If you guys ever get to visit Scotland, then I urge you to visit the Falkirk Wheel. It is a landmark in Scotland's engineering, art and tourism industry.
This collosal structure is the only one of its kind in the world. By the means of rotatory components, it links two canals vertically. You can even ride on a barge and it'll go up.
They claim that it only requires 22.5kW to execute a single cycle, which is the equivalent of two showers. It may be hard to believe but it's been designed with energy efficiency in mind. By applying Archimedes' principal and the conservation of momentum, the wheel obtains perfect balance despite having a 50 ton barge on one end and a small kid on the other.
On a glorious day, you get some stunning views too.
Mark, you only live like 1 and a half hours away. Get your ass over there to witness this masterpiece.
