I have nothing to contribute to the thread because Ken did an awesome job of summing it up, but you really are stuck on this, huh?
Here's my guess: He found an object like a stone *a stone is actually a unit of measurement* and found how many horses it took to pull x amount of stones. Now, taking that into account, you can figure out how much energy it takes, etc...
