Tomorrow's Engineers Push Fuel Economy Limits in Shell Eco-marathon

(3BL Media/Justmeans) - Last week I wrote a guest post on GM's Fast Lane blog on the future of transportation. The post examined some concept vehicles that GM has been testing that can communicate with each other enabling them to move down the road in synchrony, like a flock of birds or a school of fish might. This would not only improve safety but could also speed things up quite a bit while saving energy at the same time.

Over the weekend, I took another peek into the future as a visitor to Shell's Eco-marathon in Houston. Even if the slick little cars I saw quietly parting the sultry Houston air do not represent the shape of vehicles to come (though I suspect some will), I'm pretty sure I saw some of tomorrow's engineers and innovators in action in the paddock area, working feverishly to get their cars ready to compete. The students designed and built the cars entirely themselves, though they were allowed to work with mentors. The contest goal was to achieve the highest fuel economy.

There are two vehicle categories: prototype and urban concept and six eligible fuels: gasoline, diesel, ethanol, gas-to-liquid, battery electric, and hydrogen fuel cell.

The event goes back to 1939, when two shell engineers wagered over who could build the most fuel efficient car. The winner managed a respectable 49 mpg. This year's winners did quite a bit better.

Montreal's Université Laval’s Alérion Supermileage team took the top spot in a gasoline-powered car that achieved a fuel economy of 2,824 miles per gallon with their prototype vehicle. That would allow you to circle the globe at the equator on a little under 9 gallons, though I can't say it would be a particularly comfortable ride. As impressive as that sounds, it did not top the record set by the same team last year which was 3,587 mpg.

The urban concept category also saw a repeat by last year's champs, Mater Dei High School of Evansville, Indiana, who did manage to set a record in that category of 901 mpg.

All together some 126 teams participated from 5 countries. This was the Americas version of the event which also has counterparts in Europe and Asia. The 94 prototype vehicles consisted of 63 combustion type (including ethanol, diesel and GTL), and 31 electric (including fuel cell). There were also 32 urban concept vehicles.

Sustainability in the Spotlight

stopshellWe all love to find out that our favorite actors and movie stars are also committed to the environment. Hollywood has its fair share of greenies. Woody Harrelson is a committed vegan eco-hero, and used to run an organization called Voice Yourself to promote sustainable, organic living.
