Continuing on with our top three winning teams arriving at Victoria Square in Adelaide, Australia, Quantum team members of University of Michigan of USA presented us with Michigan’s eleventh generation car by completely revamping its design strategy. The team was able to take off 200 lbs from the previous vehicle weight and reduced the aerodynamic drag significantly.  Combining the engineering improvements and smart driving strategy, with a strong family members’ support, it is no wonder that this team is widely recognized as the best team in North America and being able to come in as one of the top three winning teams in the Veolia World Solar Challenge 2011.http://www.youtube.com/watch?v=5E6yO30-5Q8 The positive energy of these three top teams’ members is palpable as they all hopped into the Victoria Fountain, in full exuberance.  I even caught one of the University of Michigan team members’ successful attempt at reaching the top of the fountain on film, seen in one of the photos below, along with an interview with one of the female members and driver of the team, Rachel Kramer (yes, there are female drivers/pilots in Veolia World Solar Challenge 2011 !):

Veolia World Solar Challenge 2011-Day 5-Winning Team Tokai Challenger 2 Arrives At Angle Vale & Victoria Square

Share

Dear Readers,

I am interrupting (will post Day 3 & Day 4 later) to report about the winning team, Tokai Challenger 2 of Tokai University of Japan, which had just arrived at Victoria Square of Adelaide, Australia, within the last hour. The official finish line is located at Angle Vale, Australia, approximately 40 km outside of Adelaide (to avoid too much traffic lights), another brilliant decision on the part of the organizing team of Veolia World Solar Challenge 2011. So, as we waited at the Victoria Square, the ceremonial finish line, we chatted with and shared our excitement with some of the participants who have been loyal supporters of this solar car race for more than eighteen years. Despite the cloudy day with drizzle, our enthusiasm was not wavered the least bit. This is the special part of being solar participants, we/they are all full of extra dash of magical energy…perhaps a gift from the Sun…chuckle….

Here, we have a five-minute clip of interview with one of the winning drivers of Tokai Challenger 2 of Tokai University of Japan.

 

Even with the bush fire that they had to deal with, these winning drivers ended up averaging more than 91km/hr. They are so full of adrenaline that by the time they arrived at the Victoria Square, they did not hesitate to hop and hop

at the request of various reporters and of course the finale of hopping into the Victoria Fountain at Victoria Square. At the end of such a long journey through the desert of the Outback, one can fully appreciate/understand how this “Ritual Dip”  got started. But on a cloudy day with a touch of drizzle such as today, we thank our winning team in continuing this tradition in showing their exhilaration, undeterred by the rain.

We are very pleased that Tokai Challenger 2 of Tokai University (from Japan) is the winning team and are not too surprised by the outcome, for they have replaced the unique single-crystalline silicon solar cells with space grade solar cells. They have kept their winning design concept from 2009 but improved the efficiency. I read that the Tokai Challenger had a drag coefficient of 0.11 whereas University of Michigan had a drag coefficient of 0.10 Keep in mind that drag coefficient is a dimensionless quantity used to quantify drag or resistance of an object in a fluid environment (be it air or water), so a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag/resistance, which would be better for a car in a car race ( or anything that moves). With a 10% difference in drag coefficient, University of Michigan should be in a more advantageous position, if solely based on drag coefficient (lower drag coefficient value). So my question here is: does Tokai Challenger 2 now has a different drag coefficient from 0.11 or are there other factors that had been more important than the 10% difference in the drag coefficient? If any of you out there who knows more about solar car race, please let me know.
