The new X-Flex Blast Protection wallpaper, created Berry Plastics and the U.S. Army Corps of Engineers, promises to help walls keep their shape and guard against flying debris in the face of explosions. Watch as a heavy wrecking ball fails to tear down a brick wall lined with a single sheet of this amazing stuff. [PopSci]
Coal-fired power plants are a major source of carbon dioxide, a greenhouse gas. But they continue to be built because coal remains an abundant and cheap fuel source. Still, a report from the Massachusetts Institute of Technology says that carbon dioxide emissions could be drastically cut, even with increased coal burning. The trick: Future power plants would have to capture the carbon and then sequester, or bury, it underground.
Our Earth is a treasure trove of valuable, underground resources, and mining engineers help to locate them. They and petroleum engineers also design techniques and equipment that ensure that minerals, oil and gas are extracted as safely and cleanly as possible. Moreover, some petroleum engineers also work on developing alternative energy sources.
Coming into Virginia Tech’s engineering program, Angela Walker knew that as a woman, she would be in the minority. That’s why she chose to live in Hypatia, an all-female engineering community, her first two years. “Nothing can replace the ability to walk down the hallway and get help on homework,” says Walker, now a junior majoring in mechanical engineering. “If it weren’t for the network of people you meet through this program, many girls might feel intimidated to the point that they decide to drop out of engineering,” she says. “We empower each other.”
