With all the winter related posts of late for food, fires, etc I have seen numerous references to emergency stoves/compact stoves. I only day hike so I have never even looked into a stove and really know nothing about them. Is there such a thing as a compact "emergency" stove with some sort of stable fuel that can be used for providing warmth, possibly heating up a frozen water bottle or other similar functions? I've seen many threads mention stoves and fuel but generally that is for cooking and overnight backpacking. If there is such a thing as an emergency stove (as in lightweight, easy to light in horrible conditions, etc) I'd be curious to learn more.
Here's my take on it...
CONTEXT - When I pack for a trip, I think of emergency gear in a larger context. I carry the same core set of things anytime I'm in the woods (See:
http://home.comcast.net/~pinnah/DirtbagPinner/essentials-list.txt) , and really, when staying the night in the winter, I'm already carrying a full camping kit. Emergency gear for a winter day trip is really tricky then because it is more than my 10 Essentials Kit and less than a full camping kit. Additional emergency gear starts adding things and weight and complexity that starts to move towards a full camping load. Tarp? Bivy? Bag (for an injured party)? Stove? I think a lot about Chouinard's adage that if you bring bivy gear, you'll use it (because the additional weight will slow you down) and the corresponding adage that "speed is safety". This is true and I've used light weight and the resulting speed to get out of Dodge on many occasions. But, a twisted ankle is all it takes to pin somebody down far from the trail head on a winter evening. I would be lying if I said I'm confident on every trip with every gear selection, which includes what NOT to bring.
PRACTICE MAKES PERMANENT - IMO, the number one issues with stoves of any sort is practice. My tradition for getting to know a stove is to make tea on it daily (or as close as I can) for a month in all weather conditions. Muscle memory and confidence result. I'm currently doing this with my Emberlit wood stove. (See:
http://www.emberlit.com/) I am very, very confident with my Svea 123. Almost as confident with my Trangia Mini (modified). I'm not there yet with the Emberlit.
SYSTEMS, NOT STOVE - IMO, all stoves require some additional weight and gear. Pot, windscreen, thin plywood base (prevents melting into the snow or loosing prime), fire starter of some sort and fuel. That is, it's not just stove. It's a full stove system. Here's a photo set that describes my "system" for the Trangia. I use the same pot(s) and windscreen with my Svea.

WHITE GAS ROCKS - I put away the Trangia at the end of October and don't get it back out until May. Even on a weekend trip, I find the hotter burn of the Svea 123 to be infinitely better.
BUT THE EMBERLIT MAY BE BEST - In terms of
WINTER DAY TRIP EMERGENCY STOVES, I could easily see the Emberlit being the best choice (at least for below treeline). It is very easy to light, is very miserly in terms of wood usage (minimizes harvesting impact), burns wood down to clean ash nearly all the time (minimizes ash/charred wood impact) and, unlike the Svea, can be used as an on-going fire source for warmth through the night provided you harvest the wood. I must emphasize that the Emberlit burns wood about thumb thick so in most situations, wood harvesting is a matter of breaking off twigs from dead fall. I carry cut up sections of tack cloth to act as a fire starter of last resort but a bit of birch bark will spark it up real quick. Since there is no fuel needed (beyond back up tack cloth or some other fire starter material which I think makes sense to carry anyhow in the winter) it is lighter than even my Trangia. Light, versatility, not horrible impact... For day trips, I think this will bump the Svea aside. When the sun goes down and I'm under equipped, I want the flames of the Emberlit not the blow torch and then out of the Svea. But, I need to finish off this month.
