Read the article, scant as it was. They seem to already use this stuff to insulate houses, more or less.

What about the heat caused by the chemical reaction? Never mentioned. Not that I am a chemist (oh Blast, help me out here) but wouldn't it cause hyperthermia?

So the foam comes out in a block. But looks like they have to gut you like a fish to get it out. Hey buddy, nice zipper there. Ouch.

Seems to me the foam can't expand too much, but as it is in the wound track it should seal it. Unless of course, the bowel or intestine has a hole in it and the foam just goes in there. C-rat cheese has nothing on this stuff.

I dunno. As to a future system that works automatically - no thank you very much. I would be in constant fear of a malfunction and would disable any automatic feature.
