A partnership between Duke University and Boston College turned out to be very beneficial for the science world, as they obtained a metamaterial that absorbs all the light it gets (no, it doesn’t make things invisible), thus capable of generating more energy even than the solar cells.
It can’t be used as a camouflage, as it’s simply black, but scientists surely have other applications to put it to work into. The metallic material absorbs both the magnetic and electrical properties of electromagnetic waves over a certain frequency range, thus turning the light into heat. And as many of us already know, there are just a few sources of energy more efficient than heat.
The fact that science still finds new ways to produce electricity is laudable, but in the same time, it shows us that we have much to learn and that many unexploited areas of science are waiting to be unveiled. Meanwhile, it will surely be interesting to see how this discovery will evolve.
only us, humans, to think we know all and everything. there is probably a trillion times a billion trillion and more than a trillion more times that, of things, that we will never really know anything about because of our arrogance.
and this is a cool product, can this be used to generate eletricty for ours homes, 100% free of polution??? now thats smart!
you took my virginity away!
Hey, they developed black paint and convert heat to electricity! That’s new… : ( I don’t think they’ve really done anything to make a material that absorbs light and makes heat. Heat conversion is not the same as electric conversion. Converting light to heat and heat to electrcity is not new. I don’t think I wouldapplaud this just yet till I see real evidence it’s more efficient.

[...] New Material Absorbs Light Completely And Generates Electric [...]
I am reminded of 2001: A space odyssey by Arthur C. Clarke. Now if they can fashion that stuff into a perfect square and bury it in a moon crater they’ll have something worth writing about…
One interesting property of this type of material, Clarke imagined, would be an inability to cast a shadow upon it.
I wonder if it has applications in radar evasion?
i ate your cherry
nice but whats the cost per square inch of this material?

Great for the solar and energy industry, bad for the invisible and hunting industry.

Well, black would result if ALL light was completely absorbed. It is clear that at least yellow light is being reflected. I suspect we will find that, should some wavelengths of light truly be completely absorbed, they are not in the visible region of the EM spectrum. If this claim is true, it will be the first truly black body I have ever seen.
I should think so if it absorbs completely at radar wavelengths. That is a portion of the technological principles we employ now for B-2, F-17, etc.
Having read the many posts below, it’s time to start a thread on using water as a fuel.
I read an article quit a long time ago about Japanese scientists who had discovered “the darkest material on Earth” that absorbed 99% of the light that hit it. Are American scientists so ignorant of their own field that they have to re-discover things already uncovered in other areas of the world?
Christ Almighty! You’re ALL retards! Let’s think this through people! The question; Is it black, or is it invisible? Well, actually a little of both, and a lot of neither. In order to be seen, by any eyes, human or otherwise, the object would necessarily have to reflect some part of the electromagnetic spectrum. The statement in the article says “ALL…” light is absorbed. Well, that means nothing is getting reflected. Which means you can’t see it. By definition, that makes it “invisible”. But, our concept of “invisible” means we can see ‘through’ an object, or more accurately, see the objects behind it without interference. But with this substance that is not the case. The object itself is still physically present, and absorbing light, from all directions. This means the light from the objects behind it are also absorbed, meaning none of their light makes it to our eyes either. The gist of all this is that we “perceive” the object as being BLACK. This occurs for two reason, 1, no light is reflected, and 2, the object itself blocks the light from objects behind it so we can’t see them either. We perceive a “void”, an area that appears to be empty of everything. If either the object or the background is in motion, then the ‘void’ moves, and we detect the motion. This is how we would know the object is there. So is it black? No, not really, it just doesn’t reflect any light. Well, then is it invisible? Again, no, not really, it’s there, we know it because it ‘hides’ objects that are behind it. It’s all a moot point, because the only known objects that absorb ALL light are black holes, and I seriously doubt that we have developed the technology to create one ourselves…

I think I became invisible last night when the lights went out, just for a moment.
I fear I may be invisible even now… Can someone tell me how many fingers I’m holding up? Anyone?

hi
If any material abosorbs all the light and in turn looks black, does it mean people who are black in colour absorb more light than who are white?
Please somebody answer me. Do people of different skin colour absorb or reflect different amount of light? That is white skin reflect more light?
It is black Simon says so. End of story
