UC scientist says ethanol uses more energy than it makes

A lot of fossil fuels go into producing the gas substitute:
"Ethanol, touted as an alternative fuel of the future, may eat up far more energy during its creation than it winds up giving back, according to research by a UC Berkeley scientist that raises questions about the nation's move toward its widespread use.

A clean-burning fuel produced from renewable crops like corn and sugarcane, ethanol has long been a cornerstone of some national lawmakers' efforts to clear the air and curb dependence on foreign oil. California residents use close to a billion gallons of the alcohol-based fuel per year.

But in a recent issue of the journal Critical Reviews in Plant Sciences, UC Berkeley geoengineering professor Tad Patzek argued that up to six times more energy is used to make ethanol than the finished fuel actually contains.

The fossil energy expended during production alone, he concluded, easily outweighs the consumable energy in the end product. As a result, Patzek believes that those who think using the 'green' fuel will reduce fossil fuel consumption are deluding themselves -- and the federal government's practice of subsidizing ethanol by offering tax exemptions to oil refiners who buy it is a waste of money."

Digital Cam media safe to fly with

Technocrat.net : "Recent tests found no evidence of X-ray scanner damage to digital camera media cards or to the images they hold. The tests of scanner models currently in use in the U.S. transportation industry were jointly conducted by the International Imaging Industry Association (I3A), the leading global association for the imaging industry; SanDisk Corporation, a manufacturer of digital media cards; and the U.S. Transportation Security Administration (TSA). These findings mean that digital cameras and their image storage media can travel safely in either checked or carry-on bags, which will be reassuring to holiday travelers. And though they were not explicitly tested, it is likely that images on camera-phones will be safe in either situation as well. More care is needed for cameras with film, however, as the X-ray scanners for both checked and carry-on luggage can fog both developed and undeveloped film."

Artist turns animals into everyday objects

Ananova - A Chilean artist is making a name for herself with an exhibition in which stuffed animals are transformed into household objects. Artworks on display include a chick turned into a lamp, and 'sheep bag' - a lamb carcass fitted with handles. Artist Caterina Purdy says her exhibition at the Experimental Arts Centre in Santiago is intended to be humorous but also makes a serious point. She told Las Ultimas Noticias online: 'It is possible to see my work as something scary, but I find it beautiful. 'There is also irony and humour in my objects as well as a criticism of the way animals are treated by society.'"

BW Online | March 1, 2004 | Software : "As Stephen and Deepa emerge this summer from graduate school -- one in Pittsburgh, the other in Bombay -- they'll find that their decisions of a half-decade ago placed their dreams on a collision course. The Internet links that were being pieced together at the turn of the century now provide broadband connections between multinational companies and brainy programmers the world over. For Deepa and tens of thousands of other Indian students, the globalization of technology offers the promise of power and riches in a blossoming local tech industry. But for Stephen and his classmates in the U.S., the sudden need to compete with workers across the world ushers in an era of uncertainty. Will good jobs be waiting for them when they graduate? 'I might have been better served getting an MBA,' Stephen says."
