Physics-wise, you get the heat of burning a candle in the room, no matter what nonsense you do to it.

On my periodic inspections I sometimes see candles set up decoratively inside the firebox and stockings hung by the chimney with care.

These being social references not political, but politics follow social demands.It was the beginning of "the great society", racial equality, expansion of health care, equal opportunity, voting rights, all during the reduction of nuclear threats and cold wars.That night, candles were placed in windows in East and West Berlin in honor of JFK, humanity overcame differences. :)

Its been around so long that farmers used to use a candle at the starting point to keep grade, check alignment, and dig them by hand for farm drainage.The county took it a step further and you can find clay tiles around 12" or bigger where there is alot of farm land.

@Goeran Sonstrand: @Kyle Hipp is correct.

It even prints a hard copy and spits it out of it's belly for the visitor to take home their copy.Agents can use drones to turn on lights, air conditioning, light a scented candle, music before a client visits.When the grass is too tall the drone can even mow the yard.That sounds more realistic and reachable then delivering octocopters.

Maybe he left a candle burning.

Unfortunately, their construction business picked up so much that they were burning the candle on both ends so they couldn't help us out.

@Kyle Hipp,I was a silent partner in a large complex in Dallas for over 15 years, and I have interviewed tenants from all walks of life, and a three-year address was ok with me.

It's them buying a bunch of cheap candles to light everywhere.
