greenhouse emissions

Injecting carbon dioxide deep underground into basalt flows holds promise as an abatement strategy. Now, new research by scientists at Washington University in St. Louis sheds light on exactly what happens underground during the process, illustrating precisely how effective the volcanic rock could be in trapping and converting CO2 emissions.

AgarwalA mechanical engineer at Washington University in St. Louis is developing techniques that will lessen our monetary pain at the pump by reducing the drag of vehicles — planes, autos and trucks. Drag is an aerodynamic force that is the result of resistance a body encounters when it moves in a liquid or gaseous medium (such as air). Reduction in drag means less fuel would be required to overcome the fluid resistance encountered by the moving vehicle. Working with undergraduate and graduate students, Ramesh K. Agarwal, Ph.D, the William Palm Professor of Engineering at WUSTL, has successfully demonstrated that the drag of airplane wings and cars/trucks can be reduced by employing the active flow control technology.
