phys.org is often just regurgitation of press from original sources, typically university press sites. Here's a better source URL: http://www.jacobsschool.ucs

- richmarr 12y agoThanks. It's nice to be able to read the article without the "37 People With The Worst Eyebrows You'll Ever See".
- marcosdumay 12y agoWhat's as useless as the pointed article. I tought the university PR would care to add such things as absorption rate of infrared, and why should I care about this instead of looking at traditional black nickel. Any random black paint absorbs more than 90% of the light, and lots of black coatings survive 700°C.
- VLM 12y agothats why the story itself (which is a couple weeks old) and most discussion isn't catching the "real story". You can find materials and substances that'll survive years at 700C although its non-trivial (not home depot, but no challenge for real engineering). And you can find materials and substances with ridiculous awesome IR profiles that are unfortunately incredible fragile or at least not "engineering useful" tough. But both characteristics in the same material is where the real story is. Its pretty cool. There is another aspect of industrial scale use, not discussed in the weeks since the story came out, where for example, nickel oxide powder has some serious issues for lungs, and no one seems to know the toxicology of this new stuff. I donno where this stuff fits on the continuum of health, if its better or worse that your example of nickel oxides. It would suck if everything downwind turned into a superfund site, then again maybe its harmless as a charcoal bbq. I guess a bad computing analogy would be its not very hard to find a low power computing device. Think of TI and microchip pic series of picowatt or nanoamp things. I've fooled around with the 10F220 series for no reason, "just because". And its not hard to find a computing device that does stuff really fast, any ole COTS desktop CPU or high end video card has interesting specs. But finding a processor that simultaneously uses nanowatts of power while making gigaflops of calculations, in 2014 anyway, would be pretty impressive. And getting a good ratio of flops/watt while being engineering-worthless isn't that impressive, but getting a good ratio of flops/watt while being engineering useful and deployable is really cool.
