Laddermill

Definition

A laddermill is a type of airborne wind energy system that consists of a series of kite-like structures attached to a long tether, which is used to harness wind energy at high altitudes. This innovative design allows the system to operate efficiently by taking advantage of stronger winds found at higher elevations, aiming to generate renewable energy with minimal ground-based infrastructure.
