World Solar Challenge pits high school, university, and corporate teams against each other in a race across Australia's Outback, from Darwin to Adelaide." Mdog supplies some more (ahem) non-partisan information about the race below.

"My Alma Mater's team (which took second in the American Solar Challenge...go UMR!) is looking to take sweet revenge on the evil (*g*) that is the U-Michigan Solar Car team (which won ASC.) Some other North American heavyweights will be Queen's University and U-Waterloo from the frigid north. I'll defer to Ozzies post links to their favoUrite college teams, which, along with the Japanese teams, are often very good. Lastly, watch out for team Solar Motions; out for blood after major technical problems two years ago. Their array is worth...how should I put this...a lot :)

I went two years ago, and this year I'll just be looking forward to this article getting posted on /. *sigh* Good luck and good sun to all the teams. No worries!"

    But what I would like to see would be a competition for fuel-cell based vehicles. Fuel Cells are obviously the way forward for the future, so why is no attention paid to them ?

    Could it be that the big oil interests have no interest in a cheap efficient environmentally friendly source of power ?

    You have to wonder sometimes when good technology is ignored, is there some sort of hidden oil-company aganda ?

    • As I read it, fuel cell technology (for cars) is still kinda immature even for experimental race vehicles.

      Besides which, everything in these solar vehicles, including the aerodynamics, efficient electric motors, the power management, and so on, is directly applicable to future fuel cell vehicles anyway.

    • Actually a lot of the technology used in the WSC, such as wheel motors, and battery technology, are very well applicable to other vehicles.

      I know that Aurora's entrant vehicle in the '99 WSC (which won) had a wheel motor of efficiency 98.4%! And that wasn't even the most efficient wheel.

      And this got labelled informative? Sheesh.

      Here [solarbuzz.com] you can see a list of solar cell manufacturers - at least two oil companies (BP and Shell) are on it.

      Here [eurec.be] is a view from the EU about the future of big business in photovoltaics.

      Here [shell.com] is an account of Shell's involvement in Fuel Cells and Hydrogen power in general.

      Here [qld.gov.au] is an account of some of Shell's involvement with biomass power generation.

      Here [bbc.co.uk] is an overview.

      Still, no doubt these will be dismissed with a "Yes, but apart from the solar cells, the fuel cells, the biomass research, the wind energy, and forestry, what have the oil companies ever done for renewable energy?".

        Sorry but oil companies are not the people pushing fuel cell technology. Try DaimlerChrysler [futureenergies.com], General Motors [futureenergies.com], Toyota [futureenergies.com], Nissan [futureenergies.com], Ford [futureenergies.com], amongst others. You will find most of the oil companies 'fuel cell research' are actually 'joint ventures' with other large companies where they encourage the use of gasoline as a fuel cell source instead of alternatives such as hydrogen. And though some of the oil companies do some solar research, a lot of their technology is based on buying up small independant solar firms. Oil companies have nothing *against* alternative energy but their motivation is profit at any price. Thanks to independant work being done all over the world, and plenty of governments subsidy, green energy is now being eyed by oil companies as a new cost-effective area in which they can become a monopoly.

      There are competitions involving fuel cells, including Future Truck [futureenergies.com] and karting [futureenergies.com]. Fuel Cells take a lot of R&D but when their price begins to decline we will see a lot of independant parties begin to become creative with what can be done... then we will see an increase in the number of races.

      Could it be that the big oil interests have no interest in a cheap efficient environmentally friendly source of power ?

      The big oil interests certainly have an interest in green energy... if it will make them money. Look at BP buying up all the small solar companies and cornering the market in solar cells.

      You have to wonder sometimes when good technology is ignored, is there some sort of hidden oil-company aganda ?

      Fuel cell technology is certainly not being ignored, it has massive momentum behind it. Most of this is from the car companies, who don't really care what goes into the engine (oil, hydrogen, etc) as long as people buy their cars. If fuel cell technology fails to take off it will be because of public apathy in supporting it, prefering to pay slightly less for old established petrol based polluting machines instead of the new and inevitably to begin with more expensive green option.

      Phillip.

      • Because it gets rid of the ability by the world's largest cartel to dicate the price of the product they sell.

        Medium-size oil, without the massive R&D budgets of big oil but lacking the nimbleness of startups, would likely be in big trouble if we shifted to hydrogen fuel cells.

      • the motivation behind the oil companies to invest in alternate fuel technology is two fold.

        The first is that by investing in (read buying up) new fuel innovations they can squash them, prevent them from reaching the global market. It is easy to see that they gain by doing this.

        The second is that the are realists. They acknowledge that the time of oil as a fuel will eventually come to an end, or slow. To prevent themselves slowly collapsing when this occurs they need to diversify, one easy way to do this is into the alternate fuel sector. Its obvious that as their traditional market declines this new area will pack up, and with a collection of alternate fuel devices and concepts (from motivation 1) they are in a strong position in this market.

      This race has been around since the late 80's, before fuel cells were even viable as an energy source. Nowadays, this race exists to promote creativity and thinking for team and to advance the technology of alternative-fuel vehicles. How much fuel do you think you'd save if your car was super-strong and only weighed 800 lbs.?

      Plus, fuel cells produce electricity. If more efficient ways are created of using that electricity, so much the better. I've had a part in a few American-side solar races, and usually, the oil companies want nothing to do with them, since it does have the potential of affecting their bottom line. The poster from Sunrayce '93 was a picture of a solar car driving right by a gas station. To bad the humor was lost on most..
    • One of the significant aspects of solar car racing is that you're doing it all on a shoestring power budget. These things drive at highway speed using roughly the power of a hair dryer. This requires nice light batteries, efficient motors, and clever aerodynamic and mechanical design. When you're redefining the state of the art, something useful usually comes out of it. Solar car races are also often a proving ground for new technologies that teams are eager to give a try and corporations are eager to get real-world performance data on.

      Fuel Cells may be a great technology for normal automobiles, but the cool thing about this race is that these things are quite far removed from normal automobiles.
    • Actually Fuel Cell racing is now finally reaching its infancy. Recently, the American Solar Challenge had its post race debriefing and it was decided that fuel cell technology should be looked into for future Solar Rayces. Talk at that time was that fuel cells would have an unfair advantage over Solar Vehicles, so it was considered that they be rayced along with the Solar Cars in the ASC, but as a separate class of raycer.

      Contrary to popular belief the leaders in fuel cell technology are actually car companies (like Ford and Chevy). They realize the problems that are going to be facing not only us, but them in the future. That is another reason that several car companies support solar raycing.

      Just my opinion.

  • I wonder if a solar car is ever going to be a reality, after all, the potential market includes southern USA and a lot of developing and third-world countries. With OPEC controlling oil prices so it doesn't loose control of the energy market by making alternative energies cheap enough, I doubt that we'll ever see a solar power aided car (fueled by solar+gas) anytime in the next 30 years.

    OTOH, I wonder if a plane wouldn't be an interesting use. After all they have a lot of area on top, they can fly over clouds, and the industry is always looking for ways to cut costs.

    • I don't think solar cars will be a reality for the moment.. The cars themselves are just not able to be converted to commercial use so easily (most of the cars are very expensive, not exactly "safe", and cramped more than anything else).

      But the technology developed as a result of the cars, is very applicable to everyday life. Even the research that goes into the aerodynamics, for example, is having an impact on commercial vehicles..

      I happen to be a member of the Yale Solar Car team - Team Lux. So needless to say I've studied solar cars quite a bit. So...

      NO: Solar cars today are an experiment in engineering, not a solution to your everyday commuting needs. We can get relatively high speeds and drive all day, but the cars are very wide and long, flat, only hold one medium-to-small person (barely) and are limited by the environment.

      YES: Any electric car could easily be supplemented by the addition of a high efficiency array. It wouldn't provide enough power to drive the car all day like we do with the current crop of cars, but since most people only drive their cars about 2-4 hours a day it could help a lot, and could be a real lifesaver if you ran out of power. OTOH, even a well designed commuter car is going to be much heavier than our solar cars and have much less array area. What would make the most sense is for all carports to have arrays on top that could store and transfer energy to the cars parked under them.

      MAYBE: I don't know that electrical cars or fuel cells are the (near) future. Chemically propelled cars can potentially be much simpler and more efficient, since they aren't losing power through the extra electrical storage/transformation. And you can make fuel using solar power (you already were with the fuel cells). And until efficiency actually matters and the big-ass SUVs get off the road, it just won't be safe for extra-lightweight cars.

      BTW, the plane thing has already been done with the Helios project. And you're right, it has a lot of potential.
      • I happen to be a member of the Yale Solar Car team - Team Lux. So needless to say I've studied solar cars quite a bit. So...

        WHat kind of batteries tend to get used?
        I'm assuming that you want the most storage for the least weight (polymer batteries?) vs limited budget (cheap-ass lead-acid...)

        Chemically propelled cars can potentially be much simpler and more efficient, since they aren't losing power through the extra electrical storage/transformation

        I do a lot of solar projects (mostly on a miniature scale, won a few small solar competitions, etc), and sometimes keep an eye on some commerical electric car developements, and my understanding is that the opposite is true - anything with a combustion engine suffers from hundreds of moving, wearing parts, relies on kludgey, expensive additional systems (clutch, etc), dumps all it's energy every time you hit the brakes - then wastes fuel getting back up to speed again. (Which in a city commute might mean you're spending ten times the energy actually needed. Hence hybrids getting up to four times the mileage).
        Electric engines are cheaper to make, last longer, more reliable, often involve no moving parts bar the shaft itself, gruntier even when running on significantly less energy, etc etc.

        But until an electricity storage system gets to the point where it hold even a signficant fraction of the energy that petrol does, you're right.

        BTW - I'd be interested to know how many orders of magnitude less energy these solar cars run on compared to a combustion car - can you give us an idea of what a typical solar-racer solar panel output is?
        • Our team currently uses the best lead-acid batteries available. They're expensive, but much less so than Lithium Ions, which is what most teams are moving to. But of course they're very heavy. Budget does make a big difference in the kind of car you can build, with regards to practically every component. You may have heard that the University of Michigan won the recent american solar challenge this past summer - what you probably didn't hear is that they have huge amounts of resources both within and outside their school, and a monstrously large budget. Their car cost over a $1,000,000 for components alone. In contrast our current car is worth about $250,000.

          When I talk about chemical engines, I'm talking mostly about potential efficiency. There are some pretty amazing engine designs out there - there was a recent article about a rotary engine that only had one moving part besides the shaft and valves and required no lubrication.

          Most teams use the same type of engine, which is built into one of the wheels. It's a lot louder than you would expect (makes this wierd popping noise) but gets better than 90% efficiency. OTOH the power range it can provide is limited.

          I'm not sure about orders of magnitude, but I can tell you our car runs on about as much power as a hairdryer.
    • When solar power finally becomes a common source of power, the arrays won't be attached to the cars. The Better wasy to do this is to have a relatively large, high efficency array mounted on the roof of your garage or something, and then just pjug your car in at night. This is not currently feasible due to limitations of the battery technology. When things such as high density lithium polymers reach production, this concept becomes more likely. But the energy storage medium doesn't have to be a battery. It is just as easy to use a fuel cell or a capacitor to store power. All these technologies exist, but are not common or far enough along in developement to be all that practical for daily usage.
      • Why can't the arrays be installed in the surface of the roadway? They could transfer their energy to any compatible car that passes over them....

        Plus (here in the USA anyway) there is a LOT of road surface available which is currently only used to hold up vehicles.

  • Personally, I think that solar power, while a great power source, should be considered a secondary form of power. An electric car that could be run in the daytime by solar panels would be incredibly fuel-efficient.

    • Most of the "power" for the solar cars actually comes from the batteries.. Queen's University's car, for example, in the '99 WSC could run at 70kph on the array alone, but at 120kph with the battery power as well.

      So, yeah, they practically are a secondary form of power, but still.. The technology used there, goes on to more practical applications.

  • I am on the University of Virginia solar car team, and I remember some of these teams from the American Solar Challenge this summer. I have a few comments on the teams:

    Arizona University:

    If memory serves, these are the guys whose car spun out during qualifiers and flew through the air, tearing off the suspension when it landed. When I saw it happen, I thought they were finished. They had it up and running for the race and did quite well, much better than we did.

    Futura:

    I see they've withdrawn. They had some problems during the ASC. I can't really say what, but they were very far back in the pack despite what should have been a very high-performing solar array.

    Kansas State University:

    It's sad to see these guys are out of it, because we worked with them during the ASC getting our car and their car to pass scrutineering.

    Queens University:

    Wow. That car is nice. That's all I can say.

    South Bank University:

    These guys did pretty well in the ASC. They had an accident during the race and severely damaged their body, but duct tape kept them going and competitive.

    University of Michigan:

    They rebuilt their car 17 days before the ASC because it was destroyed during testing. They have a GaAs solar array, Lithium Ion or Lithium Polymer batteries, a very sleek design, and 4-wheel steering. Apparently when they redid the 4-wheel steering, they replaced the mechanical linkage with an electronic control. It's the most advanced solar car I've ever seen.

    University of Missouri-Rolla:

    These guys nearly won the ASC despite only having a 14% efficient array. For reference, some teams had up to 26% efficient arrays. Their car is incredibly light and efficient. Nobody in the race was even close to them on mechanical efficiency.

    University of Toronto:

    Good car. Nothing much comes to mind. Didn't see them much because they stayed ahead of us.

    University of Waterloo:

    Yet another very good car. They did a very good job of integrating the wheel farings with the body to keep aerodynamic drag very low.

    That's about all I have to say about that. If you want to see how the ASC went, check out their website at http://www.formulasun.org/asc/ [formulasun.org].
    • Speaking as a Queen's student, I must say - thanks. :-) I've examined our car, and briefly considered being a part of the team responsible for designing our 'next' car.

      If you check out the webpage:
      http://solarcar.queensu.ca/ you'll see Mirage -- this guy's right -- isn't it nice?

      Interesting differences between 'our' car and others is that ours is entirely student-designed. The only review that it gets is for safety by a couple of mech.eng profs here, and the occasional consultation with the companies the guys (and gals!) buy their equipment from.

      According to things I've read, the UMich team gets a fair bit of help from some industry people in the area -- that's their way, and it certainly has improved their car. I personally admire teams like Waterloo/us/etc. who manage to design their car entirely on their own. It's two years of work and literally over a million dollars to build these things -- do you think it's worth it?

      Anyway, 'Go Queen's!'. Queen's College colours we are wearing once again,

The wheel wells were designed by a first-year Computer Science student (myself). Of course, we came in 24th, so I will refrain from bragging about how much better we are than the teams that got outside assistance that kicked our asses.

  • How large a solar array do you think would be needed to power a small air-conditing unit, sufficient to keep 2-3 cubic metres of air cool on a hot day?

    It's a project I'd love to see done, but i don't have anything approaching the electrical know-how to do it myself. What I'd like is a something to keep my car cool on a hot day, and if it can be powered by solar power, then it's plausible. The hotter the day, the more light you have for the photovoltaics - but is it enough?
    • Rough rule of thumb is that the sun output about 1kW/sq. meter. Based on that, you can figure out how big an array you'd need, with a given efficiency.

      For example, a 4x8 meter array, with 15% cells, outputs about 4*8*0.15*1 = 1.2kW power.

      Now, figure out how much power your cooler needs, and design from there.

    I'm a member of the Principia College Team (7th ASC) and I'm leaving for WSC tommorrow. Our team is just scouting this race, so hopefully i'll have time to post a thing two to /.
  • Go Waterloo! UoW is where it's at.. u guys down there kick some ass!
  • One of the top local entrants (and my Uni's entrants) have their page at:

    They came 2nd in the 2001 sunrace from Sydney to Adelaide. I get to see their car drive past my office some days... :).
  • I worked on a car in the first World Solar Challenge. In fact, I was working/studying at the Northern Territory University (NTU) in Darwin Australia at the time. That's where the race starts, so you can imagine as the 'local boys', we had a good deal of support from the crowd at the starting line!

    As has been pointed out elsewhere, this isn't really about making a solar powered commuting vehical. It's worth noting how much additional benefits came out of the fundamental research going into the entries in the race. A GM team built a car that stormed in to win the first race, and little wonder since they had millions of dollars to play with and bought the entire world's terrestrial supply of galium arsenide solar cells at the time (the rest being bound for space).

    A lot of fundamental research was done on improving the efficiency of electric motors, their drive electronics and simulations as to the most efficient way to drive these vehicals. Hell, even the telemetry to the support vehical was something pretty new for the time!

    There ought to be many more of these sort of worldwide research challenges. Especially in areas that really will become important soon such as fuel cells as others have pointed out. I see now they have difference classes in this race for battery as it is - little wonder, my god we would have died for Lithium Ion batteries in 1987!

    It's just a bit of a shame that the organisation of the race itself is fairly poor and that the web sites get dumped with each new event and hence sponsor. It could have made for a wonderful web site with all that archive material.

    Just as well NTU has done a fab site [octa4.net.au] of their own.

    P.S. You can't imagine my elation at seeing NTU's car come second in the 2000 race, not to mention claiming the world record for fastest long distance solar car!
