Well, the first thing I can remember, is FIRE. The fire is falling from the sky, screaming, howling, and a huge smoked pipe is falling inside it from above... I don't know, why did they do it... Why did they take me to that awful, frightening place... I see this again and again, almost nightly. The falling smoked pipe, surrounded with fire, roaring like an apocalyptic trumpet from above... Other kids told me that they were seeing the green grass, the yellow sun, the butterflies... But nobody had seen a huge, black, smoked burning pipe from the skies..."

If that is clay and to be fired at those thicknesses it would have to be heated extremely slowly, like on the order of weeks, or months, to keep it from cracking. Actually, at those thicknesses, it is about guaranteed to crack no matter how slow you heat it. It will crack quite a bit from simply air drying. One can however keep filling the cracks, letting it dry, lather, rinse, repeat. Unless you have a lot of green energy high, or even bisque, firing stuff that massive is going to be very not-green. Glass working temperatures going on there Edited October 31 by darthgently Quote Link to comment Share on other sites More sharing options...
AckSed Posted October 31 Share Posted October 31 It is not fired with heat. It is literally fired out of a launcher. (English, everybody!) This is essentially adobe walls with carefully-controlled particle size and a touch of mineral binder. Quote Link to comment Share on other sites More sharing options...

Those are probably going to be bright in the sky. Astronomers will be yelling for them to be at least as dim as Starlink sats in 3, 2, 1 .., Cool idea though. Before I read the article I wondered if they were going to be big passive RF reflectors or what, lol. Would have to reorient for every connection, so nope.
