In 2002, Scotland opened a giant rotating wheel that lifts boats 115 feet, using about as much energy per turn as boiling eight kettles

The Falkirk Wheel, an engineering wonder in Scotland, connects two canals with its unique rotating lift design. Leveraging Archimedes' principle, it streamlines boat transportation significantly, reducing what once took a day through eleven locks. Remarkably, the wheel only uses as much energy as it takes to boil eight kettles, making it an eco-friendly marvel that attracts countless tourists every year.
