Minix wing tip device promises 6% gain in fuel efficiency for airliners

Fuel consumption and greenhouse gas emissions are huge priorities in the aviation industry – passenger airliners chew through amazing quantities of fuel. Take the Boeing 747, which guzzles somewhere around a gallon of jet fuel per second – it's clear that a percentile improvement in fuel consumption can make a huge difference to costs at the end of a long-haul flight. That's why the Minix wing tip deserves close scrutiny. It replaces the tilted winglets at the tip of an aircraft wing, can be retrofitted to any airplane, and smooths out the wing-tip vortex, reducing the aircraft's wing drag. Minix claims the design is five times more effective than a regular winglet and can save as much as 6% on an aircraft's energy costs. For a commercial Boeing 747, that equates to a saving of around 600,000 gallons of fuel per year, per aircraft. Food for thought.  Read More

A still from the just-released video of the ornithopter in action

Last year, we brought you the story of tech company AeroVironment’s life-size artificial hummingbird, that flies solely by flapping its wings. Now, a group of Japanese researchers has successfully built and flown a flapping-wing-powered swallowtail butterfly. Besides looking incredibly cool, the life-size “ornithopter” has also proven a principle that could have big implications in the field of aerodynamics.  Read More

Laval University's 2,487.5mpg NTF 4.0, crossing the finish line at the 2010 Shell Eco-Mara...

The NTF 4.0, a car built by a team of students from Laval University in Quebec, Canada, achieved an astonishing 2,487.5 mpg (US) a week ago at the 2010 Shell Eco-Marathon Americas in Houson, Texas. The feat earned the team the $US5,000 grand prize in the Prototype category, in which fuel-efficiency can be achieved through designs that are... well, that are as radically streamlined and lightweight as possible, really. The combustion-engined NTF (any ideas what that stands for?) was by no means the only impressive vehicle at the event, however.  Read More

Chevrolet's non-hybrid Cruze Eco promises 40mpg highway, comparable to the hybrid Honda In...

Next week at the 2010 New York Auto Show, Chevrolet will be unveiling the compact 2011 Cruze Eco. Visually, this car isn’t going to be big news – it’s OK, but nothing you haven’t seen before. With a six-speed manual transmission, however, it should achieve an estimated 40mpg on the highway – what Chevrolet calls “hybrid-like” fuel efficiency. With that kind of mileage, but without a hybrid’s complexity or price tag, the Eco could prove pretty popular. By comparison, the hybrid Toyota Prius and Honda Insight get 49 and 43mpg highway, respectively, while the non-hybrid Honda Civic sedan gets 34.  Read More

The DeltaWing, proposed to replace the current IndyCar chassis

Two of four submissions have now been unveiled by the companies wishing to produce the next generation of IndyCar open-wheel racers, and the most recent one is one of the most fascinating looking racecars we've ever seen. The DeltaWing is a radical departure from traditional open-wheeler design - in fact, the only thing you could really compare it to is the bizarre lovechild of a drag racer and a Batmobile. With its comically narrow rocketship front end, broad rear end and narrow tyres, the DeltaWing aims to outperform the current crop of IndyCars for significantly less money, while delivering extraordinary efficiency gains and leaving a clear airstream for following cars, in order to promote close racing and overtaking. But is the public ready for a car that looks... so little like a car?  Read More

Jacobs demonstrating his modified Honda Innova 125i

Adding a self-built aerodynamic outer shell to a brand new Honda Innova 125i big-wheeled, step through scooter has resulted in its already pretty impressive fuel efficiency being improved considerably. Experienced Dutch cycle designer Allert Jacobs has spent the last couple of years designing, building and tweaking his machine before hitting the road recently for the all important road test.  Read More

The Beyss Go-One Evolution

Picture it: You’re zipping down the road in a sleek, exotic vehicle that looks like it came straight out of Blade Runner. You pull up at a red light, and a gawking onlooker asks what sort of an engine it has. To their amazement, you open the top to reveal that it’s propelled by nothing but the superhuman power of your own body. Well, that fantasy can become a reality if you’re willing to spend several thousand dollars on a velomobile. There are a number of such vehicles being produced, but perhaps none are more lusted-after than the German Beyss Go-One3. That model may soon be upstaged, however, as Beyss is set to release their latest creation, the Go-One Evolution.  Read More

While windtunnels have long been employed in aerospace and all forms of race engineering, we’re likely to see them employed more frequently in future in the quest for improved fuel efficiency from our automobiles. Ecomodder.com’s Darin Cosgrove recently added this 1.37 tailpiece to his Pontiac Firefly to improve its drag coefficient from 0.34 to 0.23 and its fuel efficiency by 15.1 percent at 90kmh (56mph).  Read More

The Blunt Umbrella boasts improved strength, durability, stability and is safer than tradi...

Umbrellas have been around for thousands of years but, aside from the introduction of the collapsible umbrella in 1935, their design has remained largely unchanged - despite the well known design flaws that see them flip inside out in strong winds or threaten to take out an eye with their pointy rib tips. It was this threat to his eyeballs as he negotiated busy London streets in wet weather that set 1.9 m tall New Zealand designer Greig Brebner on a mission to design a better umbrella – a goal he believes he has achieved with the Blunt Umbrella.  Read More

GRACE incorporates Formula 1 and jet technology in a street legal e-bike

Combining jet fighter technology with Formula 1 grade parts and German build quality, the GRACE street legal electric two-wheeler will start to be shipped in limited numbers next year. As well as offering a couple of city travel options, GRACE is also available in an off-road version too. The company has even manufactured a demonstration-only racy model capable of speeds up to 70kmh (44mph).  Read More
