New Orleans may still be vulnerable to major storm

08/27/10 National Public Radio — Many believe that one of the worst disasters in U.S. history - the flooding of New Orleans - wasn't caused by Hurricane Katrina but by the failure of the flood protection system. Five years later, billions of dollars have been spent to protect the city, but the new flood protection system still leaves New Orleans vulnerable to a major storm. Robert Bea, an engineering professor at UC Berkeley, has spent some 14,000 hours studying New Orleans flood protection since Katrina, and believes that even with the new upgrades, the levees and floodwalls are inadequate, more of a "patchwork quilt" than a true flood protection system.

Innovative project cleaning sewage the natural way

08/16/10 Contra Costa Times — Plants, dirt, birds and fish have all been enlisted to clean Discovery Bay's wastewater as part of an experimental constructed wetland project. Facing $100,000 in fines for copper contamination, the town three years ago partnered with University of California Berkeley scientists to determine whether the latest advancements in artificial wetlands could help clean the town's sewage. The one-of-a-kind project was a success - it reduced copper in the test pond by as much as 90 percent. "In Discovery Bay, they're way ahead of everyone - they're really trendsetters," said Alex Horne, professor of ecological engineering at UC Berkeley and an expert in the field.

$122 million grant to convert sunlight to fuel

07/23/10 San Francisco Chronicle — Scientists from UC Berkeley, Stanford University and the Caltech have been given $122 million to come up with ways to produce fuels directly from sunlight. The U.S. Department of Energy announced the grant Thursday, with the mission to develop practical methods of manufacturing "carbon neutral" fuels similar to the way plants create energy via photosynthesis. "We're not talking about solar panels," said Peidong Yang, a professor of materials science and engineering at UC Berkeley who heads the Bay Area branch of the project. "We are going to develop technology to convert solar energy directly into chemical fuels like methanol, ethanol or just gasoline, through CO2 reduction."

Gulf deep-water drilling should resume on case-by-case basis, expert says

07/22/10 Bloomberg.com — U.S. regulators could end a blanket ban on deep-water oil drilling by increasing oversight of troubled wells and improving safety industrywide, a UC Berkeley engineering professor who studies catastrophes said in an interim report on the sinking of the Deepwater Horizon rig in the Gulf of Mexico. Robert Bea said regulators should determine which drilling operations should be suspended "on a case-by-case basis" as the industry works to improve blowout prevention equipment, inspection procedures and worker training programs.

A well-designed feed-in tariff can drive renewables in California

07/13/10 Greentech Media — A new UC Berkeley study says the state can build renewables rapidly while making big money and adding jobs. A cutting-edge incentive program is the way California can meet its need for renewable energy while bringing enormous financial benefits to the state and adding jobs by the thousands, according to the study conducted by Dan Kammen and Max Wei of UC Berkeley's Renewable and Appropriate Energy Laboratory Energy and Resources Group. A well-designed feed-in tariff will bring California $2 billion in additional tax revenue and $50 billion in new investment, while adding an average of 50,000 new jobs a year for a decade.

Damage control

07/12/10 California Magazine — In 1985, Jack Moehle, Professor of Civil and Environmental Engineering at Berkeley, traveled to Chile to sort through the rubble left in the wake of the devastating 7.8 magnitude earthquake that rocked the coast. He was one of a number of Californian and Chilean engineers who collaborated to study the structural damage. As a result of their research, both the United States and Chile modified their building codes to nearly identical standards. This year, Moehle and a Berkeley reconnaissance team returned to Chile in the aftermath of the 8.8 magnitude shaker on February 27. Because of the similarity in building codes, the sort of damage Moehle has found could predict how California would fare in a major quake.
