Poop-to-power projects pumped up

Publication:   Date: November 9, 2011   View Article

Innovators from around the world who see power in steaming piles of poop are getting serious money from Microsoft billionaire Bill Gates’ foundation to help the world’s 2.1 billion urban dwellers without access to sewers live safer, more sanitary and electrified lives.

Grantee Daniel Yeh, a civil and environmental engineer at the University of South Florida, for example, will use the funds to field test an advanced technology that harvests nutrients, energy, and water from wastewater.

After 9/11, safer skyscrapers rise

Publication:   Date: September 6, 2011   View Article

Ten years after terrorists slammed a pair of fuel-laden jetliners into the iconic twin towers in lower Manhattan, engineers around the world are designing stronger skyscrapers to resist the worst that nature and evil minds can throw at them.

A prime example is 1 World Trade Center under construction at Ground Zero itself.

The sky-piercing, 1,776-foot-tall spire takes into account everything investigators learned from the collapse of the World Trade Center’s twin towers on Sept. 11, 2001, making it “an outstanding building for terrorist resistance,” said Gene Corley, a lead investigator of the federal study and a vice president at engineering firm CTL Group.

8.7 ideas in earthquake prediction

Publication:   Date: April 6, 2009   View Article

Earthquakes are notoriously difficult, if not impossible, to predict. “You are dealing with a very complex physical system that behaves very differently in many places,” says David Schwartz, a geologist with the U.S. Geological Survey’s San Francisco Bay Area Earthquake Hazards Project. Nevertheless, researchers are trying to improve earthquake probability forecasts and working toward, maybe one day, prediction and prevention. Learn about eight of their ideas.

Wouldn’t it be nice if airline pilots turned on the “fasten seat belt” sign before the person standing in the aisle toppled onto your lap because of turbulence?

NASA researchers are on the job. They are developing a pair of technologies that will give pilots several minutes’ warning so they can steer clear of the erratic, gusty winds.

New Icing Warning System for U.S. Airplanes Debuts

Publication: National Geographic News   Date: December 6, 2006   View Article

Beginning today pilots will have more reliable information about the threat of dangerous icing conditions as they fly across the continental U.S.

The information could save the airline industry more than $20 million a year in aircraft damage and fuel by guiding pilots away from areas in the atmosphere where icing can take place, according the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
