From the time I started to cook outside I've wondered about the difference
in Cost between charcoal and gas. I began to work on a spreadsheet about
this and so far I've come up with the following table.


BTU/lb Charcoal

If I'm correct the cost is much closer than I thought, though the
variability is only hinted at above. When you grill you turn the gas on when
you begin and off when you end. When you use charcoal you light so many
pounds of charcoal. The charcoal burns until it goes out. Different types
and brands of charcoal have different BTU's per pound of weight. I would
guess a gas smoker may consume as little as 3-5000 BTU per hour. If anyone
knows I'd appreciate knowing.

Please let me know if any see errors. If you have other thoughts about this
I'd appreciate hearing.

Please disregard below. I'll try to resend.
