Global-warming lecture offered free at UH-Manoa Advertiser Staff Richard Alley, described as one of the world's leading climate researchers, will talk about global warming and other issues during a lecture Tuesday night at the University of Hawai'i-Manoa Campus Center Ballroom. The event, which is free and open to the public, will begin at 7 p.m. Alley's presentation is part of the UH-Manoa Distinguished Lecture Series centennial year program. Alley, the Evan Pugh Professor of Geosciences at Penn St. University, has spent numerous field seasons in both Antarctica and Greenland studying the waxing and waning of ice sheets. His lecture presentation is titled, "Get Rich and Save the World: Global Warming, Peak Oil, and Our Future." Alley has chaired a National Research Council study on Abrupt Climate Change, and serves, or has served, on other advisory panels and steering committees related to climate change. In addition to publishing numerous scholarly articles on climate change and Earth's recent climate history, Alley's popular book 'The Two-Mile Time Machine: Ice Cores, Abrupt Climate Change, and Our Future' (Princeton University Press) provides a firsthand account of his work drilling the Greenland ice sheet, and places the results of his own work in the context of global climate change research. The book received the 2001 Phi Beta Kappa Book Award in Science. In addition to being recognized as an exceptional scholar, he is well known as a source of accessible public information about climate change. He has been featured on TV (Nova, BBC), radio (NPR, Earth and Sky), and print outlets (New York Times, Time Magazine). Alley will also lead a seminar — also open to the public at no charge — on the topic, "Fraying at the Edges — Sea Level and the Bizarre Behavior of Ice Sheets," from 3 to 5 p.m. Thursday in the Architecture Auditorium on the Manoa campus. the.honoluluadvertiser.com

I have 900 miles a day grazing next door. Cow Manure Could Be Cheap Alternative to Gas A Cow Can Power a Car for 15 Miles a Day May 29, 2006 — The secret to cheaper gas could lie in cow dung. The Vehicle Research Institute of Western Washington University in Bellingham, Wash., has been turning cow manure into fuel that can power a natural-gas car. Researchers are not shoveling manure straight into the gas tank but pumping the methane — a gas created by the manure — into the car. They have some hard-working cows at a dairy farm in Lyndon, Wash., to thank for this experiment, which could mean cheaper car fuel for many people. "We are talking about dairy cows," said Eric Leonhardt, an engineering technology professor and director of the Vehicle Research Institute. "So they are very well-trained. They go in one spot. They feed and do their business in one location. And then that material is pumped into a holding tank." For 21 days, the manure sits in an underground tank and stews. Then, using regular old garden hoses, researchers siphon floating methane out of the holding tank. They must purify the methane to remove other gases before pumping it into the car. Every cow can produce enough manure in a day to make a car go about 15 miles. If you take 20 cows, you get 300 miles of gas in your car. There are not enough cows in the United States to power every vehicle. But Vehicle Research Institute researchers say a natural-car powered by methane could be a great solution for certain rural communities. The price of cow fuel will put some consumers, well, over the moon. "The gas is currently being sold at one-fifth the pump price," Leonhardt said. abcnews.go.com Tapping the Latent Power in What's Left Around the Barnyard Claudia H. Deutsch, NY Times In a sense, it is the ultimate renewable source of fuel. Weather anomalies can kill off corn crops, calm the winds, obscure the sun — but through rain or shine, gusts or stillness, cows and hogs and turkeys spew forth a steady stream of MANURE, one of nature's richest sources of METHANE, a principal component of natural gas.
