Comments Off on Loyola Marymount’s Bamboo Car, Battered by Heat, Still Takes the Track

The effort to go green in building materials added to the challenges for the Loyola Marymount Senior Mechanical Engineers team at Shell Eco-marathon Americans 2013. Senior Van Weller explained that the team chose lightweight bamboo for the body of its gasoline-powered prototype vehicle, the Gen 5, and spiffed it up with gold paint. Unfortunately, the…

Comments Off on One Fuel-Cell Assembly,Two Hydrogen Cars for Cicero-North Syracuse

Students at Cicero-North Syracuse High School are demonstrating an innovation in flexible vehicle design with the hydrogen vehicles they built for Shell Eco-marathon Americas 2013. The CNS Performance Engineering Team fashioned its hydrogen tank and fuel cell unit, shown in one of the photos above, as a modular, removable unit that can be moved back…

The ethanol mandate in gasoline is starting to sting.

We recently took a look at the new electric cars that are charging into the automotive market, despite the obstacles they still face in displacing the gasoline-powered vehicles that are still king of the road. One reader raised a simple, but excellent question, because it really is at the heart of why EVs are expected…

No less an authority than the International Energy Agency says the world could cut the fuel used for road transport in half over the next 40 years. The question is whether anyone is willing to do the work needed to get there. Fully one-fifth of all energy use worldwide is for transportation, and transportation is…

Comments Off on Better Fuel Efficiency, but More Cars Than Ever on the World’s Roads

Even as cars become more efficient and fuels become cleaner, the sheer number of vehicles on the road and the distances we travel in them may overwhelm whatever gains the world achieves in fuel economy, according to a new report from the Worldwatch Institute. World production of passenger cars has rebounded from the dip seen…

Laurens van Mulukom, a mechanical engineering student at Hogeschool van Amsterdam, talked about why hydrogen is “one of the most innovative fuels to work with,” at Shell Eco-marathon Europe 2012 in Rotterdam. With this year’s competition that ended Saturday taking place on its home country’s soil, <a href=”http://www.h2a.nu/h2a-news/”>Team H2A</a> was proud to achieve a new…

Comments Off on Stirling Engine: External Combustion Efficiency

One of the most unusual looking cars at this year’s Shell Eco-marathon Europe was testing out one of the oldest concepts for harnessing energy for motion: the Stirling heat engine. Team Schluckspecht from the University of Applied Sciences, of Offenburg, Germany, designed a vehicle that relied on external heating and cooling to drive pistons. The…

Comments Off on Trier: Practical Experience in Efficient Design

Many engineering students, like Matthias Jungbluth of Fachhochschule (The University of Applied Sciences) Trier  in Rheinland-Pfalz, Germany, are attracted to a project like Shell Eco-marathon by the hands-on experience involved in designing and building a fuel-efficient car. The Trier school’s team, called team ProTRon (a combination of the word “protype” and the abbreviation for the…

Comments Off on Warsaw: Hussar Charge for Fuel Economy

Students from the Warsaw University of Technology in Poland conduct some final technical tests on their vehicle at Shell Eco-marathon 2012 in Rotterdam. Cars in the fuel efficiency race need to pass a battery of safety tests, including on the fueling and exhaust systems, the braking and steering, and the solidity of the chassis. The…
