Wanted: Smart Workers for Smart Grid

Early this week, President Obama gave a speech touting the $3.4 billion in grants the federal government has awarded to local companies, utilities and cities working to improve the country’s aging and outmoded electric energy grid. The awards will support “smart grid” technology that enables easier and more effective transmission of electricity from one region to another. So, what is a smart grid and how do we build it? If you have the time, I highly recommend a presentation by Roger Levy of the Smart Grid Technical Advisory Project based at the Lawrence Berkeley National Laboratory. Levy gave the presentation at last month’s meeting of the Oregon Public Utility Commission. More>

Feds: No link yet between drywall, health problems

Federal officials have not linked Chinese drywall to health problems and metal corrosion yet, despite homeowners' and politicians' criticism and initial laboratory test results released Thursday. Those tests showed the imported drywall has more sulfur and strontium, and emits higher rates of volatile sulfuric compounds than comparable North American wallboard. But officials called those tests limited, saying at least another month of study is needed before they can say whether Chinese drywall is causing homes' corroded pipes and electrical outlets, foul odors, and runny noses, sore throats and other health problems. Further testing by Lawrence Berkeley National Laboratory found that the Chinese samples emitted volatile sulfur compounds at a rate 25 times faster than the North American samples. More>

Berkeley Lab receives US$7m for enhanced geothermal energy technologies

As the world’s energy needs grow ever greater, scientists are charged with finding new ways to expand clean-energy resources and tap new ones. One such resource is geothermal energy, or heat mining, in which the heat acquired by fluid circulation deep in the Earth’s crust is tapped for conversion to electricity. Lawrence Berkeley National Laboratory has been awarded $7 million in American Recovery and Reinvestment Act funding for four projects that seek to advance Enhanced Geothermal Systems (EGS), which is capable of harnessing the Earth’s heat where conventional geothermal technologies cannot. The funding is part of a $400 million investment that the Department of Energy has made in geothermal energy thanks to the Recovery Act. More>

Cleantech Open winners get it done quick and cheap

Alphabet Energy took the energy efficiency prize. The startup, which emerged from the Lawrence Berkeley National Laboratory, is making thermoelectric materials that can generate electricity from waste heat. It’s not as sexy as solar but has huge potential to produce power while lowering industrial carbon emissions. “The steel and cement industries generate tremendous amounts of heat that could be used to produce electricity,” said Alphabet chief executive Matthew Scullin. Alphabet intends to disrupt the market not by making super-efficient thermoelectric materials but super-cheap devices that will lower the cost of generating electricity from waste heat. Scullin said the startup needs $2 million to $3 million to commercialize the technology. More>

Want A Job In Akron? Hand Over Your DNA

It's not unusual for employers to conduct criminal background checks during the hiring process. But the University of Akron has taken this to a surprising new level. The Ohio school now reserves the right to require any prospective faculty, staff, or contractor to submit a DNA sample, which genetic-testing experts say makes it the first employer in the nation to take such an extreme and potentially intrusive step. While genetic testing of employees remains exceedingly rare, it has happened. Until 1993, the government-run Lawrence Berkeley Laboratory conducted medical exams with surreptitious blood and urine tests for syphilis, sickle cell anemia, and pregnancy. More>

U.S. energy undersecretary tours Berkeley

Slashing the nation's use of fossil fuels by 2030 will take enormous strides in energy efficiency, and "Berkeley is leading the way" in research on new technology to make that possible, U.S. Undersecretary of Energy Kristina Johnson said in a day-long campus visit Tuesday. She met with Graham Fleming, vice chancellor for research, and Paul Alivisatos, interim director of the Lawrence Berkeley National Laboratory. More>

First Chinese Drywall Test Results Released

Preliminary results from the first round of Chinese drywall tests conducted by the U.S. Consumer Products Safety Commission (CPSC) have revealed that the wallboard emits volatile sulfur compounds at a higher rate, and contains higher levels of sulfur and strontium, than domestically-made drywall samples. Chamber studies conducted by nationally-respected Lawrence Berkeley National Laboratory (LBL) show that Chinese drywall emits volatile sulfur compounds at a higher rate than the U.S. made drywall. More tests and analyses are underway at LBL to determine the specific chemical compounds that are being emitted, the CPSC said. More>

Building Black Holes

Because black holes are so outlandish, it is thought that they make matter behave in ways we don't yet understand and they may therefore hold clues to the answers of some of the toughest problems in physics. If only we could see them. Now scientists are learning to create black holes in their labs, using what are called metamaterials. These are common materials whose structures have been altered so they can make light or sound behave in bizarre ways. In 2008, Xiang Zhang at the University of California at Berkeley used metamaterials to create an invisibility cloak. Instead of reflecting light, the way most things do (which is how we see them) Zhang's materials bend light around an object, rendering it invisible. More>

Dark energy rips cosmos and agencies

A once-favoured space probe to study dark energy is struggling to get off the ground, as three agencies in the United States and Europe tussle over the details of a potential international mission. The rise and fall this year of the Joint Dark Energy Mission (JDEM) — a satellite meant to pin down the repulsive force that is accelerating the Universe's expansion — is partly due to strife between two US agencies, NASA and the Department of Energy (DOE), and a third potential partner, the European Space Agency (ESA). Some, at the Lawrence Berkeley National Laboratory in California, instead proposed a ground-based dark-energy survey called BigBOSS. In presentations in June, the team claimed that BigBOSS would rival JDEM's results for an overall cost of just $85 million. More>

Hyperlens harnesses metamaterials for ultrasound, sonar

Researchers say they have harnessed metamaterials to fabricate the first acoustic hyperlens, potentially offering an eight-fold increase ultrasound and sonar image resolution. Metamaterials have previously been proposed for sonar invisibility cloaks that hide submarines by bending acoustic waves around them. Researchers at the Energy Department's Lawrence Berkeley National Laboratory say they have demonstrated that metamaterials also can be used for acoustic hyperlenses focused with sub-wavelength accuracy.

New Berkeley Lab Report Shows That The Installed Cost Of Solar Photovoltaic Systems In The U.S. Fell In 2008

Researchers at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) released a new study on the installed costs of solar photovoltaic (PV) power systems in the U.S., showing that the average cost of these systems declined by more than 30 percent from 1998 to 2008. Within the last year of this period, costs fell by more than 4 percent. More>

Cutting Carbon Emissions, One Household at a Time

What can the average person really do to combat global warming? Quite a bit, according to a new study. By taking a few well-known, readily available measures, researchers argue, Americans could cut their emissions of the greenhouse gas carbon dioxide by as much as 7% over the next decade. Until now, no study has calculated the total amount of carbon emissions that would be slashed via these measures, the likelihood that people will undertake them, and how many households have already implemented each item, says human ecologist Edward Vine of Lawrence Berkeley National Laboratory in Berkeley, California, who was not involved in the research.

Lawrence Berkeley Lab May Outsource Shuttle Bus Services

Lawrence Berkeley National Laboratory is in negotiations with an outside company to manage and operate its shuttle bus services, a move current unionized bus drivers said is a misdirected effort to cut costs. The move follows years of concerns from the community over the safety and environmental impact of its aging bus fleet, said Jim Krupnick, chief operating officer at the lab. "The need for constant and ongoing improvements ... requires a level of transportation expertise and special management experience beyond what the lab can reasonably provide," said Krupnick in a letter to the community.

UC Berkeley Wants to Turn Former Gold Mine into Lab

The National Science Foundation is giving CAL nearly $30 million to help turn the former Homestake gold mine in South Dakota into the world's deepest laboratory. "We're looking to build a facility to host a variety of different experiments," said Kevin Lesko, a Berkeley Lab researcher and principle investigator for the project. Those experiments that need to be well shielded from sources of background such as cosmic rays or local radiactivity. Physics is just one of the areas of interest for the scientists who hope to set up labs at unprecedented depths. Lesko says geomicrobiologists are trying to understand the organisms that live far below the surface of the earth. More>

Mining Fool's Gold for Solar

Fool's gold, also called pyrite or iron sulfide, can be unearthed just about anywhere, from the hills of California to the villages of Yunnan Province in China. But instead of digging pyrite up, Berkeley Lab researcher Cyrus Wadia is making pure nano­particles of the compound from iron and sulfur salts in his lab. His ultimate goal is to turn fool's gold into real treasure: an inexpensive solar cell. More>

Forklifts from space! Tell your kids

The worst insult you could pay a warehouse manager is that his facility is a black hole. That implies a huge cosmic point of no return. Well if logistics can borrow scientific terminology to imply chaos on a cosmic order, why shouldn’t science be free to use a logistics glossary to bring cosmic theories down to earth? It’s been done. Introducing Sunfall, a kind of outer-space warehouse management system developed for an astrophysics project called the Nearby Supernova Factory. This project represents a new way for scientists at Lawrence Berkeley National Laboratory in Berkeley, CA, to discover and distribute information. More>

Berkeley researchers find new route to nano self-assembly

If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves.

First Acoustic Hyperlens Boosts Power of Ultrasound and Sonar

Imaging an unborn fetus and and spotting a lurking submarine could both become much easier with the world's first acoustic hyperlens. The device manipulates imaging sound waves to provide an eightfold increase in the magnification power of technologies such as ultrasound and sonar. Hyperlenses use specially engineered materials that combine metals and dielectrics, and allow scientists to image features much smaller than typical light wavelengths. Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory applied this approach to capture information in evanescent sound waves, which have higher resolution and more detail but dissipate much more quickly than typical waves.

Frugality rules among Cleantech Open finalists

California regional finalists for the Cleantech Open were announced Wednesday. Think of the Cleantech Open, which started in 2006, as a Western divisions-only March Madness for environmental techies looking for funding. Contestants initially compete against each other in three Western U.S. regions: California, Rocky Mountain, and Pacific Northwest. Since its inception, the contest has garnered more than $125 million in funding for its contestants, according to Cleantech. It's also helped companies like Cool Earth Solar, and GreenVolts get noticed. Alphabet Energy, a team from the Lawrence Berkeley National Laboratory, won the energy efficiency category for a system that produces electricity from waste heat. The group, which twittered a thank you to "the academy" for its win, says its inexpensive method has the potential to offset up to 500 million metric tonnes of carbon dioxide per year. More>

National Lab Shows Costs of Solar Moving Toward Grid Parity

A new report by the Lawrence Berkeley National Laboratory, a research arm of the Department of Energy, or DoE, shows that solar power costs dropped, during the decade 1998 to 2008, from a peak of $10.80 per watt to less than $7.50 per watt, installed. Solar energy’s ultimate aim – to reach grid parity with fossil-fuel generation (coal, oil and gas) – is getting closer, the report notes. What the report doesn’t note, and writers neglect to mention, is the cost of the installation factor as it affects solar parity. More>

Comets Didn't Wipe out Sabertooths, Early Americans?

Though no one disputes the frigid period, more and more researchers have been unable to confirm a 2007 finding that says a collision triggered the change, known as the Younger Dryas. The 2007 research was based on a combination of archaeological artifacts and extraterrestrial magnetic grains in soil samples found in a thin layer of sediment throughout North America. The original team, led by Richard Firestone, a nuclear chemist at Lawrence Berkeley National Laboratory, also found what he said are traces of charcoal and microscopic bits of carbon from intense fires ignited by the collision.

Argonne scientist named top young innovator

Elena Shevchenko spends her days mixing and matching nanoparticles that measure one billionth of a meter. To the average person, research involving such infinitesimal levels can't get much more abstract. But the work Shevchenko is doing at Argonne National Laboratory near Lemont is providing the building blocks for a field with still unforeseen capabilities in medicine, electronics and energy. PAUL ALIVISATOS, [UC BERKELEY PROFESSOR and] interim director of the Berkeley laboratory, in turn had high praise for Shevchenko, who he said is "one of the top scientists worldwide in the synthesis of colloidal nanocrystals and nanocrystal superlattices."

Despite Cuts, Research Keeps UC Berkeley in Public Eye

Professors and researchers from UC Berkeley are constantly in the media spotlight showing off new developments in everything from lasers to invisibility cloaks. But the $6.4 million budget cuts to the campus research office have not only threatened the ability of the campus to be a top educational university, but also its ability to facilitate the research projects integral to the campus's identity. Faculty, combined with a close relationship with the Lawrence Berkeley National Laboratory, supports the campus as a research institution, said Chancellor Robert Birgeneau. More>

The hidden costs of energy production—US$120bn in 2005

A report just released by the National Academies of Science estimates the “hidden” costs of energy production and use. These costs, which include human health effects, physical damages to buildings and other structures, and reduction in grain crop harvests caused by air pollution are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them. Thomas McKone, a senior scientist in Lawrence Berkeley National Laboratory’s Environmental Energy Technologies Division (EETD), and Adjunct Professor in the UC Berkeley School of Public Health, was one of 18 distinguished experts in public health, economics, and energy science who wrote the report.

Subsidies and a glut of panels; in some places, solar's never been cheaper

The government has plowed so much cash into the solar industry that it's effectively pulled the luxury tag off of home solar systems. Combined with local incentives, buyers can save up to 90 percent on a system, whether it's for a single-family home or a 75-unit condo in the city. Solar power has been getting cheaper for years. Panel prices declined 31 percent from 1998 to 2008 because of lower manufacturing and installation costs and state and local subsidies, according to a study released Wednesday by Lawrence Berkeley National Laboratory. But it still took a ramp up in federal incentives this year to bring the cost within many people's reach. More>

Crashing the size barrier

Berkeley Lab, about an hour north of SLAC, has no big linac. But it does have lasers—very, very powerful lasers. Researchers there are working on a complementary technique called laser wakefield acceleration. "Right now, we have three lasers: Godzilla, TREX, and Chihuahua," says project leader Wim Leemans, who heads Berkeley Lab's Laser Optics and Accelerator Systems Integrated Studies program. "Everyone seems to have very macho names for their lasers, so that last one is a bit of a joke." Jokes aside, the lasers are no weaklings. The newest one, TREX, operates at 50 trillion watts for a sliver of a second. For comparison, the average stroke of lightning transfers about one trillion watts of power at its peak. More>

The Great Fume Hood Debate

For decades the assumption was that a safer fume hood was one with high air flow. But air flow is expensive, and vendors and researchers are designing ways to save money while continuing to protect the operator. In 2007, at the behest of Pacific Gas & Electric utility, fume hood experts Dale Sartor of Lawrence Berkeley National Laboratory and Rishabh Kasliwal of Cogent Energy Inc. conducted a study that quantified potential energy savings from revised usage strategies in two different California laboratories that relied on fume hoods.

Driving While Distracted

Defensive driving is helpful if you can give the distracted drivers plenty of space. But in the fray of rush-hour interstates, giving one driver space just puts you closer to another distracted driver. The National Highway Traffic Administration reported that in 2008, 5,870 people died and an estimated 515,000 people were injured in car wrecks that had at least one form of driver distraction noted in the police report. The Lawrence Berkeley National Laboratory in California compiled tips for safe driving, including “do your personal grooming at home,” and “review maps before hitting the road.” And, amazingly: “Keep your eyes on the road.” More>
