Dr. Erez Allouche, assistant professor of civil engineering at Louisiana Tech University and associate director of the Trenchless Technology Center, is conducting innovative research on geopolymer concrete and providing ways to use a waste byproduct from coal fired power plants and help curb carbon dioxide emissions.

Inorganic polymer concrete (geopolymer) is an emerging class of cementitious materials that utilize "fly ash", one of the most abundant industrial by-products on earth, as a substitute for Portland cement, the most widely produced man-made material on earth.

While the cost of fuel has put a damper on the travel plans of many Americans, one father-son engineering duo with a passion for RV travel has decided to combat the problem by creating a concept for an electric-hybrid passenger vehicle with the ability to improve fuel economy and increase the acceleration of the motor home towing it.

Dr. Steve Shepard Jr., UA associate professor of mechanical engineering, and his father, Dr. Steve Shepard Sr., a former faculty member and researcher at Mississippi State University, developed the idea for a hybrid dinghy pusher after the cost of fuel curtailed both families’ traveling plans.

Michael B. McElroyA team of environmental scientists from Harvard and Tsinghua University demonstrated the enormous potential for wind-generated electricity in China. Using extensive metrological data and incorporating the Chinese government's energy bidding and financial restrictions for delivering wind power, the researchers estimate that wind alone has the potential to meet the country's electricity demands projected for 2030.

The switch from coal and other fossil fuels to greener wind-based energy could also mitigate CO2 emissions, thereby reducing pollution. The report appeared as a cover story in the September 11th issue of Science.

Annette Von Jouanneby Elizabeth Rusch

She was in the water when the epiphany struck. Of course, Annette von Jouanne was always in the water, swimming in lakes and pools as she was growing up around Seattle, and swimming distance freestyle competitively in high-school and college meets. There's even an exercise pool in her basement, where she and her husband (a former Olympic swimmer for Portugal) and their three kids have spent a great deal of time...swimming.

The National Oceanographic and Atmospheric Administration operation in Muskegon and a Houston-based energy company are partnering to explore alternative energy. 

Mobile Gen LLC has been at the NOAA Great Lakes Environmental Research Laboratory in Muskegon for the past week testing the performance of its new mobile power generation trailer.

Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns. This is the conclusion of two engineers from the University of Oviedo, whose research is being published in the journal Renewable Energy. The method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide.

"One way of making use of low-intensity geothermal energy is to convert mine shafts into geothermal boilers, which could provide heating and hot water for people living nearby", Rafael Rodríguez, from the Oviedo Higher Technical School of Mining Engineering, tells SINC. This type of energy, which is hardly used in Spain, is obtained from the internal heat of the Earth.
