Necessity is the mother of invention, and when electricity is a luxury deep in the wilderness, one man's invention calls on a one-horsepower treadmill.  Your eyes are not deceiving you.  That's actually a horse powering a treadmill that, in turn, powers a log splitter.

There are so many questions I'd like to ask.  First, does the horse enjoy the treadmill, or is it like being forced to go to the gym for 45 minutes?  Second, what came first, the idea for the horse treadmill, or the idea for a treadmill that powers a log splitter?  Finally, can I get the specs on how to make the kids power their new Xbox One via treadmill?
