It is fundamental and practical to understand the basic hydrodynamic principles of bouncing droplets on superhydrophobic surfaces develop control strategies. Although recent research has focused adjusting contact time droplet, little attention been paid manipulating rebound droplet from perspective energy optimization, which determines development long-term continuous dynamics. Here, we study impact water an anisotropic surface at a low Weber number 3.85, where bounce vertically after impacting gyrotron tangentially speed 7200 rpm. The initial kinetic required can be reduced by more than double relative traditional behavior same distance in horizontal direction. This proposes low-energy long-distance transport method for droplets, providing valuable insights enabling energy-efficient applications, including self-cleaning surfaces, liquid transfer, spray cooling industrial settings.
