Straw is the ultimate environmentally-friendly building material since it is renewable and is a by-product of farming.

The crop used for the straw can be grown locally, and because it absorbs as it grows, buildings made from it can be seen as having zero, or even a negative carbon footprint.

Also, due to its high insulating properties, houses made of straw bales need almost no conventional heating, keeping running costs low and minimising.

The research team will be assessing straw bales and hemp as building materials so that they can be used more widely in the building industry for housing, helping the UK achieve its targets for reducing .

The two storey BaleHaus to be built on campus will be made using ‘ModCell’ – pre-fabricated panels consisting of a wooden structural frame infilled with straw bales or hemp and rendered with a breathable lime-based system.

ModCell is the creation of White Design in Bristol and Integral Structural Design in Bath. Other partners on the research project are Agrifibre Technologies, Lime Technology, Eurban, the Centre for Window & Cladding Technology and Willmott Dixon.

Some of the building has already appeared in the media spotlight. Last year the team helped Kevin McCloud, presenter of Channel 4’s Grand Designs programme, to build an eco-friendly house in six days using ModCell panels for the Grand Designs Live exhibition.

All the wall panels used for the ground floor of the Grand Designs house are being reused for the BaleHaus at Bath.

<Editorial commentary>

So, I guess this means that, yet again, Science is catching up with common sense. Given the old maxim that “Science changes one funeral at a time” it’s then reasonable to presume that someone IMPORTANT must have died. On a lighter note, the combination of straw and hemp is highly appropriate for Mendocino County in particular and northern California in general. Moreover, no matter how commonsensical a technology may be, there’s nothing like a couple (hundred) PhD research papers to legitimize it in the eyes of bankers, lenders, and engineeres. This and other similar efforts could make it easier to get approval for “alernative” methods from agencies, institutions and the powers the be. I call it a good thing.

Pacific Northwest forests could store more carbon, help address greenhouse issues

July 2nd, 2009 PhysOrg.com

The forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in coming years, a recent study concludes, if they are managed primarily for that purpose through timber harvest reductions and increased rotation ages.

In the complete absence of stand-replacing disturbances – via fire or timber harvest – forests of Oregon and Northern California could theoretically almost double their  storage.

Although it isn’t realistic to expect an absence of disturbance, the estimates were based on average conditions up until now that include variation in forest, age, climate, disturbances and soil fertility. If all forest stands in this region were just allowed to increase in age by 50 years, their potential to store  would still increase by 15 percent, the study concluded.

That would be a modest, but not insignificant offset to the nation’s carbon budget, scientists say, since this region accounts for 14 percent of the live biomass in the entire United States.

The findings were made by scientists in the College of Forestry at Oregon State University, as the result of almost two decades of analysis of 15,000 inventory plots in a large region, through several different projects, as part of the North American Carbon Program. The scientists, who said they have often been asked what the theoretical potential was for storing carbon in these forests, conducted the analysis using inventory data that captured current variation in biomass due to many factors

Emerald Empire Adventures is proud to wholeheartedly support Al Gore’s Repower America campaign for 100% renewable energy in 10 years.

The content below is reproduced here from http://www.repoweramerica.org/state/california/ as a public service.

We’re more than 262,031 members strong in California

Did You Know?

  • California is the leading producer of renewable energy in the United States. It ranks 1st in the nation for solar PV, solar thermal, geothermal, and bio-power capacity.It also ranks 3rd in the nation for installed wind capacity.
  • California is home to the largest single source of solar energy in the world: a 354 MW solar thermal facility in the Mojave Desert.The state will shatter its own record in 2011 when a 553 MW solar thermal facility built by Solel begins operation, also in the Mojave Desert.According to researchers at the National Renewable Energy Laboratory, California’s total solar thermal potential is equal to 12 times the state’s current electricity capacity.
  • California’s potential geothermal resources can power every home in the state.The state’s potential unconventional geothermal resources could power another 54 million homes.

Clean energy jobs in California

California is at the forefront of electricity generation from non-hydroelectric renewable energy sources, and its policies and investments encourage strong job growth in a clean energy economy. A few companies are already taking part in this new economy by providing ‘green’ jobs.

For example, FPL Group is set to operate its 250-megawatt solar thermal energy plant near Kern County, which will employ roughly 1,000 workers in its operation. And reports estimate that more jobs could be on the way. One study says that $12.7 billion investment on deploying renewable energy and energy efficiency in the Golden State can create 235,000 jobs over two years. And, this study only captures a portion of the service, construction, and technology jobs that will be created in the state by truly Repowering America.

(AP) — On a steep slope of the Rogue River-Siskiyou National Forest, a crew of young men with chain saws and hardhats worked their way through an old neglected clearcut, cutting brush and young trees and piling the remains to be burned later.

Freshly trained and closely supervised, the crew took care to leave behind volunteer sproutings of dogwood, madrone and huckleberry as well as the sugar pine and Douglas fir planted here 20 years ago. The pattern is designed to grow into a healthy forest less vulnerable to wildfire and better for fish and wildlife, rather than just turn out timber.

The House Hope Stewardship Project, taken off the shelf with $1.4 million from President Barack Obama’s , will thin and restore 890 acres.

It’s a tiny fraction of the 60 million to 80 million acres the U.S. Forest Service estimates need it nationwide, but people here feel as if this is a start – not only to grappling with the growing threat of wildfire in a warming climate, but in healing rifts between environmentalists, the timber industry and the Forest Service that have left the national forests in limbo.

“I wouldn’t go so far as to say there is peace in the valley, but we are closer than ever before,” said Shane Jimerfield, director of the Siskiyou Project, a local  group that grew out of the protests.

The national forests of the Northwest became a crucial national lumber source after World War II when the baby boom fueled a huge demand for new houses. But by the 1980s scientists began to worry that species like the northern spotted owl and some salmon were headed for extinction due to a loss of habitat.

Environmentalists won court orders stopping that logging, and the Clinton administration came up with the Northwest Forest Plan in 1994, which cut logging by more than 80 percent and set aside huge areas for fish and wildlife habitat. After President George W. Bush was elected in 2000 his administration tried to dismantle the Northwest Forest Plan and increase logging but was repeatedly blocked by more court rulings.

Please join Mendocino Area Parks Association’ s Carolyne Cathey and other park supporters and visitors 1:00PM today – Saturday June 20 – at 1:00PM beside the Ford House on Mendocino Headlands. The issues may not be clear to all of us, and this is your chance to hear what is going on with the state parks funding and how critical our voices are right now.
Enjoy some music and stop in the Ford House for a tour of this historic house on the headlands.

The only hope we have left to keep the parks open is to encourage all the voters in the state to contact their Senators, Representatives, and the Governor and ask for their “Yes” vote on a new funding stream to support our state parks — a $15/year per vehicle State Park Access Pass added to our car registrations. The Republican Caucus in both the Senate and the House, and the Governor, oppose this concept. With a SPAP, any of us with a California registered vehicle will have free day use, no matter how many times we entered the Parks.

To her credit, Assemblywoman Patty Wiggins not only supports funding for state parks, but she had already taken a salary cut, and reduced her per diem reimbursement for living expenses in Sacramento. Senator Wes Chesbro is also a strong support of parks.

Without some funding mechanism in this budget round, Parks will close. Businesses will be hurt when visitors stop coming because the campgrounds are closed, the restrooms are locked, the litter piles up and the roads are barricaded. Park properties will suffer right here where we live
and all over the state.

Please come and listen, and lend your support to help keeps our
parks open.

I am only a member of one MCN community list, Fort Bragg. If you would be so kind, we would appreciate it if you would send this message to the other local community lists as well.

Thank you,

'Milking' microscopic algae could yield massive amounts of oilEnlarge

Scientists in Canada and India are proposing a surprising new solution to the global energy crisis —“milking” oil from the tiny, single-cell algae known as diatoms, renowned for their intricate, beautifully sculpted shells that resemble fine lacework. Their report appears online in the current issue of the ACS’ bi-monthly journal Industrial Engineering & Chemical Research.

Richard Gordon, T. V. Ramachandra, Durga Madhab Mahapatra, and Karthick Band note that some geologists believe that much of the world’s crude oil originated in diatoms, which produce an oily substance in their bodies. Barely one-third of a strand of hair in diameter, diatoms flourish in enormous numbers in oceans and other water sources. They die, drift to the seafloor, and deposit their shells and oil into the sediments. Estimates suggest that live diatoms could make 10−200 times as much oil per acre of cultivated area compared to oil seeds, Gordon says.

“We propose ways of harvesting oil from diatoms, using biochemical engineering and also a new solar panel approach that utilizes genetically modifiable aspects of biology, offering the prospect of “milking” diatoms for sustainable energy by altering them to actively secrete oil products,” the scientists say. “Secretion by and milking of diatoms may provide a way around the puzzle of how to make that both grow quickly and have a very high content.”

From Foreign Policy Magazine an interesting look at the implications and historical contest of our current econ0mic situation;

“AS NIKOLAI KONDRATIEV SHIVERED before his executioners on a wintry Siberian morning in 1938, he could scarcely have imagined that, 71 years later, his name would be resurrected by a new generation of business theorists and management gurus seeking to understand the first Great Recession of the 21st century.

A prime mover behind Lenin’s 1921 New Economic Policy, which briefly rehabilitated capitalism in order to save a young Soviet Union from imminent collapse, Kondratiev was an intellectual insurgent in a time and place where heresy could get one killed. Kondratiev theorized that economic activity took place in long waves: 50- or 60-year periods of creativity and growth followed by briefer contractions, after which the cycle would begin anew.

So taken was Joseph Schumpeter, the Harvard University economist best known for coining the term “creative destruction,” with the idea of long waves that he named the concept for Kondratiev. Schumpeter’s view was that innovation tends to arrive in clumps: “discrete rushes which are separated from each other by spans of comparative quiet.” These bursts of creativity, he wrote, “periodically reshape the existing structure of industry by introducing new methods” of production, organization, and supply. As for the negative effects of depressions—unemployment, the loss of wealth, economic dislocation—they were just creative destruction at work.”

Fire Mitigation Work In Western US Misplaced, Says New Study

ScienceDaily (June 15, 2009) — Only 11 percent of wildfire mitigation efforts undertaken as a result of a long-term federal fuels-reduction program to cut down catastrophic wildfire risk to communities have been undertaken near people’s homes or offices in the past five years, says a new study led by the University of Colorado at Boulder.

The analysis of the U.S. National Fire Plan shows that as more Americans live in or near fire-prone forests and more wildfires burn, most federally funded activities to reduce fuels and wildfire hazard have occurred far from the “wildland-urban interface,” the area prioritized by federal wildfire policies. The result suggests that federal wildfire treatments are minimally effective at mitigating the threat of wildfire to homes and people in the western United States.

The study also suggests that future fire mitigation strategies should emphasize constructing and maintaining “firewise” homes, restricting the abundance and configuration of residential housing units near wildlands susceptible to fire, and improving cooperation among private and public landowners in implementing fire mitigation treatments and in paying for fire suppression.

“Our comprehensive analysis suggests that fire mitigation treatments do not effectively target the wildland-urban interface,” said Tania Schoennagel, a research scientist in CU-Boulder’s geography department.

Schoennagel led a team of researchers who examined 44,000 federally funded wildfire mitigation projects in 11 western states between 2004 and 2008.

Schoennagel’s team is the first to evaluate the U.S. National Fire Plan’s management activities across the West, and to compare the location of fire-mitigation treatments to the wildland-urban interface and its nearby surroundings. The team’s findings will be published in the June 8 edition of the Proceedings of the National Academy of Sciences.

Co-authors on the study included CU-Boulder graduate student Teresa Chapman, the University of Montana’s Cara Nelson and Gunner Carnwath and Colorado State University’s David Theobald. The study was funded by the National Science Foundation and the Wilburforce Foundation.

The team found that only 11 percent of fuel-reduction activities took place within about 1.5 miles of the wildland-urban interface, where fires pose the greatest risk to homes and people. At the same time, most of the treated land was more than 6 miles from this high-risk zone.

PhysOrg.com May 28th, 2009All the carbon counts

 

Policies that turn forests into valuable carbon storage units would likely preserve forests and lower costs of cutting atmospheric carbon dioxide.

Cutting down forests for agriculture vents excess carbon dioxide into the air just as industrial activities and the burning of fossil fuels do. But whether policies to stabilize greenhouse gases in the atmosphere should include this terrestrial source of carbon dioxide is under debate. According to a new study this week in Science, failing to include land use changes in such policies could lead to massive deforestation and higher costs for limiting carbon emissions.

The results also suggest improved agricultural technology will be as important as new energy technologies in a carbon-limited future.

To understand the effects of economic forces from  on terrestrial carbon and land use changes, researchers with the Joint Global Change Research Institute in College Park, Md., a collaboration between the Department of Energy’s Pacific Northwest National Laboratory and the University of Maryland, used an integrated assessment model called MiniCAM to compare different scenarios. This computer model incorporates economics, energy, agriculture, land-use changes, emissions and concentrations of  in order to understand the way that human decisions interact with natural processes that control climate.

For this study, the researchers set the highest concentration that  could reach. Then they compared two ways to stay within that limit: in one, they taxed terrestrial  and industrial and fossil fuel emissions all at the same rate. In the other, they only taxed emissions from industry and .

Ignoring terrestrial carbon led to nearly complete loss of unmanaged forests by 2100, largely as a result of massive expansions of bioenergy crops — those planted to reduce the use of fossil fuels — replacing forests. However, placing a value on terrestrial carbon emissions led to increased forest cover, while bioenergy still expanded considerably compared to today.

“When society tries to limit carbon dioxide concentrations, if terrestrial carbon emissions aren’t valued but fossil fuel and industrial emissions are, economic forces could create very strong pressures to deforest,” said PNNL scientist Marshall Wise, the study leader.

In addition, the cost to reduce global emissions in a world that valued terrestrial, fossil fuel, and industrial sources dropped to half that of the world in which only fossil fuel and industrial entities paid to emit carbon. This suggests that storing carbon in forests, agricultural areas, and other ecosystems is an important and cost-effective part of a bigger carbon dioxide emissions control strategy that includes dramatic changes to the global energy system.

This study also shows that continual improvement in agricultural crop productivity for crops like corn, wheat, barley, and rice will be required to best make use of limited cropland. This suggests improvements to agriculture technology could be as important as improvements to energy technology in controlling .
