Is that why racing engines use black paint. It a good theory in it proper environment.
The racing engine thing cool black . Problem . Clowns like me who laugh at such things view in such a micro way. So guess what color I use. White . to top it off I am only one with cooling problems . Yep thats right We run to cool I have hard time holding 180. when I want 200 or 210 exactly .
This white reflect black absorb . Is that light heat or radiant heat. As compared to contact.
I don't care what color you paint that heat sink . Its not going to change anything Just don't paint die area lol

I feel like I need a decoding wheel from the bottom of a cereal box to sort out this post. Nevertheless, attempting to utilize dark surfaces to dissipate heat through black/grey body radiation is a bit of a wash on Earth due to the large number of other emitters present. Anything with high emissivity also tends to absorb electromagnetic radiation readily so it's a double-edged sword.
As far as racing engines are concerned, during the daytime and/or in the presence of other potential heat sources, I wouldn't think a black coating would help all that much. When running an engine in a cold, dark environment, a black coating might help.
The reason why emissivity is such a big deal in space is that you don't have all that many other emitters present if you're floating around in an empty void away from stars and such. And even if you are near a star, if you're orbiting a larger body that is blocking direct radiation from said star, it can still get very cold.

basically, its not the emissivity is the best way to get rid of heat, it is just the ONLY way to do so in a vacuum.

Well with my secret decoder ring. That I sell at bargain basement pricies. You would of found thats exactly what I said.

i honestly never heard of the practice... it sounds very marginal and "nerdy"... don't get me wrong, I am a nerd, but I am having a hard time imagining an average kid enjoying a cryptography project in his cereal.

It's more impressive that AMD finally has a core that clocks well at all, under any conditions. I think the last time that happened was the pre-SOI 90nm Athlon 64s. Since they've implemented SOI, they've barely outdone launch speeds.

There was a time when almost nobody would ever admit to that! :laugh:
You must be young, yet. Decoder rings and very basic cryptography were popular stuff with kids in the 1950-70's.
Or you can expel material, e.g., water into space. Of course you're now limited by the amount of water you bring with you.Originally posted by: taltamir
