Israeli researchers at Tel Aviv University have developed a device which is likely to save the U.S. trucking industry some $400 million per year. The drag reduction device, an actuator, was exhibited at the “World’s Best Technologies Showcase” in Texas.

Through the combined action of suction and pulsed blowing of airflow, the device reduces drag in a controlled manner when it is attached to the back of the truck or trailer.

Professor Avraham Seifert and his colleagues at the Iby and Aladar Fleischman Faculty of Engineering say the device is projected to increase fuel economy in trucks and trailers by as much as ten percent.
