The Falkirk Wheel is a rotating boat lift connecting the Forth and Clyde Canal with the Union Canal near Falkirk in central Scotland. It consists of two diametrically opposed caissons which rotate to transfer boats between the two canals through a height of 35 metres. Thanks to Archimedes' principle, the caissons always weigh the same, whether carrying up to 600 tonnes worth of canal barges, or just water. As such, the wheel is always perfectly balanced and despite its enormous mass, rotates through 180° in less than four minutes using just a few kilowatts. Photo credit: SeanMack |
