A greenhouse gas 17000 times more potent than CO2: NF3 gas used in making flat panel TVs, computer displays, microcircuits
(quote)
A gas used in manufacture of flat panel televisions, computer displays, microcircuits, and thin-film solar panels is 17,000 times more potent a greenhouse gas than carbon dioxide, and it is four times more prevalent in the atmosphere than previously estimated, according to a study released Thursday. Researchers using a new NASA-funded measurement network discovered there was 4,200 metric tons of the gas nitrogen trifluoride in the atmosphere in 2006, not 1,200 tons as previously estimated for that year.
In 2008 there are 5,400 metric tons of the gas in the atmosphere, an average of an 11 percent tonnage increase per year, said Ray Weiss, head of the research team from the Scripps Institution of Oceanography in La Jolla, California. Nitrogen trifluoride, which could not be detected in the atmosphere using previous techniques, is 17,000 times more potent as a global warming agent than a similar mass of CO2. The rate of increase means that about 16 percent of the amount of the gas produced globally is being emitted into the atmosphere, the researchers estimate.
Faster than a speeding bullet - world's first 1000-mph supersonic car "Bloodhound" to be built by British engineers
(quote)
British engineers have unveiled plans for the world's first 1,000-mph car, a muscular streak of gunmetal and orange designed not to break the world land speed record but to shatter it. Bloodhound SSC, named after the British cold war supersonic air defence missiles, will attempt to beat the existing record by more than 250mph.
The £12m car is to be announced today by Lord Drayson, the science minister. Working from an aircraft hangar in Bristol, the team's engineers have been working on the project in secret for the past 18 months. Calculations suggest the car could reach 1,050mph, fast enough to outrun a bullet from a .357 Magnum revolver. The car was proposed by Drayson, a racing car enthusiast, as a project to inspire a new generation of scientists and engineers, who are in desperately short supply in UK. The Bloodhound team plans to have the car built within a year, with the record attempt expected in three years.
Genius. Recycled silicon wafer factory, flipped switch on US' largest solar cell plant: German SolarWorld AG
(quote)
A solar cell factory has sprouted in Oregon’s Silicon Forest amid the region’s old-growth semiconductor plants. Bonn-based SolarWorld AG officially flipped the switch on the United States’ largest solar cell plant. (See the Fortune video here.) The company, the world’s fifth largest solar cell manufacturer, has recycled a former Komatsu factory built to produce silicon wafers for the chip industry. The new plant is expected to reach a capacity of 500 megawatts (MW) and employ 1,000 people by 2011. The solar industry is expected to grow to $74 billion in 2017 from $20 billion in 2007, according to Clean Edge Inc., a market research firm focused on clean technology.
Men go back to the mountains as they go back to sailing ships at sea, because in the mountains and on the sea they must face up.

Inventors in 800mi car race run on wood chips, cow dung, veg oil, no gas! Jagged Sierra Nevada, bleak flatness of Death Valley
(quote)
Wayne Keith, a hay farmer from Springville, Ala. (population 3,000), pulled into Berkeley last week driving a lime-green pickup truck that runs mostly on wood chips but sometimes cow dung, too. Keith, who wore dirt-flecked overalls and a trucker's cap, was in town to compete in the first Escape from Berkeley race, a kind of mini Cannonball Run to Las Vegas for drivers of vehicles that run on anything but petroleum. Two other racers relied on vegetable oil, one on alcohol and one on steam power to run his carriage (mostly for show; after a few miles, it was put on a trailer to traverse some of the dicier terrain).
Techies' new frontiers: Portland OR, Bethlehem PA, Blacksburg VA, Bellevue WA, Boise ID, Folsom CA
(quote)
Portland, Oregon
Some people call it Silicon Forest. That's because the Portland metropolitan area has done an impressive job of attracting entrepreneurial tech talent, thanks in part to the presence of Tektronix, IBM and Intel. In fact, many of the city's computer-technology companies were started by former employees of these tech giants, focusing on areas such as open-source and educational software. But Portland isn't just about computer technology. Over the years, the city has earned a reputation for progressive energy policies, attracting a large sustainable-technology community, as well as the U.S. headquarters of Vestas, the world's largest wind-turbine manufacturer. Support for the Portland tech scene comes from organizations such as Oregon InC, a state-funded venture dedicated to nurturing Oregon's innovation economy.
Bethlehem, Pennsylvania
With the decline of its steel industry over the past two decades, Bethlehem has worked hard to encourage its burgeoning local tech community. Numerous startups have sprouted in recent years, thanks in part to the city's two hospitals and two local colleges. New technologies currently in development range from computer chips to instruments used in truck-tire manufacturing. Ben Franklin Technology Partners, a state-funded program based in Lehigh University, works with early-stage tech firms across 19 counties, awarding grants and helping companies find everything from funding to skilled workers and technology. The city also provides support, working with local groups to offer low-interest loans and enterprise-zone incentives. read more »
Monks and nuns become hoteliers in economically challenging times: monastic doors open for travelers in Europe
(quote)
When Kathleen Mazzocco was researching places for an affordable family vacation in Italy back in 2002, booking a room in a convent was “like shooting in the dark.” The guidebook to religious lodgings that Ms. Mazzocco used had no photographs, and she wasn’t sure the information was up-to-date. But by the time Ms. Mazzocco, a public relations consultant from Lake Oswego, Ore., returned to Italy last year, making a reservation at a monastery was not so different from booking a regular hotel. She found the cliffside Monastero S. Croce, in Liguria, on the Internet, viewed photos of it on the monastery’s own Web site, sent an e-mail message asking about availability, heard back promptly, and, at the end of her stay, paid with a credit card. “They’d entered the modern age,” she said.
For centuries Europe’s convents and monasteries have quietly provided inexpensive lodging to itinerants and in-the-know travelers, but now they’re increasingly throwing open their iron-bound doors to overnight visitors. They’ve begun Web sites - many with English translations and detailed information about sampling monastic life for a night - and signed on with Internet booking services. Some have even added spa offerings. Occupancy has shot up at many places, and some of the more centrally located are often fully booked. read more »
