Fukushima scientists brace for riskiest nuclear fuel clean-up yet

"The operation, to remove 400 tons of highly irradiated spent fuel beneath the plant’s damaged Reactor No. 4, could set off a catastrophe greater than any we have ever seen, independent experts warn. An operation of this scale, says plant operator Tokyo Electric Power Company, has never been attempted before. An uncontrolled leak of nuclear fuel could cause more radiation than the March 2011 disaster or the 1986 Chernobyl catastrophe. Here’s what needs to be done: more than 1,300 used fuel rod assemblies, packing radiation 14,000 times the equivalent of the Hiroshima nuclear bomb, need to carefully be removed from their cooling pool."

Scientists emerge after 4 months of space-cooking for simulated Mars mission

"The team lived in a mock-up of a Mars vehicle that was positioned on the side of a Hawaiian volcano, where they experimented with different instant foods and other provisions. For 118 days, Vermeulen and his five team members experimented with a variety of non-perishable ingredients and kept detailed journals of their health, well-being, weight and body mass to determine what foods would be best for a manned Mars mission. NASA recently awarded a $125,000 grant to a researcher who is exploring the possibilities of 3-D printing as a means of producing nutritious, non-perishable foods." Continue reading

Window coating electrically regulates heat and light passing through

"Scientists have created a window coating that can be switched electrically to regulate the amount of heat and light that enters a building. A team of molecular and material scientists from the United States and Spain created a transparent film using nanocrystals — microscopic clusters of atoms that can change the wavelength of light. The window is an electrochemical cell with two glass panes separated by an electrically conductive electrolyte liquid. But several issues must be fixed before the material can be used in windows — including replacing the highly flammable lithium metal used as a counter-electrode, and finding a solid electrolyte."

Solar power to trump shale, helped by US military

"US marines go to war in Afghanistan with solar cells embedded in their rucksacks, efficient enough to recharge lithium-ion batteries for radios and greatly lighten loads. Field patrols will soon have almost weightless solar blankets as well. The US Naval Air Weapons Station already relies on a 14 megawatt array of solar panels in California's Mojave desert for a thrid of its power.The US Navy will derive half its energy supply from renewables by the end of this decade, according to a report. It may be a stretch to say that the US Naval Research Laboratory is the vanguard of the world's green revolution, but not a big stretch." Continue reading

Feds close 600 weather stations amid criticism they’re situated to report warming

"Data from hundreds of weather stations located around the U.S. appear to show the planet is getting warmer, but some critics say it's the government's books that are getting cooked -- thanks to temperature readings from sweltering parking lots, airports and other locations that distort the true state of the climate. The National Oceanic and Atmospheric Administration has closed some 600 out of nearly 9,000 weather stations over the past two years that it has deemed problematic or unnecessary, after a long campaign by one critic highlighting the problem of using unreliable data."

Inside the Hyperloop: the pneumatic travel system faster than the speed of sound

"Mr Musk will not be patenting the design and it will be 'open source'. His motivation for the project came from disillusionment with the Golden State’s high speed rail project, which has been dubbed the 'bullet train to nowhere' after a series of setbacks. He believes the Hyperloop could be built for a tenth of the cost and deliver passengers between the two cities in just 30 minutes, compared to three hours for the bullet train. The bullet train is currently estimated to be costing $68 billion and may not be completed until 2028. It would reach top speeds of only around 130mph. In a survey seven in 10 people said they would 'never or hardly ever' use it anyway." Continue reading

With the Central Subway Project, the Only Way Out is Through

"At times, it's difficult to remember that voters approved the Central Subway. That's because the project, a 1.7-mile extension of the T-line running from SoMa to Chinatown, as described in Proposition K of 2003, hardly resembles its current iteration. A $647 million budget has swelled to some $1.6 billion. An estimated daily ridership exceeding 100,000 is now pegged at 35,100. But if misery loves company, we've got both. A recent U.S. Department of Transportation study of 10 major rail projects revealed an average cost-per-passenger 500 percent higher than the initial figures used to sell the idea." Continue reading

Petition to name San Francisco’s Bay Bridge after Emperor Norton gains support

"Norton, a successful businessman, immigrated to San Francisco from South Africa during the 19th century. After losing his fortune, Norton took the unusual step of proclaiming himself Emperor of the United States in 1859. He later added 'Protector of Mexico' to his official title. Norton is still remembered today because the people of San Francisco embraced him. Newspapers printed his proclamations free of charge and businesses accepted his imperial currency. He strolled through the streets clad in a blue army uniform and a beaver hat, inspecting his royal domain and speaking with his loyal subjects." Continue reading

San Francisco split by Silicon Valley’s wealth

"Heated bidding wars — especially in a half-mile radius of shuttle bus stops — have broken out, causing rents to soar, even double in some cases. Along shuttle routes, trendy new restaurants that serve high-end food and spirits have taken the place of corner stores and mom-and-pop businesses. Anti-Google graffiti has turned up here, and activists recently held a small anti-gentrification rally at which they smashed a Google bus piñata. Ted Gullicksen, executive director of the San Francisco Tenants Union, said he fears that the techies are permanently inheriting the city and won't pack up and leave as they did after the 2000 dot-com crash."

Google to challenge telecoms with fleet of solar-powered balloons

"In recent months, Google Inc has announced plans to bring free wireless Internet access to 7,000 Starbucks cafes across America, eventually displacing AT&T Inc; it has asked U.S. regulators for broader access to wireless airwaves; and it has launched 30 solar-powered balloons over the South Pacific ocean, designed to beam the Internet to remote regions. Then there is Google Fiber, the high-speed cable TV and Internet service that was introduced in Kansas City late last year and that will be expanded soon to Austin and Provo, Utah. Fiber delivers Internet speeds at 1 gigabit per second, as much as 100 times faster than the average U.S. network." Continue reading
