How would you stay warm if the power went out during a winter storm? If you only have one answer to that question (or no answer at all), it’s time to prepare some extra emergency heat sources. As they say, two is one and one is none.
If your main source of emergency heat is damaged, out of fuel, etc., then you’ll need a backup plan. This article from Preppers Survive has some interesting suggestions.
For example, you could make a candle heater from terracotta pots and tea light candles. Or you could build a kotatsu, a Japanese method for trapping heat from burning charcoal. And if your bed is cold and too far from your heat source, you could heat up some rocks and put them in your bed. Follow the link below to check out their other ideas.
