taps by african-americans community leaders say it's likely to be the result of high unemployment and tough competition for jobs. while have more of those stories to the top of the but in the meantime we'll take a look at technology update where we explore the latest and most innovative scientific advances that's next to stay with us. hello and welcome to technology update this month we're here at the world class racetrack hockenheim ring in germany where students from russia and around the globe have come to put their self-made to the test less than two weeks before formula student germany kicked off at hockenheim brain and played host to the country's biggest race formula one's german grand prix tens of thousands of fans packed the grandstands parking lots in campgrounds to watch the world's best racers

chase the checkered flag despite a controversy over the communication between two for a team mates spaniard fernando alonso claimed the championship and shower. before its modern day make over hockenheim has been a hub of german racing since the first track was built in one thousand and thirty two formula one races in a larger force kilometer passes all the stands with their fans clear the campground place temporary home to the formula student teams the students race on the smaller specially designed for sun the infield when steve gets going they'll housing tune up their cars in the same pits as the burners from big time circus formula studio organizers set the stage inside on tuesday to camp grounds just outside are starting to fill up but instead of the tailgaters and vacationers cramming in for formula one trucks full of tools and stashes of space in from all over europe. and of course each team's prize positions there's still visioneer race cars on the

ground up to divest their university could offer it disappears competition the teams in the moscow state technical university mommy managed to make it to town before many of the german school and is quickly working to reconstruct and fine tune their automobile after its long trek across the continent everything's been carefully calculated in advance and at worst wasted if you can't come to get. on the track. of the engineers had changed about their design to improve over last year the main target has been shedding precious pounds from the car. to achieve this they build the frame out of twenty to fifty kilograms over two thousand and nine in the engine they keep the same honda c.b.r. six hundred. four cylinder switched to a lighter single cylinder engine failed their cost efficiency evaluation. intake and exhaust systems from scratch and incorporated in additional control units to optimize fuel combustion giving them a boost from forty to seventy five horsepower braking system uses the same pads and

cylinders switch to discs from honda to home made to be more economical they managed. by changing to new wheel and shifting. cooling problem they encountered in two thousand and nine. this year's car came out twenty five kilograms lighter roughly three fourths as expensive and nearly twice as powerful. this scene is heating up. the young engineers from some seventy five institutions in eighteen countries on four continents are every bit as busy mingling in scoping out the competition as they are setting up their equipment and running last minute trips to see if their cars are ready for initial inspection. or somebody. come from. and how do you like it. and from that. you. see this. stuff comes.

right and that's what's new about the car the. moment. it's not. says it's all right good luck. good result a. defining champions for stuttgart are busy telling their sausages where is your car well i'm still waiting for the car of me made some pacing today this is why we have to put in cotton frog in. a way what do you like your chances for another win this year you know i'm not bad because we're. going to cause it's national i don't we've made a lot of problems on the engine the fuel consumption. and suspension makes the race better threat so close a. team an awful long way why did you choose to compete form

a student in germany well as we've seen from a student from a ball we've really seen the german teams and your team seems pretty much over the cars awful awful and so i asked why we want to bring our car to germany to compete and see our car compares with their cars houses they can hold up what do you think it's going to do i think is going to do very well we have different style than some of the german cars so it's a different approach we've taken us you know so on there i can't imagine that we converted to any five fuel injected and i also turbo charge makes eighty two horsepower and a little over fifty four pounds of torque so. awesome and good luck make the same thing. you guys made here from moscow how do you feel going into the test tomorrow . grades and waiting some more test and now we do in some final preparation results are some lake chic and sponsors seekers of course who are diets and snowy

german so it's just hopefully they'll get their fill and get a few hours of sleep but it's not like you guys just started work on this is a long time in the make a of course is three years' experience in the formula soon germany will spend you know one car each year and these current one able to is the best yet. resulting. back in october of two thousand and nine. interested in. a few years of collective experience to. within a few weeks. each. head engineer had a concept for their two thousand and ten model only to beginning almost five months

before they for the first time could only be reached through months of projections calculations presentations to sponsors and painstaking assembly in addition to their academic work they also had to study up on the rules of the game for germany early in two thousand and ten of well over one hundred applicants confirmed they'd be among the teams take time and they were well on their way to building a successful. team. people. very good. because you have all the. money. so. do it in the back. so you need this. skills if you get all this stuff.

day morning the teams are learning how they stack up against. tests of their engineering. came in the form of a quiz to determine the teams would enter the. crucial because he. can't rack up points in the other tests until you've passed scrutiny fortunately the team from miami had done their homework and woke up to a pleasant surprise on the week's first leaderboard. test result indeed we didn't expect it so all the best rushing team today. previously the scrutineer in order was sort of flattery but it was a sort of contest and so actual contests and the first teams who pass the test. they have a chance to be first it's continuing armed with a bit more confidence from that initial result mummy joins the rush to transfer their car from the camp to the pit stops their home and workshop for the remainder

of the week's action in the same facilities where the formula one squad serviced their racers days earlier they need to set up a rapid response station to keep their car running at its best and adapt to any issues that might pop up in the course of testing the cougars are close with the formula student pits increasing the sense of both competition and collaboration. the student teams have already started bringing their cars into the pits here one of the russian squads from us girls my d. is still having trouble getting the hockenheim last we heard from them they were stuck in a customs crossing somewhere in the middle of their track across europe monday is short for moscow automobiling road institute one of the soviet union and now russia's top technical universities with a history of nearly eighty years and five years of experience in formula students like their colleagues from across town in mommy they too have been hard at work all academic year on their two thousand and ten nicknamed indigo from their first design adaptation since september two thousand and nine they were several months to

the drawing boards before the frames started coming together in december then it was measurements assembly and reassembly on repeat until everything checked out their car may be unique for its use of a yamaha p.c. fifty snowmobile engine perhaps an innovation from the depths of an unusually cold winter even by russians stay. some help along the way from a venerated mighty old head long time soviet and russian racer. in his nearly half century long racing career and for decades in monday's laboratory of high speed automobiles he spent most of his time behind the wheel or under the hood of many cars famously adapting several in this series of so-called this erasers. i think the first car i had was the eighteenth model that i drove the nineteenth and then my mechanic and i made three new. they went fully our own design with a modification of the twenty first model to perform

a will. the main things we changed with the. aerodynamic components. a new frame enhanced road stability and the aerodynamic components helped decrease the wind drag. time i raced the improved i was in. and then driving experience was completely different it was fabulous. smooth i would have thought i was on rails. you must have engineering experience to do that and as for the understructure and wheels we've got very talented smart people and that ensures good results looking with bryce creative students like the ones involved in formula student that's really a great pleasure. to pieces started coming together for my d. this spring they use the same steel twenty is money for their frame also commenced it was delighted most cost efficient material. engine required some homemade

adaptations to their intake in oil systems but it stood to their tests come summer time they decided that simpler was better and certainly more economical on the whole they wanted a car that would be easy to drive by novices in connoisseurs alike as well as being relatively simple to service. students germany isn't the only guest in hockenheim ring during the week. and the stadium is also filling up with fans for another event and for it to try and track. these students are busy putting their cars to hold summit test racers and race fans from all over germany and beyond and gathered to test their own engines the famous train. and fixed summer talking public race days give the two and doozy of a chance to flex their muscle cars the rubber on their motorbike into today drag racing extravaganza it's about showing off your handiwork both in the lights and on the track the clientele is a bit less clean cut to the engineering students who wander over to take a peek but they're no less obsessed with getting every ounce of performance out of

their vehicles and while the tires screeching smoke billowing high jinks are mostly for show and the drag track is a far cry from formula style lapsed some of the same mechanical savvy is on display . at the very least in the formula student teams could build a race car out of steel bores motorbike ancients and spare parts to be quick studies in team covering with and rebuilding slick mustangs. let's get back over to the scrutiny hearing to see how the teams are fairing to approval in this stage just the race team's holy grail since it's the lone gateway to purchase a patient in all the events and tests where points are one but that approval has not come easy and only four teams from the entire field have gotten the green light on their first this scrutineers or scouring every last detail to ensure safety and test the engineers knowledge compliance with formula student regulations is the

main goal but it's equally important to be able to think on the spot and respond to criticism of their students you're going to be pretty prepared basically for their future life and work and that hurts your so i have to do what i do get the fireman's from the customer and you have to learn according to that. and that's basically what they learn about it so they have the rules they have to see. and also have to like think about the rules because saw not everything is written like the white but some things are logical and so you have to go this way and that i think is a good preparation for future american life screwed nearing certainly has many to scratching their heads for quick solutions trying to fix problems on the fly in the pitch must go as monday is among those with a long list of issues closest to woods the status of your team at this point. we've gone through the technical examinations twice they discovered several major violations the first time but we managed to get rid of them over the course of the night that was yesterday they had

a problem with the cockpit templates we have to use for ensuring that the cockpit opening and the cockpit itself is big enough for every driver there were some problems with the side walls of the cockpit so they fix that and all the templates are fine and. the major problem is resolved because. we have identified some remaining minor flaws as a result of the test they're not hard to fix but it's difficult in our case as we don't have the required spare parts we simply won't have enough time to fix them as today's the last day of the technical examination and tomorrow is already a state of. monday's russian rival just passed through nearing in moved on to other events. the team from ami seems to have run into some technical issues going into the break test let's see what their problems are. new stories who

would turn the switch the whole system that we went to costs the rink tasks but there was a problem with the engine just due to the miss stone design salacious case was broken we borrowed a spam from another team and we're installing it right now so the question so hope we can get it running was actually the spirit all the fullness didn't. open to its help it's never. really serious to win but in the pits very very helpful. with a friendly offer of the needed money still has to scramble to get their car up and running to take their allotted turn in the brake test fortunately they've isolated the problem and with the. right alongside the track. so the starter situation is sold but now the brakes aren't locking all four wheels it once and the judge just can't let this kind of performance. we do see issue more

complex than the last decides to pull back to the pit stops to find the right pieces to solve the puzzle. and you. are looking for the problem fortunately some of the student judges in the pits with useful suggestions. and so what's happening is that. he's on one side and nothing. so when you bring the one which is no mood it's no contest because there's no friction. suits first and suspension from. these types of issues did mommy worked long and hard back home to foresee before packing the car off to germany they put it through hours of dynamic testing laboratory in race track facilities in and around the russian capital they tested the engine for overall power acceleration in fuel efficiency they tested the suspension to make sure weight was distributing properly and the car was handling it to do it and of

course they checked their brakes to make sure they responded to reasonable pressure and didn't exceed acceptable temperatures fortunately they also learned how to check for an quickly counteract problems with all of their car systems a skill that would come in handy in hockenheim after so many tries determined to see the checkered. ag before waving the white one in with even the judges rooting on the enthusiastic russian students they finally did. it is are you feeling just. if we spend the whole day in the static testing room. the noise tests the noise test in the break test of course. because some time in nine attempts to finally get those breaks locks and policy. guys were all very happy because we're now ready for dynamic tests and the insurance rates. and we can brazing insurance rates gave us the most points but says the main thing ongoing

will have to do is make it to the finish line but the other person or engineers can take a breather and yet they have done their job the col is running and he's running wells doing much in the u.s. now up to one tribe is to show what they can do that on the racetrack. usually a big time race track like hockenheim ring falls silent at night but in this pit the cars are still coming and going while the other teams sweep that's because formula student germany has had it in the electric car competition to the electrics to get first shot at the formula student in durance track for the occasion giving us noise regulations generally been late races but these cars are so quiet nobody's complaining sixteen teams rose to the challenge of producing a car in this inaugural event including many universities also involved in the combustion competition team mind moving to celebrate claiming the most points on saturday's race but will have to wait till sunday's aboard ceremony to see if it's

enough for the electric overall crowd. to build electric call is a new togs for the students because elects a. stand in future and now we are very happy that we got so many teams. had to do with this call so there's shells ability elsa's jewels. to adept. sunday marks the culmination of formula student germany combustion car insurance race despite the late finish from last night's electrics already filling in for the early morning start. also joined by press and big name sponsors who've come to see these top young engineers. german powerhouses like. mercedes and b.m.w. . catchers for the event they say they made cars on display here formula student is ideal training for staffing their own design teams of the future. concerned about the extra attention the race teams know this event could well be

for all the marbles and they're focused on making sure their cars stand to the test . come a long way to cheer on their sides. around the track they're getting it right. before their start times the teams are lining up detention of the big day is because the humid hockenheim air out of the box early after several of the front of them in the running order simply couldn't start when their flag went up conditions are tough judges have decided not to allow the teams to change to rain tires despite scattered and occasionally strong showers still mommy is pushing the limits of their traction determined to be the first russian team to complete this event. the race runs twenty eight laps around the course for a total distance of twenty two kilometers between the points for finishing fastest

and for highest fuel efficiency there are over four hundred riding on the endurance competition nearly half of the winning total is mummy remembers from two thousand and nine where they came up to light short of the finish no points for partial completion. well the results i respect i would say were happy with the results because we've made it to the finish line which means. teams did not their cars broke down along the way our task was to make a car and take it to the finish line mommy is excellent it's very close. we have here from the let's go. to a call to. call so i think a very good development. is the deed goes on faster and faster teams are taking the track but the weather is not necessarily playing along dumping more obstacles on to the already tricky raceway caution flag school a periodic lead but many are simply struggling to find traction the spin off the

course or cone straight from sloppy turning the driver in their team a time penalty some course are experiencing more severe damage than the occasional coon though and it looks like fewer than half of all cars will follow me to the finish line. the real burners secured the later start times thanks to their superior performance in the previous tests in dynamic events and the top seventeen teams all finished the course in under twenty minutes for an average of less than sixty seconds a lap dutch team delft the university of michigan in the middle east to reno took the top three spots ending their hard working week on a high note i think very important to take home this experience. we have money and we go. to the people coming up with the last laps completed in the tanks checked for fuel efficiency the formula student cars have done all they could while the teams

hustled their vehicles and equipment to trailers and clear out the pits is handshakes among teammates some new friends and rumors about who get the most nods from the judges with everybody cleared out and a bit freshen up we climb atop the pits to hear who's taking home one trophy. you can see the word serial movies where the we will come off or at least. where the glasses raise up their speedsters having spoken for themselves now it's time to celebrate it was very good so very nice things to you you are a great spirit great if you say so loud. you became a little tiny does it seem that we now know what mistakes we've made and we're ready to move on and correct those mistakes it will get through every stage of the competition and improve our schools next year she will be stronger and will work in attracting sponsors and others to go even further to. the royal engineers here really engine is and we're celebrating a victory it might be

a small things to us but it's still a big training but not by b. at the the green team from uni stuttgart grabbed the electric overall crown but their classmates couldn't pull off a combustion repeat teams from move by into a shoot took prizes for cost analysis running snail from ember germany scored the most innovative power train any rain ians from is behind were named best new comers all aspects of design presentation and performance are up for consideration in the end the team that ran fast to send most fuel efficient racked up the most points from the technical university of delft in the netherlands. it's a common feeling winning a crisis. doesn't get any better. finally everybody gets a chance to kick back and enjoy their successes winners or losers but when they make it back to their hometowns around the world it won't be long before their meeting to sign next year's car that's all from formula student join us for more next month on technology update. and try to.
