I don't know what the heat content of charcoal is. Wood runs around 5,000 btu/lb assuming a 25% water content. Considering the temps Iowa has experienced the past 3 weeks perhaps a 70/30 ethanol/water mix would be more appropriate. Homegrown 140 proof moonshine requires considerably less energy to produce than the 200 proof stuff required by gasoline blenders.

Carbon is 14,500 Btu/lb. Charcoal is (mostly) the fixed carbon part of the wood and the ash. It looks like something on the order of 12000-12500 BTU/lb is about right.
