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.

Revetec Controlled Combustion Engine: 50% less fuel, 100% power

A better combustion engine is the one recently patented by Revetec, a small company from Australia. Their engine has been tested by independent parties. It has the same power as an ordinary engine, but it consumes half the fuel and it weights 50% less. It's also smaller than the average car engine.
