I just saw these pics of the Falkirk Wheel on The Cellar's Image of the Day, and I figured I had to post them immediately. Apparently, two canals were coming at each other, one 24 meters higher than the other, so instead of simply building a bridge, the Scots did one better: they built a gorgeous engineering marvel. The Wheel works by lifting 300 tons of water and ship up on one end while simultaneously carrying 300 tons of water and ship down on the other. And while it does look like traffic jams could occur if too many boats were traveling between the canals, the system really is a thing of beauty. Click here to see more images.
