  1. Good News for Wind EnergyThe Racing Aeolus contest, the Inventus vehicle and the public acceptance of wind turbines Mark Capellaro1, Alexander Miller1, Tobias Klaus1, Jan Lehmann1, Sylvia Scheper2, L.G.J.

  2. Presentation Contents • Racing Aeolus – the contest • Universität Stuttgart and the Inventus wind vehicle • Design, Manufacture, Testing • PR and sponsors (Stuttgart) • Race Day! The race in Den Helder • Problems, results, winners... • Results and conclusions

  3. Public Acceptance: Difference between cute and not cute Same animal, scaled up. Public Acceptance: make things less scary. Acceptable, adorable and good PR

  4. Racing Aeolus and the ATO (Associatie Technologie Overdracht) Racing Aeolus Contest • Race a land vehicle, powered by the wind, directly into the wind • Promotion Event for the North Holland Province, Den Helder, NL • Race announced summer 2007 • Websites: www.ato.nl, www.windenergyevents.com Photo: E. Weßbecher • Held the same time as the Tall Ships Race (~300,000 visitors) Photo: N Hoppe Den Helder, next stop, the Shetland Islands

  5. Racing Aeolus • Six teams entered the contest • Most important rules: • Power storage devices to be empty at the start. • Dimensions • Max Height: 3.5m • Max Length: 4 • Max Width: 2m • Rotor safety mesh • Multiple brakes • Rotor brake (failsafe) • Wheel brakes • Regulations determined the design envelope Inventus Early Design Study

  8. Universität Stuttgart SWE Inventus Team Inventus Stuttgart entered early • Design starts late 2007 • Two student masters‘ project • Third team member for PR, sponsors, promotion • The design process brought in many interested students • Hands-on project utilizing their analytical skills and the IFB composite workshop • Many willing hands Photo: T. Klaus

  9. Inventus Design and Manufacture The IFB Laboratory has all the facilities to build the fiber composite components. Braiding technique The design was guided by the manufacturing capabilities at the IFB and the regulations from the Racing Aeolus organization. Photo: T. Klaus Photos: A Miller Braiding the frame

  10. Inventus Design and Manufacture The decision was made to create a standard turbine but surround it with a diffusor to maximize the incoming wind. The blades were designed in-house and designed to drive a wind auto (minimize thrust and maximize power). Photo: A. Miller Photos: A. Miller Photo: T. Klaus Pitch control, just like a commercial turbine Photo: J. Graf Photo: J. Graf Photos: T. Klaus Photo: A. Miller

  11. Inventus Design and Testing The Universität Stuttgart Institute for Aerodynamics and Gas Dynamics has a 6m diameter wind canal. This allowed us to test the Inventus rotor and vehicle on campus. A donated glider hull improved the aerodynamic results. Photo: N. Mittelmeier Photos: A. Miller Photo: J. Graf Source: N. Mittelmeier , T. Klaus

  12. Inventus PR The PR team was very pro-active. First press conference before a design was finalized “Land of Ideas“ prize was held on the University‘s annual Day of Science. Many interested visitors Interest grew as the race approached.

  13. Inventus and the Press Inventus and the Press

  14. Inventus Sponsors The press attention helped us gain support. Local suppliers helped out with discounts, know-how, advice (and the ability to suspend their disbelief). Other support came as training, design tips and ideas and funding.

  15. The Race - Racing Aeolus – Den Helder, NL

  16. The Race - Racing Aeolus – Den Helder, NL The teams that did manage to run also experienced (repeated) failures. (Prototype vehicles, steep learning curve.) The race: two teams at a time and against one another and the clock. However technical/design difficulties eliminated some competitors. Photos: N Hoppe Collapsed bicycle cassette gear. Too much power! Repair: Hands on student project!

  17. Results - Racing Aeolus • The race schedule was modified due to technical difficulties • 10 heats were run between the (race ready) vehicles. • With the repairs came improvements, most vehicles improved in speed and reliability. (This is a good sign for next year.) • Overall winner was Inventus Uni Stuttgart with a topic speed ratio of 65% of the wind speed (~20 km/h) • (3min 13 seconds over 1km against an average wind of 8.8ms (32km/h)) Photos: N Hoppe

  18. Conclusions: Public Acceptance and Wind Energy • Small scale allowed people to see the basics of wind power. • Lessons from the project • Great student project (see poster No. 35!) • Local companies very supportive of project. • People are more supportive of technology when they understand it (and benefit from it) Lessons from the race • Local teams drive local interest. • The spectators were very interested in the mechanics.

  19. Inventus, Aeolus & the next race • Racing Aeolus 2009 is the week of 17-21 August 2009 Open to all! • (No annoying Tall Ships Race to distract!) • Great opportunity to interest local companies, universities, students in a hands-on project. • Promotes wind energy, demonstrates the technology on a human scale. • Looking • forward to next year • for sponsors • towards the next rain storm Team Inventus (Blue) ECN Impulse (Yellow)
