Racing the extremely stylish and lightweight three-wheeler, the vehicles of five European universities and research centres had difficulties to catch up. For their “innovative design” and their “PR” work, the InVentus team were also awarded prizes .
The ECN-impulse built by the Energy research Centre of the Netherlands (ECN) came in second. The Flensburg University of Applied Sciences won the third prize with their very solid but slow Headwind Tricycle. In this first time ever race the participating teams were challenged to drive directly into the wind, without tacking. During the preliminary races, the Stuttgart Ventomobile had already proven to be the most lightweight and most efficient vehicle among the contestants when, with its 130 kg, it succeeded in racing at 64% of the wind speed directly against the wind. From then on it was considered a serious contender for the win.
„Winning this prize was a great reward for our intense construction work during the last few months“, Alexander Miller is thrilled. Cooperating with some 20 students, he and Jan Lehmann developed and constructed the vehicle from Summer 2007 onwards with the support of the Endowed Chair of Wind Energy at the University of Stuttgart. The students constructed the drive shaft and the rotor blades of the three-wheeler utilising the know-how at the Stuttgart University Department of Composites and Lightweight Construction. The experience of the students and the staff at the Institute of Aero- and Gasdynamics also helped greatly in optimizing the vehicle. The carbon-fibre-built tower can be turned into the wind, and through pitching the blades can be adjusted optimally to the wind speed. Via two bicycle gearboxes and a bicycle chain the power then is transmitted to the axle.
Matthias Schubert, Chief Technical Officer of the main sponsor REpower Systems AG, applauds the integration of this project into the coursework of the students: „The achievement of managing a big team over many months, and even making select construction tasks part of undergraduate teaching cannot be estimated highly enough! The enthusiasm the students show in renewable energies and the development of innovative solutions should serve the industry as an example for the development of new technologies.“
Prof. Martin Kühn, head of the Endowed Chair of Wind Energy and mentor of the InVentus team, is pleased about the success of his students. “The expert knowledge the students acquired during this project constitute an unique experience which will prove extremely helpful in their future careers. The Ventomobile and its competitors represent excellent and creative examples of intelligent uses of wind energy“, he points out, at the same time promoting a better use of renewable energies.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
