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.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
