6. Nanotechnology Transportation Goals • Protect and Improve the Environment • Improve safety • Improve comfort Using nanoscience technology, scientists hope to improve the transportation industry in three main ways: http://www.rff.com/Transportation_Plan.gif

7. 1. Behind the Wheel It won't be long and you'll be driving!  Imagine, nearly three quarters of a billion cars are currently being driven around the world.  Pollutant emissions and the need for recycling and disposal are a big concern. Researchers, developers and industry are searching for new nanotechnology solutions for the transportation industry. http://www.discovery.org/scripts/viewDB/index.php?command=view&id=209&program=Cascadia&isEvent=true

8. Areas of Vehicle Nanoscience Research Thanks to nanotechnology, look for vehicle improvements in the following areas. A few of these will be described on the following pages. • Anti-glare and dirt-resistant window materials • Wear-resistant super-grip tires • Corrosion protection  • Lightweight materials • Individually varying colors • Wear-resistant  mechanical parts • Electronic safety sensors • New drive and emissions concepts Ames Research Center conducts research using nano-scale assembly to create sensing elements, among other things. They are using protein-based nanotubes, potentially capable of self-organization and replication. http://www.sti.nasa.gov/tto/spinoff2001/ames.html

10. Bling! An Australian company nano-based water repellant product is said to increases visibility in wet weather by up to 34%. The company website states, "Nothing clings to Bling! Bugs, Snow, Ice and Rain comes right off!" http://www.greentechforum.net/category/news/2007/07/04/if-it%e2%80%99s-in-bling-nanotech-must-be-mainstream http://nanopublic.blogspot.com/2007/07/need-nano-bling.html http://www.instructables.com/id/Increase-Miles-Per-Gallon-Instantly/

11. Windshields    Designs are currently being developed for windows that wrap all the way around vehicles. Nanoparticles and nanofibers make this possible. These nanoparticles provide extremely high transparency and stiffness. Besides making driving safer with better all-round vision, it also would be lighter. Look for transparent solar cells for car windows, soon, with the help of nanotechnology. Source: Dr. U. König, DaimlerChrysler AG http://www.nanotruck.de

12. Better Protection Click on the following link to find a list of ways vehicles can be protected by just one nanotechnology company! Nanotechnology Innovations

13. Your Bike and Nanotechnology To save energy and for exercise, some of us ride bicycles, but a lightweight bicycle is always easier to pedal. Carbon nanotubes are tiny cylinders of carbon atoms that have 100 times the strength of steel but weigh much less. Nanotechnology has helped make a bicycle that weights less than three pounds and is extra durable. http://discovermagazine.com/2008/feb/06-see-through-bike http://delta7sports.com/products.html

14. MechanicsBetter Batteries with Nanoscience A123Systems has taken a different approach to developing nano-enabled car batteries. The battery uses the advantage of increased surface area of particles at the nanoscale nanoparticles to provide a quicker source of greater power. http://www.nano.org.uk/features.htm

15. Fuel Cells using Nanotechnology • Cheaper fuel cell vehicles can be made possible with the help of an enzyme connected electrically to a carbon nanotube. The National Renewable Energy Labs in Colorado combining the super tiny strands of carbon with hydrogenese, a "biohybrid" catalyst. This process eliminates the need for platinum, an expensive component in traditional fuel cells. http://www.physorg.com/news114703218.html

16. Lighter Nanotech Cars Save Fuel • Ford has an idea for dealing with the energy crisis. Nanotechnology can make cares 250 to 750 pounds lighter without compromising the structural integrity of the vehicle. Lightening the vehicles will have much better gas mileage. http://jalopnik.com/380964/ford-looking-to-nanotechnology-for-future-design http://blog.wired.com/cars/2008/04/ford-turns-to-n.html

17. A Better Catalytic Converter With nanoscience these catalytic converters use 70 to 90 percent less metals, like platinum, rhodium and palladium, which speed up chemical reactions of pollutants such as nitrogen oxide, carbon monoxide and hydrocarbons. The converters rely on nanoparticles of the catalytic metal, each less than five nanometers in diameter, embedded into fixed positions onto the surface of tiny ceramic spheres. See how it works on the next page. Mazda created a new catalytic converter using nanotechnology. Catalytic converters help to purify exhaust emissions. http://www.nanowerk.com/news/newsid=2913.php http://maremare1225.files.wordpress.com/2008/03/catalytic-converter-location.jpg

18. Nano-sized Secrets In the past the problem of placing nanoparticles on a surface like this resulted in the migration and collection of nanoparticles into one place, (agglomerating). That’s a problem when working with nanoparticles due to the laws of quantum mechanics. (Quantum = small). Somehow, Mazda has overcome the problem, and they’re not telling how!

19. That’s Nano-Slick! Using nano-boric acid particles in motor oil reduces friction in automobile engine parts can have less friction. This boric acid 'rose' shows the intricately layered microscopic structure of the compound. http://nanotechnologytoday.blogspot.com/2007/08/nano-boric-acid-makes-motor-oil-more.html

20. 3. Infrastructure Nanotechnology can also be found in the construction and monitoring of roads.  Nanomaterials are found in construction materials including concrete, asphalt, aggregates, and even pavement marking materials. Research into nano-phosphors could someday illuminate the streets, not from above, but from within! Guardrails may someday heal themselves, or concrete or asphalt that heal their own cracking using nanotechnology. http://pubsindex.trb.org/document/view/default.asp?lbid=847888 http://whrpnews.org/images/12-07/joint_distress1.jpg http://radio.weblogs.com/0105910/2004/08/04.html

21. Sensors Advanced sensor technology using nanochips is available for transportation applications. Due to the lower cost and easy installation, sensors have been placed in the pavements, bridges, inside concrete and asphalt, and even inside vehicles. There are nanosensors on the Golden Gate Bridge to monitor its behavior.These nanochips can provide wireless communication to improve safety. http://radio.weblogs.com/0105910/2004/08/04.html

22. Social, Environmental and Ethical Concerns • Might these nanotechnology developments in transportation infringe on human rights?  • Could any of them decrease privacy of individuals?  • Could the use of nanotechnology for transportation have unwanted and negative environmental effects? • What economic impact could the use of nanotechnology in transportation have on producers, consumers, and other industries? Might they be negative or positive?

23. What About Your Rights? • If so, are these developments • more important than • Your privacy?  • Your rights as a citizen?  • Your rights as a human being? • Are the answers somewhere in between?
