No CommentsOguzhar Yalcin, a student at the University of Celal Bayar in Manisa, Turkey, explains the inspiration for his team’s solar car at Shell Eco-marathon Europe 2012 in Rotterdam.
The car is named for the “Manisa Tarzan,” the environmentalist Ahmet Bedevi, who is legendary for his work in the first half of the last century planting thousands of trees on Mount Spil, or Mount Sipylus in Manisa. Known by some as the “first environmentalist of Turkey,” Bedevi raised awareness of the need for protection of the Earth’s resources and remains a revered figure for the people of Manisa.
The Celal Bayar team, called EcoMagnesia, is one of 13 teams from Turkey entered in the fuel efficient car competition, only one of them running on gasoline. Six of the Turkish student vehicles were hydrogen-powered, three were plug-in electric, two were solar and one ran on GTL, or natural gas-to-liquid diesel fuel.

No CommentsMany 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 city name, Trier) wanted the number 701 for its battery electric urban concept vehicle, Jungbluth said. That’s because the number “7″ stands for the class of battery the car uses and the “1″ stands for the first place the team took Eco-Marathon 2011, with a result of 233 kilometers (145 miles) per kilowatthour. Because 1 gallon of gasoline delivers the same energy as 33.7 kilowatthours of electrical power, that works out to the equivalent of 4,887 miles per gallon, or 2,078 kilometers per liter. The course this year is more difficult, on a city street with rough surfaces and many sharp turns instead of an oval race course. In early results, Trier’s vehicle achieved 172 kilometers (108 miles) per kilowatthour, or the equivalent of 1,548 km/l (3,640 mpg) on gasoline.

No CommentsStudents 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 gasoline is colored blue and is stored in clear glass containers so that it can be easily measured, down to the milliliter.
One of four teams in the competition from Poland, Warsaw University’s SIMR Team has named this car Hussar, after the legendary Polish cavalry that gained a reputation of invincibility for its victories on numerous battlefields from the 16th through the 18th centuries. The cavalry charge in this race is for fuel economy, and in last year’s competition Hussar achieved 320 kilometers per liter (753 miles per gallon.) Below, drivers Koniczu Polozynska (left) and Agata Marta pose in front of the vehicle. “We cannot wait to start and set a new record,” says Marta.

No CommentsMany wild places The Wilderness Society is working the hardest to protect are areas near towns and cities that are ahead of the curve on the energy efficiency front. Take Pitkin, Gunnison and Eagle counties near the Mount Massive Wilderness Area in Colorado. By working with organizations like the Community Office for Resource Efficiency (CORE), thousands of businesses and residents in these counties have taken action to reduce energy use through innovative programs implemented at a local scale. What does this electricity savings translate to? Fewer new power plants and transmission lines across the land—by reducing demand for a new 1000 MW coal‐fired power plant, we can save roughly 23,500 acres from development.
Yesterday, I had the pleasure of attending an event hosted by the Alliance to Save Energy—an organization that brings together businesses, government, environmental and consumer leaders around the common cause of energy efficiency “as a means to achieve a healthier economy, a cleaner environment and greater energy security.” Founded in 1977 by a bi-partisan group of Senators, the Alliance has been witness to a doubling of U.S. energy efficiency per GDP over the past 35 years, and that message of energy efficiency as a way to cut costs seems to have permeated some of the biggest utilities and Fortune 500 companies in America.
In light of our “almost do-nothing Congress,” this event was a CFL light bulb in the wilderness—bringing together business leaders and elected officials to suggest that when it comes to energy efficiency (as Congressman Peter Welch of Vermont put it) we should go from “politics to pragmatism.” Legislation such as the Shaheen-Portman Act—which enjoys the support of the National Association of Manufacturers, among others—would set new standards for existing energy efficiency technologies in the residential, commercial, and industrial sectors of our economy. Leaders at the event including Senator Mark Warner and Thomas Kuhn, President of Edison Electric Institute, called it an easy bill to support. Why? Because energy efficiency just makes sense, whether you care about profit margins or wild places.
In fact, Cal Dooley of the American Chemistry Council suggested at yesterday’s event that it is imperative we reduce the pool of needed energy while debating how to transition away from fossil fuels. In some landscapes, this concept is taking hold. States near New England’s pristine Northern Forest—Vermont and Massachusetts—rank amongst the top five states in the county on ACEEE’s 2011 state annual scorecard on energy efficiency. These are steps in the right direction, but we can and should do more. To address global warming impacts on wild places, we will need new renewable power plants—and at TWS we are working to be sure they are responsibly sited. But if we are serious about protecting wild places, beautiful landscapes, and biodiversity, particularly in areas with smaller landscapes and lots of energy demand, it is the task at hand to find no regrets solutions to reducing energy use, and reducing the need for new power plants.
Despite the political challenges ahead, I felt quite positive coming out of a morning spent at the Alliance to Save Energy surrounded by businesses who want to do more than “good guy stuff,” as Senator Mark Warner put it. These businesses want to use energy efficiency to maximize profits, maximize their return on investment, and maximize their global competitiveness. And just when it couldn’t get any better, Bruce Ray, Director of Government Affairs for Warren Buffet’s energy efficiency company Johns Manville, stood up to spread Mr. Buffet’s recent and now famous call to invest in “people, communities and the environment”—something I blogged about just last week. Perhaps on ideas like energy efficiency, the environmental community and the private sector are more aligned than I thought. If folks only realized that saving energy also saves lands, we might put the cause over the edge. That makes good business sense to me.

No CommentsNicole Miranda, a first-year doctoral student at the University of Oxford, practices her vehicle exit technique and timing at Shell Eco-marathon Europe 2012 in Rotterdam. She is assisted by fellow student and driver, Lucy Mahoney. (Often female students serve as drivers in the fuel efficiency competition because they weigh less than the men on the team.)
This is the first year of competition for the United Kingdom’s storied school, and the team has had to improvise, says manager Justin Bishop. They used the shell of a vehicle that already had been built by another student team in 2006, modifying it and including the needed safety equipment. But the predetermined shape of the car meant they couldn’t bury or sink the wires of their battery electric vehicle, but had to feed them around the narrow driver’s cabin, Bishop explained.
The team’s car is named “PEGGIE,” an anagram (of sorts) for students’ program at Oxford, the Electric and Power Group (EPG). The students are deeply engaged in energy issues, and Bishop himself is a James Martin research fellow working on a project to determine the future make-up of the light-duty vehicle fleet.

No CommentsRomain Lejas, of
Ecole Polytechnique in Palaiseau, France, works on InfinitiX, the team’s entry in Shell Eco-marathon 2012 this week in Rotterdam. Last year, the team achieved 454 kilometers per liter (1,067 miles per gallon), and this year sought to reduce weight more.
The car is entered in the “prototype” category—these don’t have to be street-legal. Typically the students seek extremes in aerodynamics and light weight to reduce mileage in the race for the most fuel-efficient vehicle.
Lejas is in one of the student team “paddocks” at the huge Ahoy convention center. More than 2,000 students from some 20 countries are here for the three-day competition that ends Saturday.

No CommentsThe drive for a new and better way of doing things is built into the car designed by students from Italy’s Italy’s Politecnico di Torino, and entered in Shell Eco-marathon Europe 2012 this week in Rotterdam.
Most students in the fuel efficiency competition choose ultra-lightweight material like carbon fiber to shave mileage. But for their urban concept vehicle, XAM, the Torino students chose a soft natural fiber, covered with a resin to make it hard enough to serve as a chassis. It is not as lightweight as carbon fiber, says electrical engineering student Francisco Fuentas, but it is 100 percent recyclable. “The reason is innovation–we wanted to prove new materials,” he says.
Also, the team, which calls itself “Team H2politO—Molecules Going Hybrid” and includes 53 students, has installed a hybrid gasoline-electric system that uses a “supercap,” – a supercapacitor—instead of a battery. It carries greater current and lasts longer. “We think we are studying a new possibility,” says Fuentas. In the commercial world, supercapacitors are still considered expensive, but the technology is advancing rapidly and it is thought they may replace or supplement batteries in a growing number of applications, including in vehicles.
In this video, Fuentas, a native of Colombia who earned his electrical engineering degree in Bogata but is studying for his master’s degree in Torino, talks about what students gain from working on the fuel efficiency competition.

No CommentsStudents from Spain’s La Universitat Politecnica de Valencia (UPV) do some final testing on “Urban Spirit,” the car they hope will help test new possibilities for fuel efficiency in Shell Eco-marathon Europe 2012. The Valencia team is one of 154 teams from some 20 countries gathered in Rotterdam this week for the student design, build, and drive competition.
The goal isn’t to be the fastest car, but to be the most efficient; still, the Urban Spirit UPV team has been inspired by the world of sports car driving. The students have integrated the same aluminum honeycomb glass fiber into their car as is used in the GTA Spano, the Spanish supercar built in their own city of Valencia by GTA Motor. “It’s easy to design with and makes a strong chassis,” says fifth-year student Javier Gonzalez, “Of course, it’s very expensive.”
The team is hoping the new ultra-lightweight material helps lift it beyond its performance last year of 146 kilometers per liter (343 miles per gallon). But this year’s track will be more difficult, on the city streets of Rotterdam with five 90-degree turns. Previously, Eco-marathon Europe was held on a circular race track, last year, in Lausitz, Germany.
Because every bump and turn in the road eats up more fuel, it will be more challenging to achieve high gas mileage on city streets. But the race organizers wanted to aim for conditions closer to what ordinary motorists face. And the Valencia team is entered in the category of the competition that is also meant to mimic real-world conditions, the “urban concept” vehicle class; the students in this category need to build vehicles that are street legal. (They even had to include windshield wipers this year for the first time.)
