This comment clarifies the behavior of the one-dimensional momentum model used by Tyagi and Schmitz in the high- and low-tip-speed-ratio limits, explains the torque–power constraint in the limit $\lambda \to \infty$, states where model assumptions do not hold when equations are continued outside their domain, and notes reproducibility and citation issues.

This study compares circular and figure-of-eight flight patterns for airborne wind energy systems, evaluating power output, stability, and system lifespan. Findings indicate that circular paths maximise energy generation in confined spaces, while figure-of-eight trajectories, particularly those ascending through the centre, provide smoother, more consistent power and extend kite longevity. These insights contribute to the improved design and performance of kite energy systems.
