Oh yeah, it has a lot of holes! Despite the effort I put in, I should have called it what it is: back of the envelope analysis. The only reason I did it was to satisfy my curiosity regarding the initial statement, then felt compelled to share it. :)
I doubt they let the logs dry at all, but the only caloric content I could find for logs assumed air-dried to 20%. I don’t know enough to consider other methodologies like carbon content, etc.
My 100 km was intended as a rate of energy consumption, not an actual hauling distance, but I didn’t make that clear.
