How Small Engine Turbo Improves Fuel Economy
Typically, even a low-boost small engine turbo can deliver 25% more power than its non-boosted sister.
That means that even a tiny turbocharged i3 can...
US Army’s 7mpg HUMVEE Replacement, More Fuel Efficient
Military vehicles are in a class all their own, and the same is true for the US Army's HUMVEE replacement, which is rated at...
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.
OPOC: The Two-Stroke Engine Revived by Michigan Company Is Cleaner and More Efficient
EcoMotors, a Troy, Michigan startup company revitalizes the two-stroke engine, making it 50 percent more efficient than currently-used four-stroke engines and less polluting. Even Bill Gates and Khosla Ventures invested a total of $23.5 million in them.
Achates Power’s Diesel Engine Could be Twice as Efficient
The Achates Power engine could be twice as efficient than today's best engines, and could be used for the Army.

“Most Environmentally Friendly” Car Award Goes to: Mercedes Benz B200 CNG and BlueTec
German car magazine, Auto Test, has named the Mercedes Benz B200 CNG and the ML 250 BlueTec 4Matic as the most environmentally-friendly, giving them...
New Engine Prototype That Mixes Gasoline and Diesel Gets 55 Percent Efficient
Researchers from the University of Wisconsin-Madison have recently unveiled a concept engine that can be from 20 to 30 percent more fuel-efficient than classic models. It would also be substantially cheaper to produce, since the emissions are lower than those of conventional engines and expensive catalyst units are not needed any longer (in some cases, their price can reach that of the engine's).
New Waissi Engine Simpler and More Efficient, Arizona State University
The Waissi Engine is of an opposed-piston design, much like that being developed by Achates Power or EcoMotors, with one important difference: Waissi's engine...
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.
NASA’s “Flying Wing” Aircraft Prototype Twice as Efficient
While aviation engineers have long known that a “flying wing” aircraft would be more efficient than the traditional tubular fuselage aircraft we see today,...
