For what it's worth I'll mention that I started bringing that teapot as an emergency hypothermia prevention/correction tool. So I consider it as both a survival item and a comfort item. Certainly there are other suitable means of heating fluids but I like this one. The teapot format makes it easier to distribute hot water to a group. This is not only for soup or drink but also for filling hot water bottles. A hot water bottle is really great when you don't have enough insulation, which is most likely to be the case in a survival situation.
