Test boats (dinghy size) weren’t stable outside of arctic conditions. It just didn’t work.

Okay now that's brand new information entirely. Where'd you get that?

Oh, uh… wikipedia had some. They did a test on a Canadian lake and the material kept flowing naturally out of place (because ice is like glass; despite being a solid, it slowly deforms due to gravity), so it would have had to be braced by other materials, defeating the purpose of a mobile ice aircraft carrier.

That sounds like you're describing the tests done with ice models. The entire point of the pykrete is that the sawdust acts as a brace, like rebar in concrete.

Disappointing if true. I'd be interested to see the exact schematics they followed, mixture/proportion chosen for pykrete and design for the ship itself. Their concept may have failed for reasons entirely unrelated to the base concept; did they test 4% sawdust vs 12% sawdust, or use other materials in the admixture, etc.

The stuff apparently performed amazingly well at stopping bullets. You'd think there'd be some use for it.
