Our engineering geniuses from Team InVentus have got a tail wind: Right now, every screw in the “Ventomobil” is being thoroughly tested, in order to prepare the wind racer for the big Aeolus Race in Den Helder (August 20 to 23). While the heart and kidney checks are running, a chassis design is also still being sought! And because the Ventomobil is destined to generate a whirlwind of excitement, as it were, we brought a proven professional together with the team representing our hopes for the future: Check out InVentus talking to BMW designer Stephan Augustin!
InVentus: How much work is involved in constructing a chassis? How many labor hours should we calculate?Stephan Augustin: You can’t really make a sweeping statement as to the amount of work required for the construction of a chassis. Generally, it involves a lot of time. However, the objective of the project is the clever construction of the engine. For that reason, I wouldn’t invest too much in it here.

InVentus: What is the best method of construction for a chassis?Stephan Augustin: The best option is to use fabric, film or elastic membranes. These are pulled over a ribbed frame, similar to old aeroplanes.
Consequently, the vehicle is very light, and also looks attractive due to the minimal surfaces. Plexi should only be used in areas subject to substantial stress. InVentus: How significantly is air resistance reduced through the use of a simple fairing in our current model?

Stephan Augustin: That depends entirely on the front surface of the vehicle, but generally every fairing is an advantage, even at lower speeds. The use of membranes is also completely sufficient, particularly at low speeds. The Ventomobil - still naked without chassis
InVentus: Should you already have the design in the lead-up to construction, or simply get stuck straight into the vehicle?Stephan Augustin: Getting stuck straight into the vehicle might be a bit risky. I would prepare a small model with the basic geometry, and then design the external skin with wire and nylon stockings, just like Frei Otto did for the design of the Munich Olympic Stadium. Then replicate it exactly in construction.
And by the way: There's still a lot to do! You can help us to bring the Ventomobil on the streets. Test drive the Ventomobil and give us your feedback - or bring up your idea of a chassis design for the Ventomobil.

Your help would be appreciated!

Ladies and gentlemen, we proudly present the Oscar for innovative ideas made in Germany: Within the scope of the Day of Science at the University of Stuttgart, we received the Land of Ideas Award for pioneering projects!We want to thank you for your support with some pictures of our big day! Watch also our video of the public presentation of the Ventomobil! Stay tuned, pioneers!

We called for your help, and you delivered! Thanks a lot to Fabian a.k.a. Thälmannpioneer who answered our call and sent us some great designs for an InVentus T-Shirt!! Click the slideshow to see the hot drawings and read Fabians explanations!

Would be great to read about your impression - Tell us which design you like best by commenting this blog!!We also got a design from Kerstin and Julia some friends of us at the University of Stuttgart - a little more formal, but also cool... by the way, it's quite small but note the Club of Pioneers Logo at the sleeve;)

The day has finally come: After eight months of hard work we have presented the prototype of the ventomobil to the public! The respond was fantastic: People are really enthusiastic about the concept to use the wind to drive against the wind - and last but not least we received the Land of Ideas Award for innovative projects made in Germany!Watch the first performance of the Ventomobil - exclusive, in colour and almost in motion!
