coondoggie writes "Solar race cars this week began their nine-day, 2,400 mile chase from Dallas to Calgary, Alberta using only the sun for fuel. The 24 teams in the American Solar Challenge race are mainly US college teams including entries from MIT, Ohio State and Northwestern. The University of Michigan's Continuum car is the defending champ, having won the Challenge in Australia last year. The University of Michigan has won four out of the eight North American Solar Challenges it has entered with its team of more than 100 engineering students, who have vowed to defend their title this year."

      I wondered why they said "Dallas to Canada" when it was obviously starting in Plano, which, while near Dallas, is not, in fact, Dallas.

      The kids were all very eager and informative. Good luck to them that's still in the race.

    Michigan did not win the 2007 World Solar Challenge. Team Nuon did so with their Nuna4.

    Michigan won the 2005 American Solar Challenge race by about ten minutes over Minnesota.

        When I'm not at home in Chicago, I'm at my place in Rolla, MO, where I've seen the talented youngsters from Missouri U of Sci & Tech working on their solar vehicle. It's been nearly a decade since I first saw their sun car, and maybe, finally, this country of 300 million hunks of iron junk on wheels is ready to think about other ways of getting to Wal-mart to do their shopping besides relying on fossil fuels.

        What do you think, has $4.59/gal gasoline changed any minds yet? My family has downsized to a '95 Mazda that spends most of the time in the garage, but then we live in downtown Chicago where you can walk a few blocks from any point in town and pick up a bus or train in about 5 minutes. Or, and this is what we've chosen, we can hop on our bikes and give the big fungoo to the oil companies (at least when it comes to transportation). Living just blocks from campus or working from home makes it a lot easier, but I'm thinking there are other people making similar decisions to ours. One thing I've learned is that I'm not all that exceptional, so if I can get by without visiting a gas pump every week there are other people doing the same.

        Getting back to the solar car race, I just hope the media makes the story more than just an end-of-the-newscast cute item. We need to learn there's other ways to do things, and it feels so good when I cruise by the gas stations on my bike. I like to see the sad faces of the doofuses in their '07 Escalades or Tundras or whatever they're calling those stupid locomotives-on-rubber these days, as they watch the numbers fly by on the gas pumps. Fuck 'em for being stupid, I say. Plus, it makes them a little less cocky and agressive when it comes to sharing the street with my infinite-miles-per-gallon velocipede. Maybe at some point I'll start to have a little human sympathy and understanding for them. But not yet, not yet.

      Michigan was poised to win the 2007 World Solar Challenge until they crashed into their lead support vehicle. Their lead had to break hard after being cut off by STANFORD's support vehicle, which was panicking after they lost their solar car in the heavy Darwin (Australia) traffic. Next time your team enters an international event, please practice driving your race caravan in traffic.

      Congratulations on winning the 2005 stock race on a car largely based on Michigan's (embarrassing) 2003 car- one of your lead mechanical designers was a UM veteran.

        I can see that.

        Solar car is about building experience and becoming better at what you do. You can't fault a guy for learning from his mistakes and doing things better the second time around. What is an education for?

        UM has lost focus of the spirit of the event. This is a race, but it's not a race to a finish line. It's a race to learn as much as you can in the limited time you have as an undergraduate in a club activity.

        Michigan wants so badly to win that they realize needlessly risky designs to pursue fleetingly small perceived advantages. Gaming the race framework and then blaming the outcome of borderline engineering on others is bad form and is representative of the poor sportsmanship that has given the team such a bad reputation in the solar car racing community.

        Now, that is not to say that everyone on the UM team is a bad person. There are many fine engineers and upstanding people on the UM team, but their good work, high spirits, passion for the sport, and good conduct are easily eclipsed by the few members of the UM team that don't hold those values as highly.

        I would like to point out that the race officials concluded that Stanford had no culpability in Michigan's accident. Observers from both teams provided the details to reach that final decision.

        Maybe next time UM shouldn't use brakes designed for a bicycle on a solar car.

Having a longer race will expose the teams to greater variety in conditions, and this can only be a good thing.

      Calgary is one of the sunniest cities in North America in terms of amount of sunshine per year. Southern Alberta is, in large part, a semi-arid region with very low humidity, so the Sun really packs a wallop here due to very low atmospheric extinction. At this time of year the days are also longer the further North you go. Those cars will probably make better time once they cross into Canada than they will in most parts of the U.S..

      However, Alberta isn't really a solar energy hot-spot. Wind power is where it's at. Alberta produces more wind power than any other province in Canada. Whichever racers have the foresight to pack a sail will probably make the best time on the last leg of their journey.

        I'm not sure the rules in a solar race allow for wind sails, but even if they did the weight penalty of carry the sail all the way from Texas combined with the fact that the prevailing winds across the Canadian praries from Winnipeg to Calary are westerly, and the the cars are going the wrong way.
      • Actually I remember a graph from the race last year (or the year before?) showing that the speed in Alberta was about half what it was in Arizona. Southern alberta might have more hours of sunlight because of the latitude, but the sun is at more of an angle, so the light is dimmer.

    In 2001 the Nuna of the Delft University of Technology from the Netherlands, participating for the first time, was the fastest.

    In 2003 the Nuna 2, the successor to the winner of 2001 won again, with an average speed of 97 km/h (60 mph).

    In 2005 the Nuna team scored a hat-trick with their third victory in a row; their Nuna 3 won with a record average speed of 102.75 km/h (63.85 mph). Aurora finished in second place followed by the University of Michigan in third.

    In 2007 the Dutch Nuon Solar team scored their fourth successive victory with Nuna4 in the challenge class averaging 90.07 km/h (55.97 mph) under the new rules, while the Ashiya team with their car Tiga won the race in the adventure class under the old rules with an average speed of 93.53 km/h (58.12 mph).

    But it makes sense, with the average Dutch weather our solar tech has to be really good!

      On another note, I have an idea as to why electric cars (even ridiculously fast ones like the tesla) don't get the "hotness" factor that other race cars get - they don't make loud noise. I think the visceral reaction to a loud muffler is what draws the "speed" emotion from folks.

      Yes. The internal combustion engine generates a lot of power. Googling around I read about 15kW sustained power (to move an "average" US car at 50 MPH). That would be 45 to 100 square meters of solar cell (15% to 33% efficiency solar cells) to get equivalent power from solar. So no matter what, you're speaking of lower power production than an internal combustion engine. I don't see that the general public is going to be interested in that.

However, the Dutch team from the TU Delft (the Nuna, that won the last 4 WSC in Australia) have had such success and press coverage here in Holland that that too is declining because now it's almost become expected for them to win.

      I was part of the SAE Aero challenge in '99, our team's plane suffered damage during shipping and the WMU guys were the only ones nice enough to even offer help. WMU has my vote, even with a broken car!
  • I've always wanted to see a solar powered articulated lorry with battery intermediate systems. If you are going to accept that with solar panels as the only energy input the vehicle will never be ready to use at any time, you might as well build something big that can carry several tonnes of batteries and let you make a respectable length of journey before having to sit in the sun for a month to recharge.

    Moose versus Solar Car would not harm the moose, but it would be unlikely the car would roll again. What sort of technology is being employed for the very serious issue of possible Moose Damage inflicted onto a solar car during a race?

    those truck drivers drive like hell on US-75 so be careful!!! stay in the right-hand lane whenever possible and the truckers will naturally pass in the left lane (the hammer lane)

    I live 60 miles from McAlester i may just drive to BigMac just to wave from the side of the road, i wish you all lots of good luck...
    • speaking of trucks. Dont they got a lot of space on the trailers to load up on solar cells! Would a trailer covered completely with pv cells be enough juice to run the truck? This could make the shipping system in the country cheaper in the long run?

        Assuming 100% coverage of the top surface of a trailer 102 inches wide and 28.5 feet long, the solar power available would be (2.6 m)*(8.7 m)*(1400 W/m^2) = 31.67 kW = 42.5 horsepower. This is even before considering the fact that the best solar cells are only

        The power wouldn't be sufficient to power the truck directly, but could help with charging the battery.

    Wow, it was quite a long time ago, but latches I sell, normally used on carbon fiber race hoods I manufacture were donated to the OSU team to latch the top and bottom halves of the car together.

    If you are curious, it's these:

    I just got a msg on the 26th that they were heading for their first race, but forgot to follow up on it... I see it's on it's way... but they may have had battery problems :(

    here's the OSU blog with up to date info:

    • Wow! I saw those while I was out at the race and I swore I would track them down on the web to try and use on our team's solar car. I'm totally bowled over that I should chance over them on slashdot of all places. You wouldn't happen to want to donate a few of those to the Stanford team too, would you?
  • Whats crazy is that the 2nd place team as of this writing is Principia College, a school of only 500 students and no engineering dept or major. If they pull out a win it could go down as one of the biggest upsets in college sports(?) history. Of course they would need to beat a team that has millions in funding and its own satellite for weather data and a team of meteorologists.
  • I heard from an MIT friend this past weekend that they had to drop out because Michelin yanked support for using their tires at the last minute, and that was going to knock a few other schools out of the race as well.

    • by cbc1920 (730236)

      For some reason, Michigan is still able to race on Michelin tires. The MIT team has, as far as I know, pulled out of solar racing completely.

  • Where the hell is Carnegie-Mellon [cmu.edu]? How can you even think about having a car race like this without inviting them?!?! Or maybe they didn't invite them because they wanted the other teams to actually have a chance? ;-)
    • by Hal-9001 (43188)

      I think you're somehow confusing the North American Solar Challenge (which Carnegie Mellon has never entered, to my knowledge) with the DARPA Grand Challenges [wikipedia.org], where Carnegie Mellon has usually been the favorite and has traditionally done quite well (an upset by Stanford in 2005 notwithstanding). They are very different races requiring different expertise, although it would be interesting to apply machine learning techniques to solar racing strategy.

    i'm find it fascinating that the rules state that the cars are only allowed to run on global thermal energy - which includes wind, EXCEPT for any power stored in the batteries at the beginning of day one.

    if i read this correctly, the team with the most efficient batteries (and/or greatest battery capacity) has a tremendous advantage.

    an even more interesting race would start with all cars at a zero-charge, i think.

    • by aXi (6533)

      How right you are, one full day's solar power should be enough to fully charge any discharged battery.

    • by Gertlex (722812)

      Battery capacity is limited... so indeed efficiency of electrical systems is something to strive for.

      Efficiency of the solar cells, however, is not limited. The more money, the better you can get.

  • using only the sun for fuel.

    Um, besides the Sun our only other fuel sources are nuclear and geothermal, both of which, for the most part, come from the star (or stars) that preceded the Sun.

    In case you're wanting to argue with me that gasoline, coal, natural gas, etc. are also other fuel sources: Fossil fuels come from plants who got their energy from the sun. Wind and water power are also powered by the Sun.

    </thinking with the anal retentive geek>

    • Fossil fuels come from plants who got their energy from the sun. Wind and water power are also powered by the Sun.

      Right on the spot. We need to understand that solar energy is not some kind of exotic energy for funny cars. It is pretty much the only energy we have, compared to which all other forms of energy (nuclear, geothermal) pale into insignificance.

      Using fossil fuels is actually a fairly inefficient form of using solar energy. It took millions of years to collect that energy and transform it into the fossil fuels as which it is now stored. Compare that to a few hours for recharging a battery from PV cells :-)

  • I thought both the start and the destination was somewhat ironic for this type (solar) race. It wasn't mentioned in the article why these two places were chosen, perhaps because they get a lot of sun.

    However when I think of Texas I think big oil, and when I think of Alberta I also think of big oil. They are probably two of the largest producers of oil (land based) in North America. Perhaps this figured into the decision as to the selection of the cities. Anyway I hope the irony was not lost on them.

  • Solar power-- and presumably, gravity. Unless they've found a way to cancel that out, to make the competition more fair. In which case, keep your silly solar powered car. I want a gravity canceller.
