Everyone will think this is boring, except Adam, who will think it is quite intriguing, and I don't know about this forest guy - I have always imagined a forest man would be like harry from

Anyway, for what it is worth, here are some lower heating values:
Pure H2: -51567 Btu/lbm
50% H2/50% CO: -7154 Btu/lbm
CH4: -21506 Btu/lbm
Sorry about the archaic units - that is what I wrote my calculations in because I was coerced to do so...
Fascinating, though, huh?
