Efficiency enthusiast Allert Jacobs converted his brand new Honda motorbike into a streamliner capable of reaching 214 mpg.

Jacobs was already getting 114 mpg with his Honda Innova, but knew some aerodynamic mods could get him so much more. Aerodynamics hugely impact fuel consumption. In fact, a typical car burns 50-percent of its fuel just overcoming the air resistance of going 40 mph! For a typical motorbike, this is just 20 mph.

Some people will go to great lengths to get the best gas mileage possible. There are simple ways of doing this of course, like using a light touch on the gas pedal and coasting whenever possible. If you’re mechanically inclined you can retard the timing or even perform an engine swap in pursuit of high MPGs.

Or you can add a hideous duck tail to your geo metro. Hey, whatever works, right?

Puff (a car exhaust monitoring device) is attached near the exhaust pipe of your vehicle. Its color changes dynamically, visualizing the amount of pollution your car is producing. Green indicates the lowest rate of pollution, red the highest. Karolina Sobecka, the artist/designer of Puff, explains: In this project, design is used as a strategy to explore the overlap between the material and immaterial worlds and spur discussion on the hidden social and psychological mechanisms behind the cultural use of accessories [...]

It certainly is the dawning of a new era in automotive technology when the tiger in your tank becomes a moldy relic of bygone ad campaigns while the humble leftovers from harvested wheat get awards for new sustainable thinking. A. Schulman, Inc.’s AgriPlas wheat straw fiber has just been named a Blue Ribbon Finalist in Environmental Innovation by the Automotive Division of the Society of Plastics Engineers, for its application in the Ford Flex crossover vehicle.

AgriPlas’s contribution to the Flex is an injection-molded storage bin and inner lid made of polypropylene and a bio-filler made of wheat straw. Though the application is modest in scope, a spokesperson for Ford’s Plastics Research division sees it as a litmus test of things to come, in terms of increasing fuel efficiency by decreasing vehicle weight.

The tapering tail is no secret among scientists for improving stability and fuel efficiency. Many high-mileage concept cars feature just such a design to smooth the aerodynamics of the vehicle. Now imagine applying the same concept to container trucks that log more miles in a year than most of us travel in five.

A Dutch public-private enterprise did just that, adding a 6 foot long tail to the end of a tractor trailer truck. The results from two years of testing were a 7.5% increase in fuel efficiency, and thus a similar decrease in emissions.

One of the great challenges for automakers today is determining which technology or group of technologies will be the most effective in increasing fuel-efficiency and lowering greenhouse emissions - while still meeting the performance, quality and price car-buyers expect. The array of choices available and under development is significant, ranging from turbo charging, direct injection, six speed transmissions, electric power assist steering, weight reductions, electrification, bio fuels and hydrogen fuel cells.

We know there is a viable future for some of the most advanced technologies, but we also recognize not all of them are market-ready or affordable for consumers. Even advanced technologies take time to gain widespread acceptance. For instance, despite mainstream acceptance of hybrid technology, hybrids remain less than 3% of the market.

Recently accusations came to light that Nissan and GM to inflate their MPG claims by combining gas and electric mileage so their green rating appeared higher, and in order to ensure that the Environmental Protection Agency  won’t follow in their alleged footsteps, The Society for Automotive Engineers and the National Renewable Energy Laboratory are recommending two different rating systems for electric vehicles that plug-in and also run on gas.

At the U.S. Air Force Academy in Colorado Springs, cadets are working on a new wing design for the KC-135 Stratotanker that could significantly increase fuel efficiency for the venerable aircraft.  Illustrating how small changes can make a big difference, the secret is in subtle, almost invisible adjustments to the wingtips, using wing designs from other aircraft as a template.  As for concentrating on the rather unglamorous Stratotanker, it makes perfect sense to put some extra energy into designing an aerial refueler that delivers more fuel and consumes less, especially with the development of new sustainable energy sources in view.

By most accounts, the Obama administration’s “Cash for Clunkers” program is a resounding success.

Barnacles, algae and other marine biofilm can reduce a ship’s fuel efficiency by up to 40%, and the U.S. Navy is working on a way to keep its hulls clean without using expensive chemicals.  Up to now, the Navy has been relying on biocides to keep the pesky hitchhikers at bay.  On top of harming marine life, the chemical regime is not ideal for keeping high-performance warships operating at peak efficiency.  The Navy estimates that it spends an extra one billion dollars yearly on chemical biocides and extra fuel, so in addition to pure environmental altruism there are significant tactical and bottom-line incentive to find a better way to prevent biofouling.  In what can only be described as poetic justice, naval researchers are turning to the marine environment itself to find safe, effective solutions to the problem.

With the fluctuating price of oil, a finite resource, and concerns over CO2 emissions, many energy companies and developers have turned to utilizing biomass as alternative fuel (biofuel). This trend is actually taking two pathways: using biomass to convert to ethanol to power automobiles (which has been around for awhile now), and, converting biomass to electricity to power electric (or hybrid) vehicles (a more recent alternative). The question of which path is most efficient, sustainable, and less carbon-intensive is an [...]
