New OCN Jet Engine Sips 25% Less Fuel and Outputs 75% Less Greenhouse Gases

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.

Ford Developing Laser Powered Spark Plug for Future Engines

The auto industry is pursuing various ways to implement more effective fuel saving strategies. Some of them are based on the development of new technology, electric motors, batteries, etc and others are just improving classic petrol-fueled engines to run better. Following the second trend, engineers from The University of Liverpool, UK, in collaboration with Ford and UK-based GSI Group developed a prototype engine ignition based on lasers rather than on spark plugs.
