Building green performance motorcycles

04/17/12 — Electric motorcycles are quiet, and from a power perspective more efficient. Both traits are not lost on the rider. “If you get on these electric motorcycles the first thing you notice is a magic carpet ride feel,” says Abe Askenazi, B.S'92, M.S'94 ME. “It's almost like flying. It feels like you are on a glider and this thing is propelling you forward. You don't hear all of the drama of power production, you are just doing it.” Askenazi has traveled a long road to become the chief technology officer at Zero Motorcycles, one of the nation's leading electric motorcycle manufacturers.

Smart sensors in the woods

03/19/12 — About 60 percent of the water used in California comes from Sierra Nevada snowmelt. Monthly measurements help water managers estimate the amount of water held in the snowpack and allow them to allocate the state's most precious resource. Now, the Sierra Nevada is going high tech. Wireless sensors developed by Steven Glaser, professor of civil and environmental engineering, are being tested in an ambitious pilot project at the UC Merced Sierra Nevada Research Institute.

When the car is the driver

02/17/12 National Public Radio — This week the state of Nevada finalized new rules that will make it possible for robotic self-driving cars to receive their own special driving permits. Do people notice a self-driving car and gawk? "We get a lot of thumbs up," says Berkeley Engineering alum Anthony Levandowski (M.S.'03 IEOR), one of the leaders of Google's self-driving car project. Google's fleet of robotic cars has driven more than 200,000 miles over highways and city streets in California and Nevada.

The $3.5 million prize recognizes and rewards innovation, leadership and longterm vision in renewable energy and sustainability. Gadgil was recognized for "his sustainable humanitarian work in Darfur -- providing energy efficient cooking stoves known as Berkeley-Darfur stoves, cutting the need for firewood by 55 percent."

Diesel truck emissions in Oakland fall sharply

01/17/12 Institute of Transportation Studies — Recent field studies conducted by UC Berkeley civil and environmental engineering professor Robert Harley and his research team show that emissions of unhealthy pollutants from diesel trucks in West Oakland have been reduced by half in a matter of months, as a result of state regulations that banned the oldest, dirtiest trucks and set deadlines for retrofitting middle-aged trucks with diesel particle filters.

Paving the way

10/17/11 — Often it's only an unexpected pothole or a bumpy road that draws our attention to pavement conditions. But for civil and environmental engineering professor Carl Monismith (B.S'50, M.S'54 CE), the ups-and-downs of pavement have been worth his ongoing consideration for the past 60 years. As the co-director of the Pavement Research Center (PRC), Monismith has been studying pavement design and technology since 1951.

Tapping the West’s water

09/12/11 — Two years ago David Sedlak, UC Berkeley professor of civil and environmental engineering, was invited to speak at the Nobel Conference in Minnesota about his area of expertise: urban water systems. Seeing an opportunity to tell the story of the water delivery networks that are falling apart under our feet, Sedlak did more than deliver a talk describing the problem. He came up with an idea to help solve it.

In vino veritas

09/12/11 — As any wine-sipping oenophile knows, the quality of a wine is influenced, among other things, by the geography, geology and climate of the specific vineyard in which the grapes are grown. The French even have a word for it - terroir - which can be loosely translated as “a sense of place.” For Berkeley Engineering alum Jason Mikami, whose boutique winery produces a handcrafted Zinfandel wine using grapes from his family's estate, the terroir of the vineyard is not only evident in his wines, but also in his own journey as a winemaker.

Tough act to follow

08/18/11 — MIT rejected him. CalTech rejected him. So did Duke and UCLA. But Berkeley saw potential in the teenager from a small Catholic high school in Modesto, and from the time he arrived on campus, Matthew Zahr didn't disappoint. The civil and environmental engineering student graduated this spring with a 3.988, earning his major's top undergraduate award, the department citation, and was nominated, along with four others, for Berkeley's highest undergraduate honor, the University Medal.

Environmental engineering professor Kara Nelson receives grant for sanitation research

05/02/11 The Daily Californian — UC Berkeley professor of environmental engineering Kara Nelson has been awarded a five-year $100,000 grant from the Bill and Melinda Gates Foundation for her unconventional research in sanitation and human waste management. Nelson said she will use the grant money to treat human waste at the point where it is being produced, in an effort to eliminate the amount of contact humans have with fecal pathogens.

PEER presents briefing on Japan earthquake and tsunami

04/27/11 Pacific Earthquake Engineering Research Center — The Pacific Earthquake Engineering Research Center will give a public briefing presenting the preliminary results of a U.S. research team's reconnaissance trip to Japan to survey damage from the 9.0 magnitude Tohoku earthquake and ensuing tsunami of March 11, 2011. The briefing, to be held on April 28, is jointly organized by the PEER, GEER, and EERI's Learning from Earthquakes Program.

Radioactive particles arriving in the Bay Area, but pose no risk, say UC scientists and health officials

03/18/11 San Jose Mercury News — While public health officials downplayed fears that a plume from Japan's crippled nuclear reactors was descending on California, scientists at UC Berkeley declared they were already detecting radioactive particles from 5,000 miles across the ocean. The differing accounts illustrated the confusion on the fallout from Japan's crisis, but scientists and public health experts agreed that whatever radiation may drift to California and the West Coast will be too minuscule to pose any health risks. "We see evidence of fission particles -- iodine, cesium, barium and krypton, a whole dog's breakfast of radiation," said Ed Morse, professor of nuclear engineering at UC Berkeley, whose students have set up a monitor on the rooftop of the campus's Etcheverry Building.

Gulf of Mexico oil spill response should be focused, Berkeley engineering professor says

03/16/11 NOLA — The latest detailed analysis of the BP oil disaster in the Gulf of Mexico offers no new theories on what caused the deepwater-well blowout in April, but it does bring a fresh take on how the oil industry and government can make drilling safer. Bob Bea, the UC Berkeley engineering professor who achieved renown for his independent analysis of the levee failures after Hurricane Katrina, says top oil companies need to put their heads together to develop best practices and equipment for drilling in the most dangerous conditions.

How to measure an oil spill

02/02/11 — When oil was flowing from BP's broken well at the bottom of the Gulf of Mexico last spring, the company estimated the flow rate at about 1,000 barrels a day. But news outlets wanted an independent estimate. Could Ömer Savaş, an expert in fluid mechanics and turbulent flows, help? Soon Savaş became involved in a national effort to establish the “official” flow rate, a number that would dictate not only the level of resources assigned to the cleanup but also its legal ramifications once the emergency had passed.

Chlorine substitutes in water may have risks

01/07/11 National Public Radio — Water systems across the country are changing the way they disinfect drinking water because the traditional disinfectant, chlorine, can leave behind toxic chemicals. But alternatives to chlorine are turning out to have risks of their own, says UC Berkeley professor of civil and environmental engineering David Sedlak, who wrote an analysis in the journal Science.

Energizing the energy agenda

12/14/10 — While climate change and carbon emissions are very much in today's headlines, what is less often discussed is the need to provide technological societies with the economic imperative to make changes in our global energy system.

Wheels of change in South Africa

12/14/10 — More than 9 million South African children walk to school every day. Three million walk for more than an hour, and in the rural countryside, some walk more than four hours. “It's madness,” says Louis de Waal (M.S'72 CEE), who grew up in rural South Africa and spent his professional life designing and building thousands of kilometers of roads there, many of which opened up inaccessible places deep in the country's interior. Now retired, De Waal is on a mission to improve mobility for all South Africans, especially in rural areas. The goal, says the 73-year-old Cape Town resident, is to keep children in school and help adults reach work more easily, ultimately easing poverty and slowing the flood of people forced to move to urban areas for work.
