Diesel fuel prices approaching $5 a gallon — and the resulting economic impact on products transported by truck — have created renewed interest in fuel-saving technologies developed during the past decade at the Georgia Tech Research Institute (GTRI).
Use of pressurized air "active flow control" techniques combined with conventional aerodynamic streamlining could improve fuel efficiency by […]

In recent years, a growing scarcity of energy commodities worldwide has heightened concerns about key geopolitical risks and threats, such as conflict in the Middle East, terrorism and resource nationalism. However, a study released this week by Rice University’s Baker Institute for Public Policy suggests that, taken individually, many of the risks driving the oil […]

High gasoline prices could lead to a dramatic saving in US greenhouse-gas emissions. That’s the conclusion of economists in the US, who suggest high fuel prices are turning consumers off SUVs and onto smaller, more fuel-efficient vehicles.
What’s more, car owners are predicted to cut back on driving in order to save money. Together, these changes […]

Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an adapted trailer. This means that […]

Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr. James Chong at a Science Media Centre press briefing today.
“Methanogens are microbes called archaea that are similar to bacteria. They are responsible for the vast majority of methane produced on earth by living things” says Dr. Chong […]
