The most abundant source of "cole" I know of is Nat King Cole. After you were done frying him up to heat your saloon, you''d have to go looking for daughter Natalie to keep you warm.
Maybe this
stove doesn''t burn Cole <i>per se</i>, but Cole''s music (there are some that would be happy to see Natalie''s recordings go up in smoke). Not as grisly, perhaps, but I''m not sure how many BTUs you could get out of records, tapes and CDs, not to mention the evnironmental impact of burnning all that vinyl and plastic.
I suspect this
stove was actually designed to burn <b>coal</b>, the fossilized remains of plant matter. This cheap & abundant natural resource fired the furnaces of the second Industrial Revolution (giving many miners Black Lung Disease in the process).

(Okay, so I''m bored and pedantic. No offense intended; just having a bit of fun @ word-play. Hey, if it was good enough for Shakespeare...)
