I'd pay for it, if it was embedded in car paint.

#14Earlier quoted context omitted.
As a thought experiment, we release 40 billion tons of co2 per year. An average skyscraper weights around 250,000 tons. So that would be the equivalent of 160,000 skyscrapers worth of this stuff. Hong Kong has the most skyscrapers current at 317. So it would be the equivalent of building the skyscrapers for a city that is 500 x the size of Hong Kong every year. Not that you'd have to build skyscrapers with the materi…
Skyscrapers are mostly empty space inside. The Great Pyramid of Giza weighs about 6 million tons, so we’d be producing about 7000 of them annually. Maybe we could just plop them all in the ocean? ;)

#15Can these surfaces "get cancer"? As in, for some reason, the reaction continues way beyond simply healing the crack?

#16Lime-based mortar has been doing so since the Roman times.
Of course this is development is different, but it's still not scalable in any way. If your material isn't alive it won't last long, the catalysts always decompose or degenerate fast.

#17What stops the thing from growing indefinitely, but also fast enough when damaged to return to the "original" state?
If there's a "surface coating" which when damaged, causes the "inside" to "grow" again, how does the coating repair itself, to stop the "inside" from growing beyond the original surface?

#18Oh man, here comes the grey goo.
I say, bring on the grey goo! It's simply a distillation of life's ultimate purpose, so why not use a more efficient version?

#19Yea, we will call it "Amber" :)
Re: Self-healing material can build itself from carbon in the air
#20I wonder how efficient it is. If a square meter of the material were to be placed in 1000w/m² sunlight, how many grams of carbon can it scrub per hour? Can the carbon be easily recovered? How many break/repair cycles can this material do without deforming or degrading?
