Nanotechnology and the Automobile


When people think about technologies, they often either think of computers or automobiles. So whenever nanotechnology gets discussed, it always becomes necessary to say how it will impact our automobiles.
The answers arenâ''t very exciting. I recall that the big application that was touted in those heady days after the NNI was launched in 2001 was the use by General Motors of nanoclay-TPO composites in exterior steps for vans resulting in a 7-8% weight saving, a smoother surface and enhanced scratch resistance.

Then you got the more detailed examinations that included nanocomposites in polycarbonate automotive glazing, or nanocomposites for high-barrier plastics for fuel tanks and fuel systems.

The list can go on like this, but you get the pointâ'¿I hope. What weâ''re talking about here is just incremental advances in composite materials. Not particularly exciting, and itâ''s not as if these nanomaterials were specifically engineered for these applications.

But the fascination with the automobile is a strong one, and it has almost become obligatory to mention the car whenever you utter the word â''nanotechnologyâ''.

Along these lines, in the latest issue of Nanotechnology Law & Business they provided a link to an article entitled â''Top Ten Ways Nanotechnology Will Impact Life in the Next Ten Yearsâ''. So, of course, I was intrigued, and sure enough the automobile was included.

What was interesting about how they approached it was not the mention of nanotechnology enabling low-emission automobiles, but using the example of Oxonica and its liquid-based catalyst that reduces emissions for diesel fuels, EnviroxTM.

Whatâ''s interesting about this example is that it has nearly ruined the company. In testing of the Envirox product in diesel engines in Turkey conducted by Petrol Ofisi, the Turkish national oil-and-gas company, the results were disappointing. Oxonica claimed at the time that further tests had to be run, but any way you cut it the future of the Turkish deal looks as though it is finished.

This is not to say nano-enabled fuel-borne catalysts wonâ''t reduce emissions in diesel fuels, but the Oxonica example seems to be a poor one.

But the need to equate nanotechnology to the automobile gets really weird in the hands of futurists. At the recent LA Autoshow designs were submitted for the car that will exist in 2057. Nanotechnology figured prominently with Mercedes-Benz offering up the â''Silver Flowâ'' that will utilize micro-metallic particles that can be rearranged via magnetic fields into any form you choose. Hmmhâ'¿not exactly lighter weight composites for steps on a mini-van.

Nanotechnology: Futuristic Green Cars

What is Nanotechnology?
Nanotechnology is a branch of engineering that deals with design using very small particles and with the manipulation of individual molecules. The size of the particle is 1X10-9 meters. This will reduce the size of an machines and give more efficiency.

What is the use of nanotechnology in Automobile?
In future because of this tiny technology the materials used in cars will replaced by the nano materials, which will reduse the weight of the Car but it is strong enough like as of current materials. Because of this weight loss the efficiency of the Car will increase it will reduce the emissions.

Will Rodgers, director of General Motors' Materials and Process Laboratory, said his company has used nano materials on several vehicles. The center console for the Chevrolet HHR compact wagon, for example, uses high-tech plastic.

In Future the windshield is coated with the material that fills the microscopic nooks and crannies on windshields, making those surfaces perfectly smooth. When a person drives during a rainstorm, the rain naturally falls away, reducing or even eliminating the need for wipers. So this windshield resists water, dirt, salt and bird droppings.

Nanotechnology Unfolds Futuristic Green Cars

Recently, automakers have unleashed their environment-friendly concept cars that are expected to be manufactured using nanotechnology. The latter is a technology of building tiny machines using functional systems at a molecular scale. According to experts, nanotechnology, in its original sense, means projected ability to assemble items from the bottom up, utilizing techniques and tools being developed these days to make complete, high performance products.

LA Design Challenge: Green Cars of the Future

Doc Brown would have been proud. Nine automakers have submitted entries in the upcoming Los Angeles Auto Show’s Design Challenge, a competition aimed at conceiving a futuristic car that’s environmentally friendly, by both design and fuel source, and can be recycled after five years on the road. It’s the third such competition sponsored by the auto show, and all entries are strictly two-dimensional. Judges choose a winner based on originality, environmentalism, safety and how well it reflects Southern California’s “green” lifestyle.

For details on the winner, stay tuned for our full L.A. Auto Show coverage coming at the end of November. For now, here’s a sneak peek.

Acura FCX 2020 Le Mans:
Try saying it six times fast. The Le Mans looks like the Batmobile, but uses lightweight, recyclable materials. A hydrogen fuel-cell drivetrain propels it to take on a future 24 Hours of Le Mans, while molecular nanotechnology allows lightweight construction.
Thumbs up: Motors in each wheel assist the hydrogen powertrain, effectively creating AWD.
Thumbs down: Drivers must lie flat on their stomachs.

Audi Dynamic Space Frame:
The Space Frame has built-in channels to facilitate an elaborate drive-by-fluid system. That’s right: Instead of a traditional mechanical linkage between the steering and the wheels, there’s a fluid coupling. The car’s suspension also features liquid portions that are electrically charged to alter the car’s ride.

Thumbs up: The minimal overhangs and gigantic wheels project an athletic stance.
Thumbs down: The suspension concept exists today, but the fluid driveshaft seems like a giant torque converter – hardly the stuff of efficiency.


Hummer O2:
GM’s California design studios say the O2 has a net positive effect on the environment thanks to its algae-filled panels, which turn carbon dioxide into oxygen. Other features include a fuel cell drivetrain and parts made from post-consumer recycled materials.

Thumbs up: Hydraulic motors power all four wheels, and carbon dioxide from each motor is routed toward the algae.
Thumbs down: The algae need to be changed annually. We doubt Jiffy Lube will offer a $29.99 special.



Honda Extreme:
Honda’s Extreme can take on different forms – from a pickup truck to a low-slung sports car – thanks to interchangeable body panels. After five years, the polycarbonate chassis can be recycled.

Thumbs up: Evolving body styles on the same car? Sign us up.
Thumbs down: Sheet-metal makeovers come courtesy of Honda Sustainability Centers, which look like miniature airport terminals with hokey status readouts like “transforming” and “transformation complete.”

Mercedes-Benz RECY:
The RECY, an open-air roadster that looks like it took a few cues from the 1980s SL, offers wood, alloy, glass and rubber materials said to be 100 percent recyclable. A BlueTec diesel engine provides power. Design inspiration came from wooden yachts and sunglasses, Mercedes says.

Thumbs up: Unlike many objects of automotive inspiration, these things actually show up in the concept. The two-frame windshield looks like a pair of Oakleys, and the body has a nautical profile.
Thumbs down: A long aluminum brace splits the two seats. Seems like it could put a crunch on shoulder room.

MINI Biomoke:
The Biomoke sports biodegradable paneling infused with palm tree seeds. When the car expires, the panels compost and the seeds sprout. There are no windows – Mini says the open-air cockpit is best for Southern California’s temperate climate. And like Mini’s real cars, the Biomoke’s exterior can be customized to fit its owner’s tastes.

Thumbs up: We’re still chuckling about the palm tree seeds.
Thumbs down: Temperate climate notwithstanding, a mile on the 405 without a windshield could bury drivers in grit.



Kia Sandstorm:
Kia says its two-seat runabout can hit the beach or navigate through highway traffic. Its aluminum safety cage protects occupants, while cargo space can accommodate a barbecue. Power comes from a biodiesel hybrid engine with plug-in electric capability and recyclable batteries.

Thumbs up: It looks like a genuine dune buggy, so it’s sure to be a hit at the beach.
Thumbs down: We’re all for minimizing waste, but having detachable recycling bins inside the cabin seems a bit overboard.


Toyota RLV:
The Renewable Lifestyle Vehicle seats two, one behind the other. Power comes from an electric powertrain or bicycle-style pedals, the latter for situations like bumper-to-bumper traffic. A pop-up roll cage and active headrests aim to protect occupants during a rollover, and the floorboard is made from bamboo and aluminum.

Thumbs up: Pedaling recharges the battery, and the wheels telescope outward for better high-speed stability.
Thumbs down: Since you’re giving him a lift, there ought to be an extra set of pedals for the passenger.


Volkswagen Nanospyder:
The Nanospyder uses billions of spore-like nanobots – complete with eyeballs, mouths and tiny VW logos – that bind together to create the vehicle. Impending collisions can be picked up by the lead bots, and the information can be sent elsewhere to bolster certain sections of the vehicle.

Thumbs up: Hands down, Nanospyder is the coolest name here.
Thumbs down: Stability depends on these little critters getting along. What happens when you’re doing 65 on an overpass and the bots holding the wheels together decide to mutiny?
