So this Russian guy was sick of using his legs to get around like a sucker, so he turned a lawnmower engine into a back-mounted propeller. He's a hero.
Just watch this video! He straps on this huge contraption, puts on some skis, and then manages to tool around on the snow at up to 25MPH. It's amazing, and I want to try it immediately. Sure, you've gotta live in the snowy north of Russia for it to make much sense on a day-to-day basis, but man does this look like fun.
