From roads to bridges, from planes to trains,
from cars to bikes, and ships to busses.
  • How can small science help us travel such a
    big planet?

Nanotechnology Transportation Goals
Using nanoscience technology, scientists hope to
improve the transportation industry in three main
ways
  • Protect and Improve
    the Environment
  • Improve safety
  • Improve comfort

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.

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.

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!"

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.

Better Protection

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.

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.

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.

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.

A Better Catalytic Converter
Mazda created a new catalytic converter using
nanotechnology. Catalytic converters help to
purify exhaust emissions.
  • 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.

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). Thats a
    problem when working with nanoparticles due to
    the laws of quantum mechanics. (Quantum
    small). Somehow, Mazda has overcome the problem,
    and theyre not telling how!

19
Thats 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.

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.

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.

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?

24
Research Questions
To prepare for your presentation, answer
the following questions using reference materials
which can include the websites linked to this
webquest
  • What can be done to maximize the chances that
    humans will benefit from, rather than be harmed
    by, new developments?
  • If we can develop these technologies, should we?
    Why?
