Car Paint Changes With Temperature
PlayfullyClever writes "It's now common to build materials which can change colors depending on their surrounding environment because of progresses made in colloid chemistry. But now, German researchers have gone a step further. They've used ion bombardment and gold metallisation to produce new particles whose bonding behavior can be chemically tailored. This could lead to new shimmering car finishes which can change with temperature or humidity, new cosmetics, but more importantly, to new applications in optical data processing"

Hypercolor shirts were awesome!
there's more than one way to do me.
Maybe it's just me, but what's so great about using this as car paint? Certainly the article could have expanded on other uses. On the other hand, it might pretty good for my low-rider
They have just made police car chases a lot more harder, and interesting as well!

Anyone remember those Hotwheels toy cars that changed colour with hot and cold water? Or Hypercolour T-shirts? No? I think this technology is a little late for the 80's...
I seem to remember having like 30 hotwheels cars that did this
...would major car manufacturers use it on their car models?
Or how about a beow... never mind.

I forsee one possible flaw with this technology. I am from Michigan and we see hot summers and cold winters. In winter, your hood will be much warmer than the rest of your vehicle due to the engine heat. I would think you would end up with blotches all over your car. In summer, the air conditioning, I would think, would produce similar results.

They actually did that in the 1983 movie "Deal of the Century"...
IIRC, Gregory Hines was pissed off at some dude, and caught him in a parking garage. The guy was driving a Firebird with the flame paint job. Gregory Hines said something like, "I like your flame job... I'm gonna give you just a little touch-up," and then torched the car with a flamethrower. Kept repeating "Just a little touch-up" every time he pulled the trigger on it, in a sort-of homage to Donald Pleasance blowing away Issac Hayes at the end of Escape from New York ("You're the Duke!"... [machine gun fire]... "You're the Duke!"... etc).
There was a TV show about a car used by govt spies. It was called the Viper, and besides having cool gadgets and weapons, it could change color. Unfortunately it was cancelled pretty quick. I liked the idea, tho.

The police will complain once these cars finally become readily available. You see, a criminal could commit a crime in the Texas heat as an example. This criminal then drives a few hundred kilometers north where the temperatiures are cooler and viola, what was a red truck is now purple with stripes! What follows is chaos!
This could be used to change the car to a color that attracts heat when it's cold, and repels heat when it's hot. It might help somewhat with the heat and cold, but would the particles add more heat so the heat repelling functions don't really work? I'm thinking no, as I believe it happens on a micro-level, but I could be wrong.

Criminals running won't even have to run to the local safe house anymore to get a paint job , just a quick stop into the carwash or a few buckets of icewater and that green toyota they were chasin is now blue.
its hard enough to find my car in a parking lot when it has normal paint. imagine trying to find your car when it changed colors. its down right impossible.

How would this work, exactly?
"Wow Carol... that new rouge really looks nice on you!"
"Thanks for noticing, Sue - but it only looks nice when the temperature is below 75 degrees... any warmer than that and I'd look like a total whore!"
Damn - I have trouble remembering where I parked my car at the best of times. If it's gonna start changing colour too then I'm really screwed!
now that would be cool...and seriously, imagine how useful this could be..for example, really really really stupid parents could put bathing suits on the fruit of their loins and then just visually scan for major color changes (excluding the natural yellows and browns ;) - then they could get 'em outta the sun before they crisp up or wash out from too much sun...
or for my dogs maybe, like a collar that lets you know if it's wicked cold in boston - in case you're so cold and dumb that you'll forget to know it's cold unless you look at your dog. are you following me? this won't work for very small dogs, they get cold very easily.

I can tell you this WON'T be used in cars anytime soon. I recall at the Society of Automotive engineers seeing a similar paint that changed colour depending on the angle you viewed it at. In addition to being ridiculously expensive, it was later decided you couldn't paint your car with it, since it would complicate things if law enforcement needed to locate your car.
This could lead to new shimmering car finishes which can change with temperature or humidity, new cosmetics, but more importantly, to new applications in optical data processing
but more importantly, to new shimmering car finishes.
new cosmetics, but more importantly, to new applications in optical data processing How can you tell a geek submitted this? Women could look prettier, but no, optical data processing is far more interesting.

1. Develop new automotive paint that changes colors.
2. Pay to have featured episode on MTV's "Pimp My Ride" with said paint.
3. Sell to all people who want to "pimp their ride"
4. PROFIT!
Didn't Kate Kestrel's car do this?
The hypercolor shirts from the 80s sure sounded neat in theory, but in practice, it basically accentuated your sweaty bits. Likewise, if this is put to use on cars, you'll probably end up with a hood that's a different color from the rest of the car. awesome.
I am Leviathant and I approve this message.
So now after a cold winter night I go looking for my silver car, and I can't find it because it's now BLUE. Great!
My car has that paint! It's activated by salt on the winter roads and other things. I've had to wait a long time for the colors to change, but there is a sort of reddish-brown highlight effect behind the tires, at the tip of the hood, and above the windsheild, surrounded by a drab gray halo, then the silver-gray regular color of the car. It looks pretty amazing!
I cried real tears when Li Mu Bai died.
Wow a life-sized version of a HotWheels car I owned as a kid, one that changed from red when warmed, to white when cooled. So I left it in the fridge for a few days and it never reverted back to red ever again.
So don't place your ion bombarded car in your fridge (for too long).
Paint parts of the car engine. I wouldn't mind knowing that when my intake manifold turns from white to red that it is at normal operating temperature. But if it should happen to turn purple, it's running too hot.
Someone hates these cans.
Yeah: hypercolor shirts that changed colour when you changed temperature - showed where you were sweaty etc.

You can't be serious. Obviously, car paint that changes with temperature is far more important than new applications in optical data processing. I mean, people won't be able to identify my beat up Corvette when I'm speeding because its paint will be red when I'm going 100mph and the engine is hot, and it will be blue when I park it.
(For the humor impaired: I don't speed and I don't drive a Corvette, OK?)
How long has Roland Piquepaille been working for ZDNet? Is this news to anyone but me?
A local car spray shop has been advertising heat sensitive paint jobs for at least the last 5 years (mainly for bikes and smaller sports cards probably due to cost) the paint is a usually a metallic purple on warm days, and goes a green or blue when the engine heats it up or if left in direct sunlight. I can't really see anything that makes this any different.
The "Q" type character demonstrated this by putting placing a green hat on a dessert vehicle.
It would be dial to be based on voltage and frequency so that you can change your car's color by selection.

When I was younger, some 15 years ago, I had miniature cars. I had some using that "new technology". They would change from grey to orange when holding them, just by the heat of my hands. And when submerged in cold water, they would become blue, almost like if the water was dissolving the paint. It was fun at that time. I wonder why only now we use that paint for cars.

i had a little toy car about 5 years ago that would do that ... if you put it in ice water it would turn blue, and when you took it out and warmed it up it would go back to bright green ...

Imagine a cold rain on a warm hood...
Do you have your hood up a lot?
I guess you could put a camera under there to see the color.
Or you could just put a temperature sensor on there (with alarm) instead. It's cheaper.
BTW, intake manifolds should run pretty much at ambient. You want cool air into your engine, and a hot intake manifold would run counter to that. Additionally, intake manifolds are naturally cooled by the cool air coming in.
Exhaust manifolds get got.

Every time I've seen any heat-sensitive color changing technology used (Hot Wheels, Hypercolor T-Shirts, G.I. Joes, etc) the range of color always diminishes over time. Has this kink been worked out yet?
I'd be more interested for the glass in the cars to change tint in heat or brightness like some types of eye glasses do. I haven't seen this yet, but maybe it exists already.

Womderful - there has been a breakthrough in dye technology recently that is very similar to this new paint tech. http://www.zubbles.com/ - Check out the popular science on the decade long search to make colored bubbles and the depth they had to go to find the dye tech breakthrough to do this! Fastinating!
Horns are really just a broken halo.
I fail to see how this is that new. I remember seeing a PT cruiser outside of my HS when i was maybe a sophmore and was wondering if I was going crazy since it looked like it had two colors (due to sunlight hitting parts of it). and I'm now a junior in college. So yeah, this has been around for a while...
In undeveloped countries, the consumer controls the market. In capitalist America, the market controls you.
I guess that depends on taste. It will probably look weird when your engine heats up and the hood on your car starts to develop a green spot on it. Or how about that "ass-print" where you sat while bragging to your friends about this fancy new paint job you've got. ;-)
However, I see nothing new in cars that change colors by temperature? My kids have had cars that change colors by temperature for a long time. They even have toothbrushes that change colors when the temperature change.

This is called thermochromic paint, and it's been available on the market for a while now.
Here's a company that sells thermochromic paint, their website has pictures and even videos of the color changing in effect:

Well, I was origionally writing a post detailing adding weight to the rear as a sollution. Then it dawned on me. Front wheel drive cars have a tendancy to understeer, not oversteer. Rear wheel grip is a non issue because they do nothing but roll, while the front must turn approximately 80% of the weight as well as apply forward force and resistance.
The CRX is also a front wheel drive car with an obscenely high skidpad rating. So you're right. If a FWD car has a tendancy for the rear end to slide, the engineer/driver is to blame.

More importantly, does it share the limited lifespan of Eclipse and Xposure coatings? I think they "wear out" after a year or so.

find my car in the parking lot as it is--and it doesn't change color day to day.
During the summer, when it is 110 degrees F. outside here in Arizona, I would want a white car or truck because it best reflects heat. During the winter, I would prefer beige because dirt does not show up as well on beige paint. When humidity is extremely high I would like the car to be yellow or lime/yellow so that it could best be seen in fog, rain or snow. Surprisingly, red is hard to see at night or in fog and that is why so many fire trucks are now yellow or lime colored in recent years. It used to be that all fire trucks were red before they realized that red was so hard to see red at night or in fog.
At night I would prefer white, yellow or lime/yellow which shows up best at night. Perhaps they could also make their paint change color at night by detecting darkness by responding to the lack of ultraviolet light at night. At no time would I ever want a grey car because they are the same color as asphalt and it is harder to see them coming. Do people that drive grey cars ever notice a problem with people pulling out right in front of them?
Someone else has already commented on the problem of police looking for a certain car and not not knowing what color car to look for. Another person has also commented on the fact that some portions of the car such as the engine compartment would be warmer and be a different temperature. Under certain conditions we would end up with odd two tone patterns. That might be OK.
The paint has been peeling off of my 4WD truck in recent years. Please have this product available in time to be used when I have my truck repainted. At the moment the bare siver steel portions don't look too bad and in the Arizona climate bare steel does not rust even after several years of exposure on the road.

Seems he is a bit late ? There has been a simpeler 'pimp-my-car' program in the netherlands recently where they pimped a car with this 'technique'.... if you put your hand on the paint the paint collors the shape of your hand and u can see it, although it wasn't a very nice look when the car was running since the hood of the engine discolored because of this when driving......

Your car's registration includes the base color of your car (I'm not sure what percentage is required - but basically if it is perceived as blue, then your car is registered as being blue, even if you've got yellow and red flames on the hood).
If you have your car painted another color, you have to declare this and get your registration updated.
If the color doesn't match what the registration says, you can be fined.
A car which would change color frequently, such as due to temperature, would thus more than likely get you into trouble - at least until legislation allows for the registration to note two colors, under specific conditions, or something like that... or that bit gets dropped entirely, which is unlikely; law enforcement for example will be on the look-out for a car of a certain model in a certain color

I would love this, speaking from the country with the most automated speeding camera's in the world (Netherlands, probably in absolute numbers even the most). These photo's are only valid if it is your car in the photo. If the paint color doesn't match the specified color in the car registration: invalid ticket. And if the police stops by your house to check the car, its cooled down, so no ticket for an invalid registration. But there probably make some rule, for this too (america might have most lawyers, where sick of the civil cervants making rules for everything).

I don't know how each and every municipality handles car registration and plating. But, where I live, if you paint your car a different color than what is on the registration, you must update the registration or face fines/impoundment. If the cop looks up your plates, and it says red, but he sees blue... he's going to pull you over. This will keep happening until you A) lose your car, or B) a court decides in your favor that you somehow have the legal right to have "mood paint". I highly doubt B will happen. I've seen enough problems with friends back in high school trying to defend window tint (only to be forced by a cop to rip it out right there on the spot).

Courts rarely seem favor the car modifier when arguments of public safety and the needs of law enforcement to do their jobs are in question. Accommodating the driver's taste in paint is not on the court's priority list. Accurate registrations for law enforcement would outweigh taste.

Do what is right and let the consequence follow
They do soak heat from the block. But the constant inflow of cool air takes most of the heat away. As to burning my hand on one, I couldn't say, it depends on the engine. But do note that the intake manifolds on nearly all recent cars is now made of plastic. High-density-polypropelene often. That's literally the same as garbage bags, and I'm sure you know that polyproplene doesn't tolerate much heat at all, I'd be surprised if you could burn your hand on it before it became soft to the touch.
1 24290.
As to your plastic spacer, it will do virtually nothing. Your intake manifold cannot remain completely cold in a closed space that is hot. Some heat from nearby parts is emited as infrared radiation, and it will hit your intake manifold and heat it up some. Furthermore take a little class in thermodynamics and see how much insulating power a thin gasket which is under compression (and thus has no insulating airspaces in it) is worth in insulation.
I challenge you to do some actual tests on your intake manifold. Like I did with my Xbox 360 http://slashdot.org/comments.pl?sid=169465&cid=14
I think you'll find in good testing that the reduction in heat soak into the intake manifold under normal conditions is insignificant. If it weren't, the manufacturer would have put in a spacer themselves, gained HP or MPG and reaped the rewards from CAFE regulations or in the free market.

The cops aren't surprised to see another Lamborghini so close (it must have been near Carmel, CA) and obviously don't make the connection.
Here, the car changes color from the cold water and you don't have a mess of other-colored paint.

How much do you want to bet the second that car hits the road, people will be sueing the car maker for distracting them into a wreck?

His latest stunt involved standing on the side of the road with no shirt on and advertisers bought space on his chest. The cops stopped and told him he could stand on the corner of the road like that because he was distracting drivers and he would causea wreck.
