Laurence-Berkeley Lab Director pushing new solutions for Climate change, energy

"...once people stop thinking politically and start thinking from a scientific point of view, surprisingly all the predictions of 'We can't do this' don't seem to come true."

A WARMING WORLD
As warnings grow more dire, Nobelist emerges as leader
The director of Lawrence Berkeley lab is pushing his scientists and industry to develop technologies to reverse climate change

Steve Chu keeps up with all the latest news on climate change, and he knows it's bad.
The Nobel-winning physicist can tell you the projected meltdown rates for the snowpacks of Tibet and the Sierra Nevada. Rivers drying up and millions of people on the move looking for a drink of water? That future, a fantasy just a few years ago, has entered the realm of the possible. But Chu isn't just talking. As head of Lawrence Berkeley National Laboratory, he is focusing all divisions of the most intellectually diverse of the U.S. Energy Department's national labs on a campaign to stand and fight. "These are serious predictions," Chu, 59, said in a recent interview. "It's prudent risk management. It's like saying, 'Your house will burn down in the next 10 years -- 50 percent probability. By the way, do you want fire insurance?' "Chu, who combines a scientific mind thirsting for challenges with an enthusiasm that people find catching, has emerged internationally to champion science as society's best defense against climate catastrophe. "He's using his leadership to challenge their scientists and gear them into addressing this problem in the one last chance we have," said Nate Lewis, a chemistry professor at the California Institute of Technology and an adviser on Chu's energy program. "We don't have that much time."

Chief in Chu's campaign is an unprecedented research pact reached recently between UC Berkeley, oil industry giant BP, the Lawrence Berkeley lab and the University of Illinois. Chu's role in promoting the clout of the closely aligned research programs at the lab and UC Berkeley helped persuade BP to pick the campus for its $500 million biofuels institute. Nearly $400 million in new lab space will expand energy-related molecular work centered at Lawrence Berkeley that involves a cast of partners around the world. And a $160 million Energy Biosciences Institute to be built in three years and funded by BP will include Chu's separate solar energy program. The expansion will put the Lawrence Berkeley lab and UC Berkeley at the center of the world's push for alternative fuels. To Chu, whose heroes include Isaac Newton and Albert Einstein, what's needed now is the will to face the crisis and then to break it down into its component problems.

New energy sources

The first challenge is finding zero-carbon energy sources on a mass scale. Climate change results mainly from there being too much carbon in the atmosphere. Compounding the problem, coal and oil are likely to remain relatively cheap and abundant sources of fuel, especially in the developing world, for decades to come.
Chu is building the lab's capacity to develop zero-carbon energy sources in 10 to 20 years, especially biofuels and a new generation of solar cells.
The profile of lab namesake E.O. Lawrence's enormous particle colliders, which facilitated many breakthroughs in 20th century nuclear physics, has shrunk as the lab morphs into a plant designing and building bioengineered machines from molecule-sized parts. The focus is on the leverage gained when just about every molecule in a system is designed to do work. In the face of relentlessly rising demand, the world needs mass quantities of renewable fuels to keep the situation stable and an almost total conversion to renewables to significantly improve it.
Racing against time, Chu is particularly interested in solar technology. His colleagues at the lab are thinking of farms of photovoltaic cells concentrating sunlight with a coating of nanoparticles, called "solar paint." And they're working on converting solar to liquid fuel by mimicking plant photosynthesis.
Chu started the Helios Project as a framework for his total energy campaign and, not incidentally, a way to market the Lawrence Berkeley lab to private and government funders and to inform outsiders about the lab's work.
Addressing demand, politics
