Egloo is a possible answer to the ever increasing heating bill. Only in the concept phase at the moment but you can support the project on Indiegogo. The idea is to use four candles inside a terracotta dome that heats up the dome and slowly release the heat, well after the candles went out. The four candles are enough to warm up a 20 square meter room and provide five hours of heat. All that heat for only 10 cents.
