Revival of the electric car: against industry’s gloomy forecast, hybrid & electric cars light up Paris Auto Show
(quote)
Against a backdrop of generally gloomy sales forecasts and belt-tightening, a chorus of optimism rose from automakers at the Paris show as the technical hurdles of hybrids, plug-ins and electric vehicle development -- primarily involving the cost and capacity of advanced-chemistry batteries -- are gradually being overcome. "Two years ago nobody said an electric vehicle was even possible," said Pitt Moos, marketing manager for Smart USA. "Today everybody is saying, 'We're going to make one.' "
At the show, Smart -- the maker of those tiny two-seat city cars -- announced plans to build all-electric vehicles for Europe by the end of the decade. But it hasn't said what its intentions are for the U.S. market. "The challenge has always been the battery," Moos said. Compact, energy-dense lithium chemistry batteries for automotive applications are expensive and can be hazardous. "We have just in the past couple of months become comfortable about a method of making lithium batteries for cars," Moos said. "Now some people are starting to quote Obama: Yes, we can."
Queen Elizabeth II buys world largest wind turbine - towers over Big Ben, to light up thousands of British homes
(quote)
It's been a century or so since Britain ruled the waves, but Queen Elizabeth II will soon reign over the wind. Earlier this year the Crown Estate, which manages royal property worth $14 billion and controls the seas up to 14 miles off the British coast, agreed to purchase - for an undisclosed sum - the world's largest wind turbine.
It's a 7.5-megawatt monster to be built by Clipper Windpower of Carpinteria, Calif. Now the Royal Turbine is getting even bigger: Clipper has revealed to Fortune that Her Majesty's windmill has been super-sized to ten megawatts, producing five times the power generated by typical big turbines currently in commercial operation. The giant's wingspan stretches the length of two soccer fields. At 574 feet, the turbine soars over Big Ben and roughly equals 111 Queen Elizabeths (the actual queen) plus one corgi stacked on top of one another.
World's most exclusive club: Russia, US, now China have technology to allow their astronauts to walk in space
(quote)
China left its mark in space history Saturday, successfully turbocharging its space program into an orbit that could see a Chinese man walk on the moon before the U.S. has a chance to get back there in 2020.
Shenzhou Vll has been successfully orbiting 343 kilometres above Earth every 90 minutes since it blasted off from the Jiuquan launch centre in northwest Gansu province on Thursday night. It was in its 29th orbit when Zhai made his historic walk. China sent its first man into space in 2003. Two more went up in 2005 and the trio this year are on the country's third manned mission.
When Zhai stepped out of the capsule, he confirmed China's membership in the world's most exclusive club: only Russia and the United States have the technology to allow their astronauts to walk in space.

Historical flight - Swiss ‘Rocketman’ Yves Rossy crosses English Channel with homemade jet wing in 10 minutes
(quote)
TO INFINITY and beyond. But first, Kent. Daredevil Swiss pilot Yves Rossy soared into the record books yesterday by making the first solo flight across the English Channel - using a single, homemade rocket-powered wing strapped to his back. Mr Rossy, nicknamed "Fusionman", navigated the crossing from Calais to Dover in less than 15 minutes before proclaiming it was now possible for all of mankind to "fly a little bit like a bird".
Yves Rossy, 49, who calls himself Fusionman - half man, half bird - made the 21-mile, jet-powered flight from Calais, France, to Dover, England, in just less than 15 minutes while traveling at speeds of more than 125 mph, The Daily Telegraph said.
An airline pilot by day, Mr Rossy's attempts to traverse the 22-mile stretch had twice been thwarted by typically overcast British weather conditions. But by yesterday lunchtime, a crisp autumn day allowed the 49-year-old to drop from a light aeroplane 8,000 feet above the French coast and set off into clear blue skies.
Countdown begins for China’s first spacewalk: Shenzhou-7 spaceship launches into orbit with 3 Chinese astronauts
(quote)
After three decades of hoping, 10 years of training, and at least 12 hours preparing his spacesuit, Zhai Zhigang is expected to make history in just 20 minutes tomorrow as the first Chinese astronaut to do a space walk. The 42-year-old former fighter pilot will don a £2m, ten-layered Chinese-designed suit, weighing 120kg (265lb), to exit the Shenzhou VII module.
The Chinese Shenzhou VII spacecraft blasted off at 9:07 p.m. Thursday, carrying three Chinese astronauts into space on this country’s third manned space mission in five years. The Chinese government has spent billions of dollars in recent years building up a space program that it hopes will help China establish a space station by 2020 and eventually will put a man on the moon, accomplishments that would certainly bring the country international prestige.
Large Hadron Collider hibernates after wrong sort of big bang caused by hellion leak, to re-awaken in Spring'09
(quote)
Two weeks ago, the most powerful atom smasher to be built had been switched on to global acclaim and scientists were ready to begin experiments that could unlock many of the enduring mysteries of the Universe. They are going to have to wait a little longer. On Friday the Large Hadron Collider (LHC) created the wrong sort of big bang - a fault so serious that CERN, the European Organization for Nuclear Research, announced last night that the particle accelerator would have to be shut down until next spring for repairs.
Preliminary investigations into the incident, in which a huge quantity of helium leaked from the LHC’s cooling system, have suggested that it was caused by a faulty electrical connection between two of its superconducting magnets. The fault affected a part of the accelerator that is kept chilled to within 1.9C of absolute zero, and it will have to be warmed up to room temperature before the problem can be understood fully and resolved. It will take at least three to four weeks to warm the affected sector and then to open the damaged magnets for inspection, and then another month to re-chill them to their operating temperature. read more »
"Do I really want that CT scan?" Study shows increased radiation exposure, cancer risks, tests often unnecessary
(quote)
CT scans can be better medicine for doctors than for patients - they provide detailed views of internal organs, but the price is increased doses of radiation. A chest CT scan is equivalent to about 100 X-rays.
When Maureen Scanlan had a painful kidney stone episode four years ago, she was pleased that her doctor ordered an annual regimen of CT scans to monitor her condition. The scans involved hundreds of razor-thin X-rays of her innards stitched together by a computer into stunningly detailed 3-D images showing the size and location of the stone, down to the millimeter. What she didn't realize was that the perfection of the images was a result of a radiation dose equivalent to more than a dozen standard abdominal X-rays -- all for a condition that though painful is relatively mundane.
