Directory:Fuel Efficiency > 50 MPG Plane Wins PAV Prize - The Pipistrel won NASA's Personal Air Vehicle X-Prize like contest, achieving 50 MPG. The plane is extremely light weight, so it becomes more fuel efficient as it flies and burns fuel, getting lighter. The plane's simple controls and ease of operation also helped it take home the prize. It costs about $70,000. (EcoGeek Aug. 15, 2007)
Directory:Fuel Efficiency > Directory:Fuel Efficiency Vehicles > 9 Steps to Cheaper Greener Flight - The Boeing 787 Dreamliner is the first commercial jet produced with efficiency specifically in mind, but the 787 still leaves a lot of room for improvement. Several designs are at various stages of production that could make air travel as efficient, or even more efficient, than automobiles. (EcoGeek Jul. 26, 2007)
Directory:Fuel Efficiency > Directory:Fuel Efficiency Vehicles > Ohio Airships - The Dynalifter® “Roadless Trucking?? system has transport costs and speeds comparable to trucking without the need of building a sophisticated highway network. It has the ability to fly on low amounts of power at low speeds, much like airships, but without the operational drawbacks of a traditional airship.
Directory:Fuel Efficiency > Directory:Fuel Efficiency Vehicles > Silent aircraft creeps closer to reality - Researchers from Cambridge University and MIT unveiled their concept for a flying wing aircraft that makes a huge reduction in noise. This highly-efficient design offers improvements of around 25% in fuel consumption and is intended for entry into service in 2030. (The Cambridge-MIT Institute November 06, 2006)
35% More Efficient Flight - Bauhaus Luftfahrt is promising emissions cuts of 35% by 2035, to meet the European Union’s Clean Skies initiative. They propose adoption of geared turbofans in conventional engines for 15%, then counter fans for 5%, and waste recuperation for another 15% efficiency. Bauhaus is also working on a box-winged aircraft for further reductions. (EcoGeek Feb. 14, 2008)
