In my previous post I discussed about saving money on heating bills using wood heat. Is wood heat more inexpensive than natural gas, electric, oil, or propane? One would tend to answer yes, but not so fast, hunches are fine but in order to definitively answer that question you need to run some numbers.
What you can not measure or calculate you have to rely on hunches and while hunches are a good first cut at answering a proposition they can often be wrong.
I keep coming back to the E85 situation, it is cheaper to fill your vehicle with E85, your money is staying local and going to local corn growers & ethanol plants so that may bias you into concluding E85 is more inexpensive, but when you calculate the cents it costs you to drive a mile on E85 vs. E0 or E10 my experience shows the hunch wrong — E85 is more expensive!
Onto calculating heating value.
