The name is strange, and the material seems to possess otherworldly strength, but it's all very serious. Buckypaper is a new material composed of carbon nanotubes that promises to revolutionize composite materials. Stacking sheets of buckypaper together nets a material that's 500 times stronger than steel, yet 10 times lighter. Florida State University is working on making the material inexpensive to produce in large batches of ultra-strong sheets, and the possible applications are wide and varied. Airplanes, automobiles, household items, the possibilities are endless, though we'd be most interested to see buckypaper mature to the point where it can comprise a monocoque shell for an automobile. There are challenges to getting the nanotubes to arrange properly for high strength, and bonding something with such surface smoothness is also difficult, but the promise of a new wonder-material has built a lot of excitement and could one day replace carbon fiber as the exotic material of choice to both lighten and strengthen our cars at the same time.
In the land of mergers and acquisitions, there are takeovers, there are hostile takeovers, and then there are I'm Gonna Git You Sucka No Matter What takeovers. Porsche's increasingly acrimonious battle to swallow VW is becoming that third option, and the brawl might threaten the short term plans of Porsche, VW and Audi. Porsche wants access to Audi engines and electronics, but VW, which owns more than 99-percent of Audi, won't allow it. Porsche has de facto control of VW, with a 35.1-percent share. The so-called VW Law, which allows the government of Lower Saxony ultimate veto power even though it has only a 20-percent share, has been the broadsword that both VW and Germany have been using to keep Porsche at bay. The law has been struck down at least three times by the EU Commission and a German Court, only to have politicians figure out how to rewrite it without changing the substance of it. VW's supverisory board recently declared it would need to approve any sharing between Porsche and Audi, and at the moment, Porsche can't overrule that decision. Ferdinand Piech, the head of VW, is in a battle with the Porsche family and Wendelin Wiedeking, the CEO of Porsche, over control, and neither is expected to budge. The risk is that since no one knows how this is all going to play out, a battle of egos and punitive reactions could interrupt development of and platform sharing between – and therefore the profits of – all three manufacturers' future products and technology.
Volvo has its locusts, Nissan has its bees. With 300-degree vision via compound eyes and instantaneous reflexes, bees don't run into things the way cars do. Nissan wants to halve the rate of car crashes by 2015, versus the company's 1995 tally, and is using bees to come up with a new generation of crash-avoidance systems that will be able to respond to obstacles in ways superior to humans. Whether bees or locusts, the key to making the technology work has yet to be created: allowing the car to act on information instantly, without complex processing. Information from the bees' eyes doesn't get kicked around their noggins first, it goes straight to the wings which immediately react to keep them out of trouble. More simply: they don't think about what they need to do -- they just do it. When bees do that, they end up unhurt. When humans do that, they end up on the evening news. To start down that road, Nissan's made a Biomimetic Car Robot Drive (BR23C) that knows how to act like your annoying sibling: it goes around you if it thinks you're in the way. Yet, even when the basic technology can be transferred to vehicles, there is still the issue of dimensions: the BR23C can rotate in any direction to sidestep barriers, but your car has a narrower range of options. Until the guy next to you can also respond instantly -- or we're all driving Nissans and Volvos -- we'll have to see how the technology shakes out.
Those wacky kids in Japan can do all kinds of things with their cell phones that those of us in the U.S. can't. Thanks to Nissan, Sharp Corporation, and NTT DOCOMO, the Japanese mobile communications company, they can now add car control to the list of possible cell phone features. The phone uses the two-way communication of Nissan's Intelligent Key System, the same thing you use on your G37. For now, it can only lock and unlock the car and start and stop the engine, but if it takes off we imagine they'll add other options later. This is about convenience, not necessarily about sense -- if your phone gets stolen, that makes your car one more thing that the villains can abscond with. The phone won't go on sale commercially until 2009, but will be demoed at the CEATEC exhibition in Japan later this month. You can read the full press release is after the jump, and get ready to overhear this in Japanese: "I called the wrong number and my car just drove off..."
Audi's stoplight detection system, called Travolution, has been given the go-ahead for expansion in the company's hometown of Ingostadt, Germany. Travolution establishes a connection between a red light and a vehicle, so that as a specially equipped car moves toward a red light at an intersection, stop light gantries fitted with communications modules can let the car know when the light will turn green. The car then lets the driver know what speed he should maintain in order to pass through the intersection without having to brake for the light and then accelerate again. The system's promise is in streamlining traffic flow, increasing gas mileage, and reducing emissions. An additional twenty A5 and A6 Avant models are being added to the fleet of cars with the technology, and fifty more stop lights will be fitted with modules. If you're in Inglostadt and you want to save time and money on your commute, follow the Audis.
FasTrak is an "electronic toll collection system" used in California. Once you set up an account, you get a transponder that simply debits your account balance whenever you pass through a toll booth. The system uses RFID technology to broadcast your account information to the toll booth receivers. According to Hack A Day, the system is anything but secure.
Among other problems, an attendee at the Black Hat 2008 conference in Las Vegas found that because the in-car transponders don't require any authentication, anyone with an RFID reader can get the unique ID from any car and then use that in their own transponder. Not only that, but you could also force any other transponder to take on a new ID because of the system's open over-the-air upgrading system.
To change the system would require legislative action since it's all defined by California laws, so Californians shouldn't expect a quick fix. Until -- and if -- a fix comes, we suppose the best that can be done is to make sure you scrutinize your FasTrak bill. And keep an eye out for guys kitted out like Star Trek yeomen wandering the park-and-ride commuter lots...
The rapidly shrinking US auto market has left automakers scrambling for any way to differentiate their products from the competition, and the fastest way to get the job done is with technology. Microsoft is all too aware of this, and the tech giant is betting big on automotive to give itself a larger presence in a rapidly growing field. Microsoft has increased both staffing and funding by 30% in an effort to get in on the connectivity and infotainment ground floor. Sync has been Microsoft's crowning achievement in the automotive space to date, with over 200,000 units sold so far and 1 m expected by the end of 2009. Though Ford owns Sync branding rights, Microsoft will be able to peddle the inexpensive system to other automakers in 2009. Microsoft's "Live Search" technology is also available to automakers, and it will spawn in-car systems that allow drivers to search for nearby businesses.
Since every other aspect of our lives is now interconnected, it makes sense for cars to follow the trend. Whether you love the Microsoft or hate it, having the 800-pound gorilla in the automotive realm is a good thing. We just hope we won't have to worry about a blue screen of death plaguing our family wagon.
Following two incidents in two weeks, it looks like the ballyhooed KERS hybrid system might not make it onto Formula 1 cars for 2009 -- at least, not the first races. Teams have begun to talk about how much difficulty they're having in building a safe system. KERS not only needs to work when the car is racing around the track, it also needs to be engineered properly in the event of a 300-kph accident.
In addition to Red Bull's smoke and fumes and BMW's bolt from the blue, Mark Weber said that teams are struggling to deal with the chemicals in the batteries. Supposedly, the stuff that runs off a blown up KERS battery is poisonous arsenic. Toyota's head of engine development said all the teams are having trouble, and Williams Driver Nico Rosberg appeared to doubt whether his team would have it ready by the first race of '09. The teams have scheduled to discuss the matter at their next Technical Working Group meeting. As for us, we can live with or without KERS. Just keep the slicks, will you?
We've heard it before: "We're going to collect the information, but it won't go beyond..." The latest take on "Let us help you with technology" comes courtesy of GM's OnStar, which is offering you the opportunity to have your annual mileage tracked. The info will be given to their GMAC arm, which will then see if you qualify for insurance discounts. That sounds good, right?
Of course, no one mentions the other side -- that they can also see if you need a higher premium. "You told us this car was just for weekend recreation, Mr. Smith..." Signing up for the OnStar service is voluntary, so it's not going to start watching you until you say so... yet. But if you really do think you're paying too much, then why not. They probably already know everything about you, anyway...
Honda and Nissan are looking for ways to make cars lighter, better, and more recyclable, both for their own benefits and their customers. We've heard about the increased use of aluminum to save weight; next on the heavy R&D frontier could be carbon fiber. Both companies have teamed up with Japanese carbon fiber company Toray, and Mitsubishi Rayon -- a Japanese version of DuPont -- to research new, less expensive carbon fiber for cars.
Their efforts will be helped by the government, which is injecting two billion yen into the project over five years. The plan is that by the middle of the next decade, they'll be able to mass produce a cost effective carbon fiber and use it to reduce the weight of cars by 40-percent. And when they're finished with it, they will also be able to recycle it to reduce production costs.
The current price of carbon fiber makes its use prohibitive except for ornamentation or for use on the most expensive cars. With the price of steel -- and cars -- expected to keep climbing, the mass produced, recyclable carbon fiber will make financial sense in the not-too-distant future. Add in the fuel savings from lighter vehicles, and fewer emissions, and it looks like everyone wins.
