Based on the displacement theory as described by Archimedes, the Falkirk Wheel lifts canal traffic through the 17.5m height difference to allow efficient transit between the Union and Forth & Clyde Canals. Prior to its construction this required a day navigating eleven traditional locks. The struture is basically a huge balance whose equilibrium is upset by a nudge from about 18kW of electric motor power to start it on its rotational journey. A further 1.5kW keeps the balance rotating to transfer upper and lower gondolas, complete with their cargos of canal boats. Thoroughly amazing, the only such device in the world and it's here, on our doorstep. If you haven't been, get there, soon!
