, social, and cultural resilience. Inspired originally by Gordon Matta-Clark’s Fake Estates project, the book has become a graphic and intellectual meditation on cities, networks, data and resilience.”

[Image: Local Code by Nicholas de Monchaux].

The book’s thesis is that “vacant public land”—by which de Monchaux means everything from “land under billboards in Los Angeles, dead-end alleys in San Francisco, city-owned vacant lots in New York City, and abandoned islands in the Venetian lagoon”—actually contain “unrecognized potential as a social and ecological resource.” The accompanying explosion of drawings and diagrams is meant to tease out what some of these potentials might be.

Consider picking up a copy, check out the book’s introduction online, and don’t forget to click back to BLDGBLOG’s interview with de Monchaux about the design history of the Apollo spacesuit.

Totemic Elevator

[Image: The Barakka Lift, Malta, by Architecture Project; Instagram by BLDGBLOG].

While in Malta last week, I stumbled on the Barakka Lift outdoor elevator, a project I’d written about here but had forgotten was in the city of Valletta. It was a pleasant surprise.

Designed by local firm Architecture Project, the lift connects two very different vertical levels of the metropolis, rising like a fortified tower to bring visitors to and from a small garden on the walls of Valletta.

[Image: The Barakka Lift by Architecture Project; Instagram by BLDGBLOG].

One of my favorite urban sights is the unfinished concrete elevator cores of under-construction high-rises. Monolithic, sharply defined, and almost always undecorated—such as this random example—they are pure concrete geometry rising above foundation piles and machinery—elevators that appear before their buildings have arrived.

The Barakka Lift is obviously different, in that it adds an exterior skin of perforated metal to hide the shaft of the lift itself, but it also divorces the idea of the elevator from any building it would normally be contained by. It connects two outsides, sewing one level of the city to another.

As such, it suggests that lifts, like bridges, are just another possibility for urban transportation—vertical pedestrian movement through space—and that lifts are not really interiors at all, in fact, but public spaces we can all use or inhabit.

There’s also something so interesting in the notion of a 21st-century elevator shaft stylized to look more like a 17th-century fortification by way of a near-future science fiction film.

In any case, better photos of the project can be seen in this earlier post. If you’re ever in Malta, be sure to check it out; you’ll find it here.

Please Don’t Take My Photochrome

It’s easy to lose time clicking through the Library of Congress photochrome—or photochrom—collection.

Each image has a strangely volumetric beauty, enhanced by subtle depths of shade, that results from a development and printing process that also produced these otherworldly intensities of color.

I could look at these all day—these old streets and roofscapes, honey-colored rocks and even brilliant white robes glowing with sunlight.

It’s also interesting to watch as small moments of modernity pop-up in the landscape, like funiculars or—in other images not included here—cable railways, train stations, and steamships.

05105v [Image: Cable railway, Marseille, France; via Library of Congress].

In other cases, it’s just the pure bulk of masonry and its interaction with sunlight that remains so visually compelling, where looking at the city almost meant looking at a geological formation, an artificial mountain chain that you knew was filled with rooms and hallways waiting to be explored.

Finally, these old, looming roof profiles from buildings in Germany are spectacular.

Architects and engineers today should spend more time thinking about roofs, as spaces that can be inhabited, not merely as minimal surfaces used for no other purpose than to cover another space.

Roofs should be labyrinths you can walk through and get lost within. Roofs should have dimension; they should have windows and rooms. They should be spaces in their own right, not just lines where other spaces end.
