Dana and Lorena Ruisi of Universidad Cardenal Herrera’s Idea Ceu Team from Spain explain that their team took inspiration from nature for the shape of their car entered in Shell Eco-marathon Europe. Their vehicle is shaped like a rain drop. They believe falling rain is one of nature’s most efficient means of movement, and they believe it will prove to be a very natural and efficient method of moving their electric and solar-powered car around the track. After early runs, their vehicle was in second place in its category, with 604.36 kilometers (375.54 miles) per kilowatt-hour, the energy equivalent of 12,655.7 miles per gallon (5380.5 km/l.)
About the Road to Eco-marathon
This sub-section of the Great Energy Challenge Blog features the stories of high school and college students who have spent much of the past year focusing on the problem of building vehicles that use less fuel. They are participants in Shell* Eco-marathon, a competition on three continents to design, build, and drive the most fuel-efficient car.
