I found an article online about how to easily heat a room using tea lite candles, and flowerpots, and it can actually be done for pennies a day. The basic idea is to take 4 little tea candles and put them into a loaf pan, and then you invert a small clay flowerpot over the top, and cover the hole with a quarter, or other similar sized object. You then put a larger flowerpot over the first one, but leave the hole uncovered, thus creating a heat trap, and it will escape out the top, and from the warm sides, and will warm up your room. This would be great to do if the electricity goes out, or even just for a little extra heat in a chilly room. Please Log In to view this link!
