Cool for space travel stuff. Forge metal and print a solar cell directly to the surface.

garbage. They just made a really black coating that's only useful for concentrated solar thermal. And wow it improved output power efficiency of a TEG by 130% ...compared to shiny tungsten. That's fucking pointless. If you paint something black of course it's gonna absorb more heat than something shiny, like how's this compare to other approaches already used in solar thermal to make stuff black? Concentrated solar power is obsolete and more expensive than photovoltaics

it's just black paint. You can print solar cells directly on to surfaces in space though. You can make a solar cell by using vacuum deposition, which works in space because space is a very high quality vacuum. It's even possible to pave solar cells directly onto the lunar surface.

The issue is getting good enough silicon though. It becomes much easier to make silicon once you have access to hydrogen. Hydrogen's also useful for propellant and if we can't make propellant in space, there's really not much point in making solar cells.

this has nothing to do with rare earth metals. Nothing at all. Metamaterials get their properties primarily from their structure not the elements involved, meaning that you can avoid the use of rare earth metals.

No they aren’t dumbass. No metal can “run out” except something like uranium which decays, but that takes millions of years. They don’t magically teleport to another universe after being used, and there’s fucktons of every desirable metal available on Earth’s surface and in the seafloor which can and will be exploited.

Environmentalists deserve the rope.

surface treatment, paint, it's pretty much the same thing. But since you're being autistic, I'll concede that all they did was make metal black. Black metal isn't a solar panel.

if you read the fucking paper it's more than just an etched nanostructure. They have to deposit a layer of TiO2 on top of their etched microstructure so that it doesn't burn away. Might as well just be paint at that point. Not like it fucking matters anyway, it's just metal that's black. It ain't a solar panel, just something that's really black. Turning metal black with a femptosecond laser ain't new either:

That's from way back in 2006.

No they don't. They treated a lightbulb filament through the glass of the bulb. The nanostructures are etched by a femtosecond laser.

Great minds discuss ideas, concepts and facts. Small minds obsess over people and personalities. When small minds like yours are confronted with uncomfortable scientific truths, they run away from the facts covering their ears and eyes while screaming the name of the individual who presented the information.

It is. On a closer reading they don't detail the lightbulb experiment in this paper, however the nanostructures are etched before the application of any film and is completely unnecessary for objects in oxygen free environments.

This is far from "paint" and you are a retard if you continue to try to argue otherwise.

and if you're using highly concentrated sunlight for solar thermal you can't put your solar absorber in an evacuated tube. Pretty much the only merit of this work is that they can make something very black that doesn't burn up when they heat it up and for that they have to coat it in TiO2.

If you think that's the only merit of this work then you are pants-on-head retarded. Being able to control the color of a material without affecting it's properties is ground breaking even without considering the work that will build on it.

been demonstrated before, pic related. No, those aren't oxide layers. It's been known that you can change the color of the surface of metals using femtosecond laser pulses since about 2008, here's an article on it:
