we had an all-day power outage during an ice storm year before last. I used 4 votive candles and had a rack to set over them and warmed up a small pan of enchiladas and heated some water for tea. Takes quite a while to do that but we were getting cold and needed something. You can get small propane cookers or butane cookers to use indoors, better to use outside or on a covered deck or in a side room with the windows open though. Also I have a rocket stove and can use a tin of Sterno in it, fits perfectly in the stove. I have an unseated sunroom I could use it in. Could also refill the Sterno containers with denatured alcohol and cotton balls.
