Photo project aims for entire coast: "In an unprecedented marriage of high technology and environmental activism, Adelman, a 39-year-old computer programmer from Santa Cruz County [founder of TGV Software], has taken 7,000 aerial photographs of the California coastline -- one roughly every 500 feet. His quest, which could spell trouble for developers building illegal seawalls or blocking public beach access, is to photograph every inch of the state's 1,100-mile shoreline from Oregon to Mexico."  The photos were recently used in a successful Sierra Club suit against a Half Moon Bay resort.  Photos are at www.californiacoastline.org.  12:03:43 PM  permalink  

Upgrading US dams could add 30 Gw: "There are more than 3,500 hydropower units scattered across the United States, which generate about 100,000 megawatts of electricity or 13 percent of the nation's total.  .. The modernization of the hydropower stations has largely been ignored, but can add 20,000 to 30,000 megawatts of renewable generating capacity at existing dams, according data from the U.S. Department of Energy... To mitigate the environmental impacts of hydroelectric facilities, Voith Siemens has developed turbines for Pacific Northwest dams that the company claims nearly double the survival rate of fish that end up going through the dams. In addition, the company has developed an aerating turbine that increases oxygen levels in water downstream from the dam, solving a problem for aquatic life in the Southeast where many hydroelectric facilities use water from the bottom of a reservoir where oxygen levels are low."  11:43:41 AM  permalink
