Here's a review of a new book, Deep Water: The Epic Struggle Over Dams, Displaced People, and the Environment from AlterNet. They write, "We forget now that the American environmental movement was born not in reaction to smog or to dirty water, but to dams. That John Muir, the great conservationist of the first half of the twentieth century, founded the Sierra Club to fight the dam at Yosemite's Hetch Hetchy, and that David Brower, Muir's successor, built the club into the prototype of modern activism in the struggles over dams at Dinosaur National Monument, Glen Canyon, and the Grand Canyon. We forget because our big-dam days are over -- almost everything that could be plugged with concrete long since has been. But the rest of the world is still deep in these fights. In fact, in many places they still define both environmentalism and development, as journalist Jacques Leslie's superb account."

Interior Secretary Dirk Kempthorne has signed off on the Platte River Cooperative Agreement, according to the Rocky Mountain News. They write, "Kempthorne's approval sets in motion a program 'to pool resources and expertise' across the river basin to restore wildlife habitat while preserving the water needs of farmers, according to Mark Limbaugh, the Interior Department's assistant secretary for water and science. 'This agreement has been several years in the making, and represents a tremendous amount of collaboration by many who are concerned about the future of the species and the future of water projects,' Limbaugh said. The stretch of the Platte River in central Nebraska, near Kearney, is home to a vast array of wildlife, including migrating whooping cranes. Threatened and endangered species, such as the piping plover, least tern and pallid sturgeon, also depend on the region's complex river ecosystem. Flows in that stretch of the river have fallen sharply over the past several decades, in part because of heavy urban and agricultural use in Colorado, Nebraska and Wyoming. Spring flows that once poured through the area are now trapped in high-elevation Colorado reservoirs. Thus, rare species of wildlife have come under the protection of federal law, which requires the states to take steps to improve habitat."

The Colorado School of Mines is in the hunt for economically viable solution for producing hydrogen from coal, according to the Fuel Cell Works. They write, "The Department of Energy today announced the selection of six research and development projects that will promote the production of hydrogen from coal at large-scale facilities. This central approach will combat climate change by allowing for the capture - and subsequent sequestration - of carbbon dioxide generated during hydrogen production. The selections support President Bush's Hydrogen Fuel Initiative, which provides funding for research and technology development to realize a future hydrogen economy that minimizes America's dependence on foreign oil and reduces greenhouse gas emissions. Pure hydrogen is a potential energy carrier for the future, and it may be produced from hydrogen-containing materials such as water and fossil fuels. Until other resources are available to produce hydrogen at lower costs, production from coal is the most economical source.
"The large-scale production of hydrogen from coal faces several technological challenges that must be overcome before its widespread use becomes a reality. To address these challenges, the new cost-shared projects will focus on two areas of interest:
"* Ultra-Pure Hydrogen - Hydrogen has the potential to be used in a number of end-use applications, each having its own purity standard. Some of these end uses include hydrogen turbines, fuel cells, and modified internal combustion engines. Three projects will focus on the development and scale-up of advanced materials and devices for producing ultra-pure hydrogen from coal-derived synthesis gas.
"* Process Consolidation - Strategies are needed for selectively removing pure hydrogen, carbon dioxide, and synthesis gas impurities in a single-reactor configuration that can operate simultaneously at high temperature and high conversion. Three projects will perform a combination of theoretical and experimental research to provide a scientific basis for consolidating multiple processes - synthesis gas cleanup, water-gas shiftt reaction, hydrogen separation, and carbon dioxide separation - into a single module."
