røremøller

Røremøller, also known as wave mills or wave-powered mills, are mechanical devices that harness the energy of ocean waves to perform useful work, such as grinding grain or pumping water. These mills have been used historically in various coastal regions, particularly in Scandinavia, where they were an important part of rural industry and agriculture.

The basic principle behind røremøllers involves the conversion of wave energy into rotational motion. This is typically achieved through a system of floats or other mechanisms that move with the waves, driving a series of gears or other mechanical components. The rotational motion can then be used to power a millstone for grinding grain, or to operate a pump for water management.

Røremøllers were particularly prevalent in Norway, where they were used extensively from the 18th century until the early 20th century. The most common type of røremøller in Norway was the "Norwegian wave mill," which featured a large, floating wheel that moved up and down with the waves. This wheel was connected to a vertical shaft that turned a millstone inside a small building, usually located on the shore.

The use of røremøllers declined with the advent of modern, more efficient milling technologies, such as steam-powered and later electric mills. However, they remain an interesting example of early renewable energy technology and a testament to human ingenuity in harnessing natural forces for practical purposes. Today, a few preserved røremøllers can still be found in museums and historical sites along the Norwegian coast.
