Can you explain the process through which wind energy was converted to mechanical power in these windmills?

In Mallorca, traditional windmills, known as "molins," were historically used to convert wind energy into mechanical power primarily for milling grain and pumping water. The process begins with the wind turning the large sails or blades of the windmill, which are designed to capture wind efficiently. As the blades spin, they are connected to a shaft that transmits the rotational energy.

This shaft is linked to a series of gears or pulleys, which further amplify the mechanical power. In windmills used for grain milling, the rotation of the shafts drives a set of grindstones, allowing the grain to be ground into flour. When used for water pumping, the mechanical motion might operate a crank or a pump that draws water from wells or irrigation systems.

The design of these windmills was highly efficient for the local conditions, taking advantage of the strong, consistent winds typical in the region. Over time, many of these traditional windmills have been preserved, serving as historical landmarks and attractions, while modern wind energy projects in Mallorca utilize advanced technology to harness wind power for electricity generation on a larger scale.
