Life jacket to save people in cold water situations

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]?

       You just can't get friendly staff nowadays.

       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.

       Tell us again why that's a bad thing ... ?
