Is ocean desalination a good idea for California?

By Alison Hawkes

Is ocean-water desalination a good way to solve California’s impending water crisis? Conservationists are pushing back on the idea, saying that technology is harmful to the environment because it can entrap wildlife and create byproducts heavily concentrated with salt and chemicals that would be dumped back into the ocean. Desalination also uses a lot of power. They favor conserving water at the tap. There are now nearly a dozen plans for desal plants in California, including in Marin. [DC Bureau]

Adam Werbach on Libya, $200 oil, and clean energy

Controversial environmentalist Adam Werbach says that Libyan civil unrest could push oil prices up to $200 a barrel, and that’s a good thing for the adoption of clean energy. Unlike the last time the Americans faced high oil prices (2008), today the U.S. is better positioned to seize green technology research funding, drive electric cars, and build a clean energy infrastructure.

San Bruno gas pipeline had multiple poorly welded seams

Federal investigations into the PG&E San Bruno gas pipeline explosion found that multiple welded seams were “grotesquely at odds with industry standards and specifications.” PG&E declined to comment on the finding, but yesterday agreed to send notices to customers who live within 2,000 feet of a gas-transmission line. The National Transportation Safety Board hearings also revealed that in the 90s PG&E replaced miles of pipeline in San Bruno, stopping 300 yards short of the explosion site.

Recent cold weather may damage locally-grown fruit and raise prices

Just as many Central Valley fruit trees began to bloom, temperatures dropped last week, potentially harming many fruit and nut trees at a particularly vulnerable time. In particular stone fruit, such as peaches, apricots, and plums are susceptible to frost. But farmers won’t know the extent of the damage until harvest time. Buyers will find out when they look at the prices. [Marin Independent Journal]

Earth headed toward sixth mass extinction say Berkeley scientists

If the current rate of extinction continues, Earth will lose some 75 percent of its species in three centuries, according to a new study by U.C. Berkeley scientists published in the journal Nature this week. Mass extinctions, such as the one predicted, have only occurred five times in the Earth’s history. The dinosaur die-off is the best known. [San Jose Mercury News]

San Mateo cities try to regroup behind high-speed rail

Cities in San Mateo County that want high-speed rail on the Peninsula are banding together, saying they have more sway as a group. Congressional representatives told city leaders their constant bickering has made them “the laughingstock of Washington D.C.” and that receiving federal money requires cooperation. But signs don’t look good. Many of the cities in the new San Mateo County Rail Corridor Partnership disagree about how rail plans should proceed. [San Jose Mercury News]

Rain wasn’t the only thing falling into the Bay yesterday. Some of the 10,000 red balloons released in San Francisco as part of a publicity stunt by a video game company began dropping into the Bay to the disbelief of environmentalists. The company, THQ, said the balloons were meant to simulate part of its warfare game. The EPA, Coast Guard, and city of San Francisco are investigating the incident.

Demos of SF’s bike sharing program

12/20/2010

By Alison Hawkes

San Francisco is pioneering a new bike-sharing program in the vein of Paris and Barcelona. The project has been trumpeted by Mayor Gavin Newsom’s office for years. With a $4 million grant that eventually came through, the city is readying 500 bikes for deployment in the spring of 2012.

That’s a bit of a ways off. But bicycling companies vying for the city contract were out demo-ing their systems this past weekend. Explaining how it will all work was Jerold Chinn at Shareable who also created this video of B-cycle .
