PORTLAND, Ore. — Urban gardening used to seem subversive. People planted tomatoes in public parks, strung their hops to rooftops to make homebrew and reclaimed empty lots as community farms, never mind the property owner.
Yet here in one of the more thoroughly tilled cities in America, subversive has come full circle: the federal government plans to plant its own bold garden directly above a downtown plaza. As part of a $133 million renovation, the General Services Administration is planning to cultivate “vegetated fins” that will grow more than 200 feet high on the western facade of the main federal building here, a vertical garden that changes with the seasons and nurtures plants that yield energy savings.
“They will bloom in the spring and summer when you want the shade, and then they will go away in the winter when you want to let the light in,” said Bob Peck, commissioner of public buildings for the G.S.A. “Don’t ask me how you get them irrigated.”

GUSTINE, Tex. — Day and night, a huge contraption prowls the grounds at Frank Volleman’s dairy in Central Texas. It has a 3,000-gallon tank, a heavy-duty vacuum pump and hoses and, underneath, adjustable blades that scrape the surface as it passes along.
In function it is something like a Zamboni, but one that has crossed over to the dark side. This is no hockey rink, and it’s not loose ice being scraped up. It’s cow manure.
Lots of cow manure. A typical lactating Holstein produces about 150 pounds of waste — by weight, about two-thirds wet feces, one-third urine — each day. Mr. Volleman has 3,000 lactating Holsteins and another 1,000 that are temporarily “dry.” Do the math: his Wildcat Dairy produces about 200 million pounds of manure every year.
Proper handling of this material is one of the most important tasks faced by a dairy operator, or by a cattle feedlot owner, hog producer or other farmer with large numbers of livestock. Manure has to be handled in an environmentally acceptable way and at an acceptable cost. In most cases, that means using it, fresh or composted, as fertilizer. “It’s a great resource, if used properly,” said Saqib Mukhtar, an associate professor of biological and agricultural engineering at Texas A & M University and an expert on what is politely called manure management.

Two kelp farmers in Maine hope to get a piece of a $7-billion global seaweed industry.
Reporting from Falmouth, Maine – Paul Dobbins and Tollef Olson admit they still have a kink in their scheme to use seaweed to revolutionize American eating habits, clean the environment, lower the federal trade deficit and make themselves fabulously rich.
Call it the yuck factor.
“It tastes better than it looks,” said Olson, holding a shimmering frond of brown horsetail kelp he had just plucked from the cold gray waters of Casco Bay. “Really.”
Dobbins and Olson run what is believed to be America’s only commercial kelp farm. Inspired by mega-aquaculture sites in Asia, and a $7-billion global seaweed industry, the two entrepreneurs started cultivating kelp here last year and have begun marketing it as an exotic frozen vegetable.
“It’s a giant brown algae in the water, but it turns bright green when it’s cooked,” Olson said. “Think kelp noodles. And kelp salad. And kelp slaw.”

Lots of cities have farmers markets, but most — if not all — of the produce comes from rural farmers that use oil-intensive methods of transportation to cart around their food. With 80% of all people on the planet projected to live in cities by 2050, food production will have to move into cities if it is to remain cost-efficient. A Swedish-American company called Plantagon has conceived of an incredible solution: a massive urban greenhouse contained within a geodesic dome. The vertical farm, which consists of a spiral ramp inside a spherical dome, is currently in the development stages.

Thanks to 15 year old Texan Javier Fernández-Han, we feel a little more hopeful about the next generation’s ability to adapt to a world of limited resources. The high school student developed a fully featured algae-powered energy system that combines a dozen new and existing technologies to treat waste, produce methane and bio-oil for fuel, produce food for humans and livestock, sequester greenhouse gases, and produce oxygen. Dubbed the VERSATILE system, the project is this year’s winner of the annual Invent Your World Challenge $20,000 scholarship.

Metropolis’s 2009 Next Generation competition received scores of entries, from which this year’s jury chose one winner and eight runners-up to be recognized in the May issue of the magazine. But there were far more than just nine good ideas in the bunch. The judges also selected 12 “notables”—entries that, for various reasons, fell short of the final selection, but that the jurors felt still deserved recognition. To that end, we will be posting one notable Next Generation proposal every Thursday for the next three months. In doing so, we hope to foster discussion that will help the teams refine their ideas, connect with like-minded readers, and perhaps even implement their projects in the real world.
This week: Emilio Ramirez’s proposal, Feeding the Addiction: The Emergence of the Single Family Power Plant, which envisions a low-cost, renewable energy production and delivery system that could turn homes and businesses into self-sustaining energy producers. How would it work?
According to Ramirez, a private energy company would design, fabricate, and install the mini power plants, which would concentrate solar heat on a collector plate to boil a fluid and create steam. That steam then turns a turbine engine that rotates an alternator for an estimated daily output of 84 kilowatt hours.

“Voluntourism” ramps the ecological impulse up a notch, providing ways for vacationers to help save the world’s sustainable resources.
Rain forests and tundra, deserts and savannas, mountaintops and undersea reefs. No spot on the planet is too remote for the movement that has changed the face of leisure travel. Ecotourism, in all its various guises—green tourism, sustainable tourism, adventure travel—has gained traction as enthusiasts seek to experience the earth’s wonders while treading lightly on them.
Lately a new subset of this boom has emerged. “Voluntourism” ramps the ecological impulse up a notch, providing ways for vacationers to help save the world’s sustainable resources. The trend has been described as a kind of mini version of the Peace Corps. Depending on your interests, you could find yourself repairing trails leading to Old Faithful, tracking sharks in the Atlantic, or mixing cement for housing in the Andes. Voluntourism is becoming a significant growth sector of the travel industry. Online trip planner Travelocity, for example, now partners with tour operators such as GlobeAware, Cross-Cultural Solutions and Take Pride in America, which specialize in launching voluntourists on service-oriented vacations.

Filthy coal-fired power plants spew carbon into the air. A mish-mash of 9,200 generators streams vital electrons along 300,000 miles of aging, inefficient transmission lines and one untrimmed tree in the wrong place could plunge a quarter of the country into darkness. This is our electric grid. A whopping 40 percent of all the energy used in the US—be it oil, gas, wind, or solar—is converted into electrons that travel over these wires. Any attempt at energy reform must begin here.
But this keystone of our 21st-century economy has yet to advance much beyond its 19th-century roots. Considering how wasteful, unresponsive, and just plain dumb the grid is, it isn’t surprising that outages—which have been increasing steadily over the past quarter century—cost us $150 billion a year. The real shock is that the damn thing works at all.
Now consider what we will ask the grid to handle in the near future: Demand for electricity is expected to increase by as much as 40 percent in the next two decades—more than twice the population growth rate. To meet that need, we will have to generate an additional 214 gigawatts, a feat that would require the construction of more than 357 large coal plants. We also want to plug in dozens, if not hundreds, of gigawatts of wind and solar power harvested from the most remote corners of the country. And we will want to recharge millions of electric vehicles every night, without fail.

Soaring above the Mississippi River just east of downtown Minneapolis is one remarkable concrete job.
There on Interstate 35W, the St. Anthony Falls Bridge carries 10 lanes of traffic on box girders borne by massive arching piers, which are supported, in turn, by footings and deep pilings.
The bridge, built to replace one that collapsed in 2007, killing 13 people, is constructed almost entirely of concrete embedded with steel reinforcing bars, or rebar. But it is hardly a monolithic structure: the components are made from different concrete mixes, the recipes tweaked, as a chef would, for specific strength and durability requirements and to reduce the impact on the environment. One mix, incorporated in wavy sculptures at both ends of the bridge, is designed to stay gleaming white by scrubbing stain-causing pollutants from the air.
The project, built for more than $230 million and finished in September, three months ahead of schedule, “might have been the most demanding concrete job in the United States in 2008,” said Richard D. Stehly, principal of American Engineering Testing, a Minneapolis firm that was involved in the project. It is a prime example of major changes in concrete production and use — changes that make use of basic research and are grounded, in part, in the need to reduce concrete’s carbon footprint.

THE country has fallen on hard times, but those of us who love cities know we have been living in the dark ages for a while now. We know that turning things around will take more than just pouring money into shovel-ready projects, regardless of how they might boost the economy. Windmills won’t do it either. We long for a bold urban vision.
With their crowded neighborhoods and web of public services, cities are not only invaluable cultural incubators; they are also vastly more efficient than suburbs. But for years they have been neglected, and in many cases forcibly harmed, by policies that favored sprawl over density and conformity over difference.
Such policies have caused many of our urban centers to devolve into generic theme parks and others, like Detroit, to decay into ghost towns. They have also sparked the rise of ecologically unsustainable gated communities and reinforced economic disparities by building walls between racial, ethnic and class groups.
Correcting this imbalance will require a radical adjustment in how we think of cities and government’s role in them. At times it will mean destruction rather than repair. And it demands listening to people who have spent the last decade imagining and in many cases planning for more sustainable, livable and socially just cities.
The changes needed may seem extravagant, but they are not impossible. Many of those who see the current economic crisis as a chance to rebuild the country’s infrastructure have pointed to previous major government public works projects, like Franklin D. Roosevelt’s Works Projects Administration in the 1930s and 1940s and Dwight D. Eisenhower’s 1956 National Interstate and Defense Highways Act, as a reminder of what this country was once capable of.
