An aerial tram in Claughton, Lancashire, has been delivering rock from a quarry to the brickworks for 100 years now in a system that requires no power. This ingenious delivery course runs on gravity alone. That doesn’t mean it’s free, because there is some danger and important maintenance concerns, but even a computer couldn’t come up with a better system. In this video, Tom Scott obviously had to let the brickworks brag about their products a little to get the interviews. Still neat.
