The Falkirk wheel is and engineering marvel that is a rotating boat lift. The wheel moves boats from the Forth and Clyde canal to the Union Canal. It was opened in 2002 and is part of the Millennium project and cost £32 million and took 3 years to construct.
The Falkrik wheel raises boats from the basin at the bottom, some 24 metres (79 feet) to the Union Canal above but locks above and below the wheel are still required to climb the difference in height between the two canals. However this is much easier than the 11 locks previously used prior to them falling into disuse in the 1930’s.
The wheel itself is quite a sight to see in operation and is virtually silent and uses very little electricity to operate and once operation of the lock consumes about the same electricity as boiling 8 kettles. The information on Wikipedia (Falkirk Wheel) makes interesting reading.
Anyway here’s a video of the Falkirk Wheel in operation and pictures are below.
