Silvert, W.
Some previous work on the theory of power and optimal efficiency in ecology is shown to be either incorrect or of limited applicability. The standard analysis based on Atwood's machine is not valid, and the optimal efficiency for maximum power production depends on the characteristics of the individual system. For optimally foraging aquatic organisms the theoretical efficiency is less than 50% when the hydrodynamic flow is laminar, but under turbulent conditions the optimal efficiency can rise as high as 67%. Despite these restrictions it still appears plausible that ecological efficiency should be the same for broad classes of living organisms.
