    en.wikipedia.org/wiki/Poncelet_wheel

    Typical efficiency of water wheels exploiting only the kinetic energy was around 30%. [1] These wheels are called stream water wheels, or kinetic water wheels. Instead, undershot water wheels are used in low head sites, like less than 1.5 m, and they also exploit the potential energy of the flow, with efficiencies of up to 84%.
