Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
Delgado says he doesn't know how many drums of radioactive material are buried within the ship — perhaps a few hundred. But he is doubtful that they pose any health or environmental risk. The barrels were filled with concrete and sealed in the ship's engine and boiler rooms, which were protected by thick walls of steel. The carrier itself was clearly "hot" when it went down and and it was packed full of fresh fission products and other radiological waste at the time it sank. The Independence was scuttled in what is now the Gulf of the Farallones sanctuary, a haven for wildlife, from white sharks to elephant seals and whales. Despite its history as a dumping ground Richard Charter says the radioactive waste is a relic of a dark age before the enviornmental movement took hold. "It's just one of those things that humans rather stupidly did in the past that we can't retroactively fix.""
It's not that we're running out, it's that the best spots for oil now require high tech machinery. This would create a sort of chicken-and-egg problem for a rebuilding society. Technological progress could still happen using other energy production methods. But it would be very slow — we'd never see the dramatic accelerations that marked the industrial age, and then the information age. "A slow-burn progression through the stages of mechanization, supported by a combination of renewable electricity and sustainably grown biomass, might be possible after all. Then again, it might not. We'd better hope we can secure the future of our own civilization, because we might have scuppered the chances of any society to follow in our wake."
Carlsbad's product will sell for around $2,000 per acre-foot (the amount used by two five-person U.S. households per year), which is 80 percent more than the county pays for treated water from outside the area. Water bills already average about $75 a month and the new plant will drive them up by $5 or so to secure a new supply equal to about 7 or 8 percent of the county's water consumption. Critics say the plant will use a huge amount of electricity, increasing the carbon dioxide emissions that cause global warming, which further strains water supplies. And local environmental groups, which fought the plant, fear a substantial impact on sea life. "There is just a lot more that can be done on both the conservation side and the water-recycling side before you get to [desalination]," says Rick Wilson, coastal management coordinator with the environmental group Surfrider Foundation. "We feel, in a lot of cases, that we haven't really explored all of those options."
Speaking at Howard University Medical School, Obama announced commitments from Google, Microsoft and others to help the nation's health system prepare for a warmer, more erratic climate. Google has promised to donate 10 million hours of advanced computing time on new tools, including risk maps and early warnings for things like wildfires and oil flares using the Google Earth Engine platform, the White House said. Google's camera cars that gather photos for its "Street View" function will start measuring methane emissions and natural gas leaks in some cities this year. Microsoft's research arm will develop a prototype for drones that can collect large quantities of mosquitoes, then digitally analyze their genes and pathogens. The goal is to create a system that could provide early warnings about infectious diseases that could break out if climate change worsens.
