Out with concrete slippers... slip into some concrete canvas.

This is so not telecoms, but I really love these kind of wacky ideas that have practical use!  These guys have come up with an inflatable, concrete shelter that comes in kit form…  just add water and an hour later… voila, a concrete shelter!  OK, so it does weigh half a ton to start with, but then expecting it to be light as a feather to boot would be a bit much.

Reminds me of those cake mixes I tried to make while in digs, which never quite looked like the picture on the box, but were never the less hugely enjoyed.
