Using thermic technology, the jacket would have a padding of limestone, when a strip is released this would allow sea/river water to mix with the limestone and create heat, helping to warm survivors until help arrives.

I don't know much about thermo technology, but this sounds like a wonderful idea. If the limestone is activated by water, it could also be used for saving anyone in cold conditions providing there was a water pouch within the jacket.

So you start off with a jacket full of stones, then flood it with water? That'll make a warm meal for the fishes, i suppose..

If Kate Winslet had one on the Titanic she woul'd have snuffed it would she, maybe.

Anything that could be used to kill any cast member of that film gets a croisant. You're a genius.

I don't think giz was trying to kill her, possibly save her in the freezing temps - maybe?

Common exothermic substrates (magnesium iron alloy and sodium chloride) produce enough heat to fry you if you don't adjust the quantity used with great care. Me, I think I'd stow a dry suit instead.

What's all this about cold typists [arora]?

So either she drowns, freezes or fries, reensure?

I like those odds ;op

I note that we have not heard from [gizmo] of late. Somebody, back in 2002, should really have explained to her that what is needed is not limestone but quicklime. Limestone is noted for its rapid reaction with water, namely sinking.
