This isn't the first time someone's resorted to harvesting watts for their Pokéwalker without going outside for a quick stroll down the block -- as evidenced by this hilarious scheme -- but it is by far the most ridiculous one I've seen yet.
The video above displays how the nefarious contraption works. Essentially, the device violently shakes an unsuspecting Pokéwalker by tapping into the raw power of K'NEX. That's it. Simple, yet brilliant. Don't you go getting any funny ideas on me here -- you'll have to earn those watts the old fashioned way.
This .gif sums it all up rather nicely.
