Is it Possible to Heat a House with a Candle

This has some material defects.... the OIL (vegetable oil) candle will char up it's wick with gum as the oil cooks and bakes hard as it gets towards the flame zone.

ALSO that laying a wick up the side of a glass jar is exceedingly dumb, as the co-efficient of expansion, from a zone of high temperature glass - to a surrounding not so hot, to slowly warming vessel overall, is highly likely to cause cracking or breaking of the glass, especially if the wick is thick enough to allow a hot layer (combustion) to run down into the glass, as the oil level lowers as it is consumed.

AND this guy who made the video left out the important bit that the ancient oil lamps used terra cotta ceramic lamps and not glass - and these were inherently crack resistant - being a "soft" baked clay (terracotta), and the wick did not lead into the oil, but out on a spout...
