Corbett, a professor of marine policy in UD's College of Earth, Ocean, and Environment, works on energy and environmental solutions for transportation. He has launched a website that reports the impact of the Deepwater Horizon oil spill in terms of lost uses of the lost fuel on a daily basis.
Visitors to the website can choose the spill rate they believe is most accurate from a range of reported estimates, and the website will automatically calculate how many cars, trucks, and ships could have been powered for a year, based on Bureau of Transportation Statistics.
Here are just a few of Corbett's findings:
* By May 31 (41 days after the spill), the lost energy could have fueled one freight truck on 17 trips across all 4 million miles of U.S. highway.
Corbett says he developed the website to help put the oil spill in a perspective to which everyday users of petroleum, including most Americans, can relate.
Transportation activities consume about two-thirds of all petroleum in the United States -- more than 20 billion barrels per day, according to Corbett. Gasoline for automobiles accounts for about two-thirds of U.S. total transportation energy, diesel fuels power most of our goods movement, and most international containerized cargoes are delivered by ships -- the largest vehicles ever built.
“Energy resources offshore are being explored because each of us petroleum consumers is demanding more,” Corbett says.
The website also may help us decide how to reduce risks of future oil spills.
“Drilling this exploratory well by the Deepwater Horizon was an extremely high-risk proposition,” Corbett says. “At $75 per barrel of crude oil, the oil spilled would have been worth about $90 million in terms of spill oil value if extracted for refining. Some experts are now estimating damages from the spill to exceed $10 billion. That's a potential 100 to 1 loss, given the spill damage-to-value ratio.”
Corbett's research collaborations focus on ways to improve the energy performance of transportation systems using ships, trucks, trains, and other vehicles. There are ways to reduce the need for offshore oil drilling, Corbett says:
* If we improve automobile fuel economy to 35.5 miles per gallon (mpg), as proposed by the current administration, we would offset demand equivalent to the gasoline energy lost by 199 years of Deepwater Horizon daily releases.
* If we add only 2 mpg to the fuel economy for trucks, as proposed by the Union of Concerned Scientists, we would offset diesel-driven energy demand equivalent to 12 years of Deepwater Horizon daily releases.
* Rebalancing how we transport goods would achieve substantial energy savings. A shift from truck to rail for specific commodities/routes would require about 20 percent of the energy per ton-mile compared to trucking. Achieving this would require an investment in infrastructure and green logistics to facilitate intermodal combinations of trucking and rail rather than treating the modes as competitors.
* Shifting passengers from single-occupant cars to car-sharing/carpooling and better transit also would produce important reductions.
“The wise use of petroleum and other energy resources is an opportunity for each of us,” Corbett says. “We can reduce the need to drill deeper into environmental risk. Within a few miles of our communities, we can do a lot to reduce energy demand.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
