From the top of the Falkirk Wheel with the Ochil Hills as a backdrop! The wheel resembles a giant double-headed axe or Celtic-inspired structure and rotates like a seesaw. Here's the clever mechanism:Two large gondolas (caissons) sit opposite each other on the wheel's arms, each filled with water and capable of holding boats. Boats enter a gondola at the bottom (Forth & Clyde level) or top (via an aqueduct leading to the Union Canal). As the wheel rotates 180 degrees (taking about 5 minutes for a full cycle), one gondola rises while the other descends. The system stays perfectly balanced thanks to Archimedes' principle: A boat displaces its own weight in water, so the gondolas remain equal in weight regardless of the vessels inside. Sophisticated gears (including a fixed "sun" gear and rotating "planet" gears) keep the gondolas level at all times, preventing the water and boats from tipping out. Power required is minimal — roughly 1.5 kWh per rotation, equivalent to boiling about 8 kettles — thanks to hydraulic motors overcoming mainly friction. HFF and a good weekend to all, A large view for detail please! A short time lapse video available here. www.youtube.com/watch?v=ucg1O-5jsnM
