心臟跳動的節奏可以減少湍流的程度，降低了循環流體所需的能量 (The Rhythm of Beating Hearts Reduces the Energy Needed to Circulate Fluids by Reducing the Amount of Turbulence)
像心臟一樣運行的泵，管道中的阻力減少了 27%，整體能源效率比常規連續運行的泵提高了 9%。
(Pump to operate like a heart, however, in both being pulsatile and having a rest phase, turbulent flow in the pipe became laminar. The result was a 27% reduction in drag and a 9% overall improvement in energy efficiency over a conventional continuously running pump.)
