CraftyPod points us to the very clever Kandle Heeter™, a handmade, low tech contraption that acts as a space heater. It's a collection of terra cotta pots with a solid steel inner core made up of hex nuts and washers and things, which collect the heat of a candle or, new for 2008, a halogen light bulb. You can buy the candle version for $29.95 and the electric version is $49.95; however, the generous creator provides how-to instructions to make them. He calculates the cost of the DIY candle version to be about 23 to 33 bucks, of course, we may have some of the supplies on hand, which means our costs could be considerably less. If you're more interested in an electric variety, there's also instructions for that one as well!
