An Israeli firm called R-Jet Engineering has designed a new jet engine that could lower the fuel consumption by 25%. Just like current jet engines are twice as efficient compared to those built in the 1960s, this one, if applied on commercial airplanes, could offer significant savings in fuel and greenhouse gases.

100 Year-Old Aerodynamics Problem Solved: Could Increase MPG Dramatically

MIT researchers discovered the solution to a problem put 100 years ago by Ludwig Prandtl. It refers to the situation when, for example, a car accelerates up and down a hill, then slows to follow a turn, and the airflow around it cannot keep up and separates from it. This aerodynamic phenomena creates an additional drag, slowing the car, and forcing you to push harder on the pedal, consuming more gas.

According to Reuters, Nissan said on Monday that it has invented an accelerator pedal for their future cars that is somehow slapping your foot off it. It can push back on the driver's foot when it detects too much pressure and bad fuel efficiency while accelerating.

Aerodynamic Trucks Fight Diesel Rising Prices

While diesel is approaching $5 a gallon, researchers become more interested in finding a way to reduce fuel consumption on the heavy trucks at highway speeds. Now they have come up with an interesting idea: while there's little point in firstly modifying the engines to consume less, and spending a lot of money on upgrading them, the focus went on making the existing heavy weight trucks more aerodynamic.
