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"

Police car chases

They have just made police car chases a lot more harder, and interesting as well!

Wow.. they invented something that already exists.

Well I don't know if it works the same way but there is temp sensitive automotive paint you can buy now:

Re:Computer cases!

[pickyouupatnine]

Well.. anything with a temperature regulation requirement. I suppose the question would be, what sort of temperature constraints do these paints work under? Or can they be 'configured' to work under any fixed range?

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.

intercoolers & radiators

[doubtless]

Actually this might be useful if it's coated on radiators or intercoolers for testing and comparison purposes. You can visually inspect the efficiency of the product.

Not only awesome, but therepeutic.

When I was a kid, I had chickenpox. My case was an especially severe one, and I was bedridden for a while with high fevers, which we kept down through medication. I just lay in bed in my hypercolour shirt, and when it started to change colour (due to the fever beginning to rise), Mum could tell the meds had worn off and I needed another dose. Better than mucking around with thermometers every half hour or so.
