(WebUrbanist) Outdoor advertising is so ubiquitous in almost every urban setting around the world, it’s difficult to walk down a street, take an escalator or sit on a bench without getting slapped in the face with one product or another. But the city of São Paulo, Brazil is like an advertising ghost town: all of its billboards stand oddly blank and empty.
In September of 2007, the world’s fourth-largest metropolis was scrubbed of almost every type of outdoor advertising – even pamphlets. It’s all part of mayor Gilberto Kassab’s quest to eliminate visual clutter, making the city itself the focal point rather than colorful, increasingly desperate marketing campaigns.
(Washington Post) Three key senators are engaged in a radical behind-the-scenes overhaul of climate legislation, preparing to jettison the broad “cap-and-trade” approach that has defined the legislative debate for close to a decade.
The sharp change of direction demonstrates the extent to which the cap-and-trade strategy — allowing facilities to buy and sell pollution credits in order to meet a national limit on greenhouse gas emissions — has become political poison. In a private meeting with several environmental leaders on Wednesday, according to participants, Sen. Lindsey O. Graham R-S.C., declared, “Cap-and-trade is dead.”
Graham and Sens. John F. Kerry D-Mass. and Joseph I. Lieberman I-Conn. have worked for months to develop an alternative to cap-and-trade, which the House approved eight months ago. They plan to introduce legislation next month that would apply different carbon controls to individual sectors of the economy instead of setting a national target.
According to several sources familiar with the process, the lawmakers are looking at cutting the nation’s greenhouse gas output by targeting, in separate ways, three major sources of emissions: electric utilities, transportation and industry.
(Washington Post) Jess Parker hugs trees. In the woods of Anne Arundel County, he throws his arms around tulip poplars, oaks and American beeches, and holds them so tightly that his cheek presses into their bark. This is not some hiker on a lark: anybody, hopped up on campfire coffee and exercise endorphins, might hug a tree once.
This is science. Parker has done it about 50,000 times. Parker, a forest ecologist at the Smithsonian Institution, has spent the past 22 years on a research project so repetitive, so time-consuming, that it impresses even researchers with the patience to count tree rings. Since 1987, he and a group of volunteers have embraced thousands of trees, slipped a tape measure behind them, and wrapped it around to measure the trees’ girth.
This year, after about 250,000 hugs between them, the work paid off. Parker’s data, which showed the trunks gradually fattening over time, indicated that many of the trees were growing two to four times faster than expected. That raised questions about climate change’s impact on the age-old rhythms of U.S. forests.
Today, 92 percent of all Americans want our country to develop solar energy resources, and 77 percent believe the federal government should make solar power development a national priority.That is why I was joined by 10 of my colleagues Senators Whitehouse, Cardin, Gillibrand, Merkley, Lautenberg, Leahy, Boxer, Menendez, Specter, and Harkin in introducing the Ten Million Solar Roofs Act.
The bill is all of 9 pages and is pretty straightforward. It calls for 10 million new solar rooftop systems and 200,000 new solar water heating systems over the next 10 years. When fully implemented, this legislation would lead to 30,000 megawatts of new photovoltaic energy, triple our total current U.S. solar energy capacity. It will increase by almost 20 times our current energy output from photovoltaic panels.
The legislation will rapidly increase production of solar panels, driving down the price of photovoltaic systems. It also would mean the creation of over a million new jobs. The passage of this bill would dramatically reorient our energy priorities and would be a major step forward toward a clean energy future for the United States.
Aerogels are made by removing the liquid from gels, resulting in a material that is more than 90 percent air. The porous structure of that nanomaterial makes it difficult for heat to pass through. As a result, aerogels make very good and light-weight insulators.
Because of costs, aerogel manufacturers have focused on high-end industrial applications, such as insulating oil and gas pipelines and even the Mars Rover spacecraft.
But now, a handful of aerogel companies are offering thin blankets that serve as replacements for traditional fiberglass, foam, or cellulose insulation. It’s still more expensive upfront but the costs have fallen to the point that it can make sense in certain cases, particularly masonry or curved walls, according to Aspen Aerogels.
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.”

In households across the country, green lines are being drawn between those who insist on wild salmon and those who buy farmed, those who calculate their carbon footprint and those who remain indifferent to greenhouse gases.
“As the focus on climate increases in the public’s mind, it can’t help but be a part of people’s planning about the future,” said Thomas Joseph Doherty, a clinical psychologist in Portland, Ore., who has a practice that focuses on environmental issues. “It touches every part of how they live: what they eat, whether they want to fly, what kind of vacation they want.”
While no study has documented how frequent these clashes have become, therapists agree that the green issue can quickly become poisonous because it is so morally charged. Friends or family members who are not devoted to the environmental cause can become irritated by life choices they view as ostentatiously self-denying or politically correct.
Solar-powered drip irrigation systems significantly enhance household incomes and nutritional intake of villagers in arid sub-Saharan Africa, according to a new Stanford University study to be published in the Proceedings of the National Academy of Sciences (PNAS). The study found that solar-powered pumps installed in remote villages in the West African nation of Benin provide a cost- effective way of delivering much-needed irrigation water, particularly during the long dry season. The results are scheduled to be published the week of Jan. 4 in the online edition of PNAS.
(LA Times) ESolar Inc. of Pasadena signed an agreement Friday to build a series of solar thermal power plants in China with a total capacity of 2,000 megawatts, in one of the largest renewable energy deals of its kind.
Coming four months after an Arizona company, First Solar, secured a contract to build an equally large photovoltaic power plant in China, the ESolar deal signals China's emergence as a major market for renewable energy.
“They’re moving very fast, much faster than the state and U.S. governments are moving,” said Bill Gross, ESolar’s chairman and the founder of Idealab.
TAIPEI (REUTERS) Canadian-born John Lamorie and his Taiwanese wife, Shelly Wu, used more than 1,000 kg of newspapers, many collected from students who would turn them over for points in class, to build the 75 sq-meter schoolhouse.
After getting the idea from visiting friends, Lamorie said he built a blender using a truck bed and a lawnmower blade. Into it he fed newspapers, water and cement to form what he calls “Papercrete,” the backbone of his six-inch thick school walls.
The schoolhouse’s walls are coated with a silicone coating to guard against rain damage. The school can accommodate about 16 students.
